Poised to revolutionize digital photography for advanced enthusiasts and professional photographers, the 12.1 megapixel Nikon D3 features one of the fastest startup time and shortest shutter lag of any digital SLR cameras.

With a MSRP of $4,999.95, the Nikon D3 is beyond most photographers, but for those who can afford it, is surely one of the best digital SLR cameras around. The Technical Image Press Association (TIPA) named the Nikon D3 the best professional digital SLR camera for 2008.

Professional Digital SLR Camera

Revolutionizing Digital Photography

MELVILLE, N.Y. (AUGUST 23, 2007) - Eight years after Nikon's D1 camera changed professional digital photography forever, Nikon today introduced the D3 - a new digital SLR camera that is poised to once again revolutionize photography for professionals. The 12.1 effective megapixel D3 features Nikon's new FX-format CMOS sensor, measuring 23.9 x 36mm, which is nearly identical to the size of 35mm film. With the fastest startup time, shortest viewfinder blackout time, and shortest shutter lag of any digital SLR camera as well as the capability to shoot up to nine frames per second at full FX-format resolution, the D3 is the world's fastest digital SLR camera in its class.

Designed with sports photographers and photojournalists in mind, the Nikon D3 introduces an astounding list of brand new features and technologies that make it the most sophisticated and advanced Nikon digital SLR to date. In addition to the new FX-format CMOS sensor, the D3 incorporates Nikon's new EXPEED Image Processing System that is central to the blazing speed and processing power needed for many of the D3's new features.

Images taken with the D3 reflect exceptional overall quality, broad tonal range and depth, along with extremely low-noise throughout its normal ISO range of 200 to 6400. By setting the camera to its built-in options of Lo-1 or Hi-2, the ISO range of the camera can be expanded to the equivalent of ISO 100 or ISO 25,600 respectively, offering unmatched versatility in practically any shooting situation.

The D3 also features an entirely new 51-point auto focus system with Nikon's 3D Focus Tracking feature and two new LiveView shooting modes that allow photographers to frame a photograph using the camera's high-resolution LCD monitor. The D3 uses the world's first Scene Recognition System to greatly enhance the accuracy of auto focus, auto exposure and auto white balance detection in the camera by recognizing the subject or scene being photographed and applying this information to the calculations for the three functions.

"Nikon is proud and excited to once again respond to the needs of professional photographers by introducing the D3. Nikon engineers have successfully combined ultra high-speed shooting capabilities and handling with outstanding low-noise image quality, offering professional photographers an ideal tool for a broad range of shooting disciplines," said Edward Fasano, general manager for Marketing, SLR Systems Products, at Nikon Inc. "Sports, commercial and press photographers are increasingly demanding higher ISO sensitivity, better resolution, wider dynamic range and a familiar depth-of-field in relation to picture angles. With the D3, Nikon is excited to deliver a solution that represents an ideal unification of unsurpassed image quality, high-speed operation and professional durability, without compromise. Nikon fully expects the D3 to positively affect the photographic community in a way that hasn't been seen since the introduction of the Nikon D1."

Nikon's Digital Camera Sensor Formats

Nikon's digital SLR cameras based on its DX-format sensor have been hugely successful and represent an excellent combination of high image quality, size and value. And while the DX-format has been widely accepted by professional photographers and photo enthusiasts around the world, there is an increasing demand among professionals for a digital SLR camera that features higher ISO sensitivity, wider dynamic range and offers the same relationship between picture angle and depth-of-field that were the hallmarks of the 35mm film format.

Responding to this demand, Nikon has developed the D3 as its first digital SLR camera that features the Nikon FX-format CMOS sensor to meet the real-world requirements of its professional customers. The D3 delivers full resolution 12.1 megapixel images at up to nine frames per second when used with conventional AF-Nikkor lenses. When used with DX Nikkor lenses, the D3 automatically switches to the DX-format mode that uses a cropped portion of the sensor to generate 5.1 megapixel resolution images. While in this mode, the D3 automatically masks the portion of the viewfinder that will not be photographed and enables the capability to shoot up to 11 frames per second.

Both Nikon FX and DX-formats provide their own advantages, and Nikon recognizes that both formats are necessary in order to satisfy its diverse customer demands. Based on this recognition, Nikon will strengthen its D-SLR lineup with the addition of the D3 FX-format SLR camera and a broadened assortment of Nikkor interchangeable lenses, while continuing to develop and market high-performance DX-format cameras and lenses.

The Most Intelligent Nikon Digital Camera Ever

The D3 introduces a range of innovative technologies and features that significantly improve the accuracy, control and performance professional photographers can get from their equipment. Nikon's exclusive Scene Recognition System advances the use of Nikon's acclaimed 1,005-segment sensor to recognize colors and light patterns that help the camera determine the subject and the type of scene being photographed, before an image is captured. This information is also used to improve the accuracy of auto focus, auto exposure and auto white balance detection functions in the D3. For example, the camera can track moving subjects better in all directions and by identifying them it can also automatically select focus points faster and with greater accuracy. It can also analyze scene highlights and more accurately determine exposure, as well as infer light sources to deliver more accurate white balance.

The D3 incorporates Nikon's new Multi-CAM 3500FX auto focus module that features an intelligent array of 15 cross-type sensors and 36 horizontal sensors. These sensors can either be used individually or in groups, with the option for Single Area AF mode and Dynamic AF modes using groups of either 9, 21 or all 51 focus points. The system also features 3D Focus Tracking with automatic focus point switching that takes advantage of all 51 AF points as it uses color and light information to accurately track the subject. Nikon's new Scene Recognition System and improved focus algorithms also contribute to the impressive performance of the new 51-point AF system.

Nikon's new Picture Control System makes it easy for users of all experience levels to select and apply adjustments to how their pictures are rendered and create optimized settings to suit their individual preferences. The same settings produce consistent picture tone, even when using different camera bodies. The Picture Control System offers four basic setting options – Standard, Neutral, Vivid and Monochrome. These can be directly modified for easy adjustment and customization of image parameters, such as sharpening, tone compensation, brightness and saturation. Photographers can customize and store up to nine customized options in the D3 and export up to 99 to a CF memory card, enabling photographers to share settings among multiple D3 cameras.

Taking a cue from the popularity of Nikon's D-Lighting technology, the D3 features a new Active D-Lighting mode that, when enabled, provides remarkable real-time highlight and shadow correction with optimized image contrast. Active D-Lighting produces broader tone reproduction in both shadows and highlights by controlling highlights and exposure compensation while applying localized tone control technology to achieve a more pleasing level of contrast across the entire image. And because the advantages of Active D-Lighting are applied as images are captured, image editing time can be shortened.

The D3's LiveView feature offers two modes for confirming subjects and composition on the new 920,000-dot, high-resolution 3-inch LCD monitor while shooting. The Tripod mode is designed for precise focus and accuracy when the camera is on a stable platform and the subject is not moving. In this mode, the camera focuses on the subject using focal-plane contrast and any point on the LCD screen can be selected as the focus point for the picture. The second mode, called Handheld mode, allows photographers to use the camera's conventional TTL focusing system, with all 51-points and 15 cross-type points available. When using this mode, the camera activates focusing immediately when the shutter button is pressed, to ensure accurate focus.

The Fastest Digital Camera in its Class

The D3 has the fastest reaction times of any camera in its class. Its shutter release time lag is only 37 milliseconds, and its start-up time is approximately 0.12 seconds. It is capable of continuously shooting approximately nine frames per second in full resolution with FX-format, up to 64 consecutive frames in JPEG, Normal compression. For NEF (RAW) files, the D3 can shoot up to 20 or up to 17 consecutive frames depending on whether it is set to 12-bit or 14-bit images. When using a DX-format lens, the camera automatically switches to DX-format mode, adjusting the resolution of the camera to 5.1 megapixels. In the DX-format mode, photographers also have the opportunity to increase the speed at which the camera can take pictures by limiting the auto exposure and going up to 10 frames per second or limiting both auto exposure and auto focus and going up to 11 frames per second.

Refined Ergonomics and Usability

The D3 reflects Nikon's most streamlined, functional and aesthetically pleasing layout in a digital SLR camera, all designed so photographers can take pictures with less fatigue, greater accuracy and comfort.

The camera's viewfinder provides virtually 100 percent coverage for accurate framing, while an ultra-high definition, 920,000-dot VGA LCD screen on the rear of the camera displays images with vivid color and clarity. The 170-degree wide viewing angle makes composing shots using the LCD screen in LiveView mode easy. The D3 also features a unique Virtual Horizon digital level sensor that indicates the camera's alignment relative to the true horizon on the rear LCD screen or in the viewfinder.

The D3 also features two CompactFlash card slots that can be used for consecutive recording (overflow), simultaneous recording (backup), separating recording of RAW and JPEG files or even copying pictures between the two cards. Images can be displayed directly from the camera to a high-definition monitor using the camera's HDMI port and an optional cable.

The D3 is designed for professional use in demanding conditions. The exterior of the D3 is crafted of magnesium alloy and the camera's shutter mechanism is tested to 300,000-cycle releases. The 3.0-inch LCD is strengthened with tempered glass and the D3's comprehensive array of rubber gaskets and seals protect vulnerable entry points from dust and moisture.

Full Review - Canon Rebel XSi Digital SLR Camera

Canon's new EOS Rebel series digital SLR camera - the Rebel XSi - places superior optics and the latest professional features into the hands of emerging photo enthusiasts. Together with optically image stabilized lenses, the new Rebel is a serious contender in the advanced digital SLR camera market. The Canon Rebel XSi is known as the Canon EOS 450D in Europe.

LAKE SUCCESS, N.Y., January 23, 2008 – Canon U.S.A., Inc.'s EOS Rebel series of digital single lens reflex cameras – the cameras that defined and refined what it means to be an "entry level" digital SLR – have now redefined the gateway prowess and "pro-ness" of the DSLR category with the introduction of the line's new leader, the 12.2-megapixel EOS Rebel XSi camera. Incorporating a number of high-end functions and technology found in Canon's professional SLR models, the EOS Rebel XSi camera boasts an improved autofocus sensor, enhanced 14-bit A/D conversion, an advanced Live View function, and the proprietary DIGIC III image processor. When paired with any of the more than 60 compatible Canon EF and EF-S lenses, including optically image stabilized EF-S lenses like the EF-S18-55mm f/3.5-5.6 IS – now included in the EOS Rebel XSi kit – or the new EF-S55-250mm f/4-5.6 IS, the EOS Rebel XSi DSLR delivers images that will delight and inspire family and friends at an entry level price tag.

"This new EOS Rebel XSi digital SLR camera is the answer for those who have been waiting to make the leap from digital point-and-shoot to digital SLR or from an older SLR to the latest generation of advanced technology, while still including the creative controls their old camera afforded them," states Yuichi Ishizuka, senior vice president and general manager, Consumer Imaging Group, Canon U.S.A.

Luxury Feel and Function

At first glance, one notices the Rebel XSi digital SLR camera's large, 3-inch LCD monitor, enhanced from the 2.5-inch screen on the Digital Rebel XTi model. The larger 230,000 pixel screen makes it easier for users to review images and scroll through the Rebel XSi digital SLR camera's menus. The larger-sized display provides the ability to use a larger font size for menu text, making it easier than ever to read settings and options. The new screen also features a broadened color gamut, seven brightness settings for easy viewing under a variety of shooting conditions and a wide viewing perspective in all directions.

The EOS Rebel XSi digital SLR camera features a substantial yet streamlined profile, with curved edges, contoured surfaces, conveniently placed controls and comfortably constructed rubber grip and thumb rest that all contribute to fatigue-reducing hand fit. The digital SLR camera body is constructed of a rugged yet lightweight combination of stainless steel and polycarbonate embedded with glass fiber. The chassis exterior is enrobed in a durable ABS and Polycarbonate resin and offered in a choice of silver or black finishes.

Improved Image Quality

At the heart of the new EOS Rebel XSi digital SLR camera is its newly designed 12.2 megapixel APS-C size Canon CMOS sensor. This new sensor employs large microlenses over each pixel to reduce noise and enhance sensitivity up to ISO 1600, which is ideal for high-quality images in low light. The APS-C size sensor retains a 1.6x focal length conversion factor compared to full-frame digital image sensors or 35mm film format cameras.

Another image quality enhancement is the upgrade of the Analog-to-Digital (A/D) conversion process to a 14-bit A/D processor. The inclusion of the 14-bit A/D process means the Rebel XSi camera records up to 16,384 colors per channel and allows the camera to produce images with finer and more accurate gradations of tones and colors. This is ideal for shooting outdoors where subtle hue changes in sky, water or foliage can really add to an image.

The Canon EOS Rebel XSi DSLR also incorporates the optional Highlight Tone Priority and High-ISO Noise Reduction functions first introduced in 2007 with the EOS-1D Mark III Professional Digital SLR camera and now available for the first time in an entry level Canon digital SLR camera. Additionally, the new camera is equipped with Canon's Auto Lighting Optimizer technology, which corrects image brightness and contrast automatically. Introduced last year in the EOS 40D digital SLR camera, this valuable optional feature now works in all exposure modes and utilizes Face Detection technology to prevent underexposure with backlit faces.

DIGIC III Image Processor

If the 12.2-megapixel APS-C size CMOS sensor is the heart of the digital SLR camera, then Canon's DIGIC III processor is the brain. The latest generation of Canon's proprietary image processing engine, DIGIC III technology ensures that the fine details and natural colors of the images are optimally recorded. The DIGIC III processor also manages the digital SLR camera's efficient energy consumption and high-speed signal processing performance. The EOS Rebel XSi is the first model in the Rebel series to incorporate DIGIC III.

Enhanced Live View

Introduced in 2007 on the EOS-1D Mark III DSLR, this function makes its debut in an entry level Canon DSLR with the EOS Rebel XSi digital SLR camera. Live View allows users to frame shots through the LCD screen rather than the viewfinder. Going beyond the manual focus and phase-detection AF capabilities of earlier EOS models with Live View, the EOS Rebel XSi digital SLR camera adds a new "Live Mode" contrast-detection AF function that allows the camera to focus automatically during Live View without lowering the reflex mirror.

Improved Autofocus and Framing Rate

The EOS Rebel XSi Digital SLR camera utilizes a precise nine-point Autofocus (AF) system featuring a newly developed AF sensor that improves the digital SLR camera's subject detection capabilities compared to earlier models. The new Rebel XSi DSLR provides a cross-type AF measurement at the center that's effective with all EF and EF-S lenses, while providing enhanced precision with lenses having maximum apertures of f/2.8 or faster. The cross-type AF measurement reads a wider variety of subject matter than conventional single-axis AF sensors and thus increases the new digital SLR camera's ability to autofocus quickly and accurately. The EOS Rebel XSi is also the fastest firing Rebel model to date, capable of continuously capturing 3.5 frames per second for bursts of up to 45 images in large/fine JPEG mode and 6 frames in RAW mode. The faster frame rates and finer focusing capabilities of the Rebel XSi together with its impressive image burst rate will help digital photo enthusiasts preserve family milestones or capture split second sports action at just the right moment.

EOS Integrated Cleaning System

The new Rebel XSi DSLR utilizes Canon's EOS Integrated Cleaning system, first introduced on the EOS Rebel XTi digital SLR camera. The camera's Self-Cleaning Sensor Unit shakes dust particles off of the low-pass filter in front of the sensor. The dust is then trapped by an adhesive along the base, preventing it from causing further nuisance. Cleaning is engaged each time the digital SLR camera is powered up or shut down or manually through the "clean now" function.

The second part of the cleaning system involves post processing with a compatible personal computer and the supplied Digital Photo Professional software. Here the camera maps any spots that may remain on the sensor, saving it as Dust Delete Data and subsequently subtracting dust spots from the final image during post processing. A third option includes a manual sensor cleaning function which raises the mirror and allows users to clean dust that may have stuck to the low-pass filter.

Back to the Basics

In keeping with its EOS system heritage, the new Canon EOS Rebel XSi digital SLR camera is equipped with a host of useful creative controls, including shutter speeds ranging from 1/4000 sec. to 30 sec. plus Bulb, a choice of four metering patterns including 4% spot metering (another first for the Rebel series), a wide range of exposure modes from fully automatic to fully manual, depth of field preview, mirror lock and much more. The new digital SLR camera is fully compatible with all Canon EF and EF-S lenses, as well as EX-series Speedlites, an optional Battery Grip, and remote control and viewfinder accessories.

A departure from previous EOS Digital Rebel models, which accommodated CF type memory cards, the new EOS Rebel XSi digital SLR camera utilizes SD and SDHC memory cards including those with capacities higher than 2GB, making it the perfect upgrade for users already equipped with SD cards from point-and-shoot model cameras. Additionally, the EOS Rebel XSi camera utilizes Canon's new high-capacity LP-E5 lithium ion battery pack, which provides 50% more exposures per charge than earlier models with virtually no increase in size or weight.

In the Box

Expected to ship in April 2008 the Canon Rebel XSi digital SLR camera is available in body-only configuration which includes a rechargeable battery pack and charger, USB and video cables, a neckstrap, an EOS Solutions Disk CD, and a 1-year Canon U.S.A., Inc. limited warranty. The new camera will also be available in a lens kit version which includes everything in the body-only kit plus the EF-S18-55mm f/3.5-5.6 IS zoom lens. The two versions carry estimated retail prices of $799.99 and $899.99, respectively.

EF-S 18-55mm f/3.5-5.6 Image Stabilizer Lens

First introduced in August of 2007, the Canon EF-S 18-55mm f/3.5-5.6 IS zoom lens is Canon's answer to consumer demand for a high-quality yet affordable optically image stabilized lens and is included as the standard lens in the Rebel XSi kit configuration. The lens features the wide-angle to mid-range zoom flexibility of its non-IS predecessor with the significant advantage of Canon's true optical, lens-shift image stabilization system that yields up to a full four stops of image-shake correction.

The higher performance provided by Canon's lens shift IS system (compared with the in-camera body sensor shift type offered in some competitive SLRs) includes the ability to optimize the lens performance for specific shooting situations such as low light, long-zoom or movement while shooting (or virtually any combination of the three). What's more, the photographer can see the optical image stabilization effect in the viewfinder. As the image already appears steady in the viewfinder or on the screen through the Rebel XSi Live View function, better framing and composition is possible allowing the photographer to concentrate on the best shot more comfortably.

EF-S55-250mm f/4-5.6 IS Lens

Like the standard kit lens, the optional EF-S55-250mm f/4-5.6 IS zoom lens offers users of Canon EOS Digital SLRs with APS-C type CMOS sensors an affordable, lightweight, high-performance lens with tremendous range and flexibility. Given the 1.6x conversion factor inherent in the APS-C sized sensor, the high zoom ratio of this EF-S 55-250mm lens actually achieves the equivalent focal length of 88-400mm (in 35mm format).

Canon's true optical, lens shift image stabilizer offers users an equivalent shutter speed that is approximately 4 settings faster, making hand-held lower light or long zoom photos easier to capture without blurring. What's more, the lens can automatically distinguish between normal shooting and panning shots and select the optimum Image Stabilizer mode for each.

In stores now, both the EF-S 18-55mm f/3.5-5.6 IS and the EF-S55-250mm f/4-5.6 IS zoom lenses are manufactured by Canon specifically for the EOS Rebel XSi , EOS 40D and every other EOS SLR that takes EF-S lenses including earlier Digital Rebel cameras and the EOS 20D, EOS 20Da, and EOS 30D models. Though standard in the EOS Rebel XSi kit, the EF-S 18-55mm f/3.5-5.6 IS lens is also available as a stand alone purchase and carries an estimated retail price of $199.99. The optional EF-S55-250mm f/4-5.6 IS lens is available at an estimated retail price of $299.99.

Full Review - Sony Alpha A200 Digital SLR Camera

Sony unveiled the Alpha A200 Digital SLR Camera, designed for entry-level photographers at CES 2008 in Las Vegas.

LAS VEGAS(CES BOOTH), Jan. 6, 2008 – Sony is advancing the digital SLR camera category for mainstream digital photographers with today’s introduction of the new α (alpha) DSLR-A200 camera.

The Digital SLR Camera-A200 model features upgrades influenced by the recently-introduced, enthusiast-class DSLR-A700 camera and replaces the former Sony DSLR-A100 model, which was Sony’s first in the digital SLR camera class.

The new model is designed to be faster, lighter and easier to use. Upgraded features include a wider, 2.7-inch Clear Photo LCD screen for easy playback viewing; a more compact body and an easily-accessible mode dial; an easy-to-use function menu (camera function display); improved noise control for higher quality images; an auto focus speed 1.7x faster than the previous digital SLR camera model; improved predictive control performance; quieter shutter sound; automatic pop-up flash; and a battery life indicator that displays the percentage of battery life remaining so you know exactly when to recharge.

As seen in all α (alpha) camera bodies, the Sony Alpha A200 digital SLR camera incorporates Super SteadyShot® image stabilization in the body to allow shooting at shutter speeds of 2.5 to 3.5 steps slower than otherwise possible – a benefit realized with every compatible lens attached to the camera. Compatible lenses encompass all Minolta Maxxum® mount lenses, in addition to Sony a (alpha) lens lineup - including Carl Zeiss® lenses.

“With the Sony Alpha A200 digital SLR camera, we are helping consumers capture high-quality images with advanced technology that’s practical and easy to use,” said Phil Lubell, director of marketing for digital cameras at Sony Electronics. “This model is an ideal step-up for point-and-shoot users who are looking for a camera that can capture virtually all of the photographs they want.”

High-Quality Digital Photographs

With its 10.2-megapixel (effective) APS CCD image sensor, the Sony Alpha A200 digital SLR camera continues to offer high-quality images by allowing more light to pass through to each pixel – increasing sensitivity, reducing noise, and providing greater detail.

Clean, reduced-noise signals are sent from the image sensor to Sony’s BIONZ processing engine, which processes data-rich picture information at high speeds and reduces picture noise in the RAW data stage before image JPEG conversion. The results are high-resolution, detailed images with rich tonal reproduction.

The Sony Alpha A200 digital SLR camera model supports JPEG and RAW file format support. It has a slot for CompactFlash Type I/II media cards. An adaptor for Memory Stick Duo™ media cards is sold separately as an accessory.

Get The Photo Results You Want

In addition to Super SteadyShot image stabilization for virtually blur-free photos, the new model incorporates Sony’s D-Range Optimizer (DRO). It helps you capture well-exposed images, especially when shooting high-contrast or backlit scenes that often lead to loss of highlight and shadow detail. Sony’s DRO modifies the range from highlights to shadows, including gain and contrast, through its in-camera hardware processing to produce more natural, evenly exposed pictures. The digital SLR camera’s image analysis technology studies the captured image data and instantly determines the best exposure and color tonality for the image before JPEG compression.

The BIONZ image processing engine powers the camera up immediately and the eye-start autofocus starts the focusing system before you even press the shutter. The Sony Alpha A200 digital SLR camera can shoot up to three continuous frames per second at 10.2-megapixels at the finest JPEG compression level.

As seen in previous α (alpha) models, the new model carries a static-free anti-dust coating on the CCD filter which is gently vibrated to dislodge any dust that might have collected each time the digital SLR camera is powered off.

Additionally, the Sony Alpha A200 digital SLR camera’s supplied lithium ion battery offers up to 750 shots per full charge.

Bright and Easy Digital Camera Playback

The Sony Alpha A200 digital SLR camera’s smaller, more compact body along with its wider, 2.7-inch Clear Photo LCD TM screen and a new on-screen navigation interface make it easier to carry and to use. The vibrant, easy-to-view screen features 230K-pixel resolution, an anti-reflection coating and glare-reducing layer assures vivid, accurate colors with a wide viewing angle, even in daylight. The on-screen navigation display shows camera settings and key shooting information in large, easy-to-read text. The Sony Alpha A200 digital SLR camera display’s orientation automatically switches from landscape to portrait position when the camera is turned on its side.

Accessories Expand Creative Possibilities

Sony is providing a full line of accessories for the model, including flashes, rechargeable battery packs and several carrying cases. An interesting addition to the Sony Alpha A200 digital SLR camera is the VG-B30AM ergonomic vertical grip equipped with the most essential controls for portrait orientation shooting. It also allows for the use of two InfoLITHIUM® batteries (sold separately) for up to 1,500 shots on a single, full charge.

The DSLR-A200K kit includes the camera body and a DT 18-70mm f3.5-5.6 3.9x zoom lens for about $700. The DSLR-A200W kit includes the camera body, the DT 18-70mm lens and a 75–300mm f4.5-5.6 lens for about $900. Both will ship in February 2008 and will be available at sonystyle.com, Sony Style® retail stores, military base exchanges, and authorized dealers nationwide.

Digital SLR Camera - Sony Alpha A200

The Sony Alpha A200 is an entry-level digital SLR camera with a 10.2 megapixel CCD image sensor and Sony's own Super SteadyShot image stabilization technology. It represents a step forward from its predecessor - the Alpha A100.

Making the Jump to Digital SLR Photography

Factors to Consider When Looking for a Digital SLR Camera

by Rajendra Varma

Digital SLR cameras are a must for anyone serious about their digital photography. Although amateur photographers may find all the features of a digital SLR camera overwhelming, for those with more experience in digital photography, making the jump to a digital SLR camera will be natural. Not only do digital SLR cameras offer better quality digital photographs, but the creative flexibility they provide is unmatched by other digital cameras.

A compact digital camera may be much more convenient to carry and produce good digital photographs, it simply cannot match the possibilities offered by a digital SLR camera. The bulkier digital SLR cameras will be harder to carry around, but their size is required to hold the more advanced hardware they carry. Bigger image sensors mean cleaner image data processing.

Interchangeable lens allow a lot more possibilities and better optical quality than a compact digital camera's miniature lens.

Important Digital SLR Camera Features

There are a number of important features to consider before buying a digital SLR camera.

Resolution

Resolution is even less of a problem today in digital SLR cameras than it is in compact digital cameras. The latest digital SLR cameras have upwards of 10 megapixels resolution, which is good enough for extremely large prints. A 10 megapixels digital photograph can be printed into a good quality 20x30 print. Therefore, digital SLR camera resolution is not really a big factor.

Lens

Normally, when you purchase a digital SLR camera, it will come with a starter lens that is a multi-purpose zoom lens covering a wide range of focal lengths from wide angle to telephoto. Although the starter lens, or kit lens, will produce digital photographs, it will not fulfill the digital camera's potential. So if you do take your digital photography seriously enough to purchase a digital SLR camera, then you should also think about purchasing a good lens. Depending on your personal preferences, you could look into wide-angle lenses if you are into landscape photography, or a telephoto lens if you want to take wildlife or sports photography.

Image Stabilization

Modern digital SLR cameras have image stabilization to compensate for camera movement. Image stabilization will be especially important in low-light situations or high-zoom photos. Each digital SLR camera manufacturer have their own solutions to image stabilization.

Shutter Speed and ISO setting

Digital SLR cameras usually have a wider range of shutter speeds and ISO settings available than their compact digital camera counterparts. Nevertheless, there is a variety of digital SLR cameras out there that offer different capabilities, and not all will offer the same settings. If you anticipate shooting very fast actions shots, it is a good idea to look for fast shutter speeds.

Flash

Even though digital SLR cameras will normally have built-in flash, this may not be sufficient if you would like to do night photography or portrait photography, for example. You will want an external flash to achieve optimal lighting conditions for your digital photography.

Burst Mode

Burst mode allow you to shoot multiple shots in a short period of time, and will be important in fast action situations. The better digital SLR cameras will shot upwards of 5 frames per second.

Ergonomics

This includes camera design and appearance, but also ease-of-use in terms of menu settings and digital photo previewing. Button placements and other factors will determine whether you will learn to use the digital SLR camera naturally.

Other factors

The above are just some of the basic features to look at when making the jump to digital photography. Depending on how experienced a digital photographer you are, you may look at other factors such as focusing capabilities, image processing, white balance, and shooting modes.

It is important to understand that the camera is the most important part of your photography, and therefore it is advisable to invest in a good digital SLR camera if you are serious about digital photography and the quality of your photos.

Digital SLR Photography

How To Take Stunning, Lively And Ravishing Pictures

by Connie Fillmore

Photography is digital SLR photography, at least to any self-respecting photographer. Suggest otherwise, and he is sure to give you a piece of his mind and proceed to praise the virtues of digital SLR photography.

Digital SLR photography uses a digital SLR (Single Lens Reflex) camera that uses a movable mirror placed between the lens and the film to project the image on to a focusing screen.

Digital SLR photography churns out the most amazingly realistic photographs, in fact much better than the ones turned out by the conventional fixed lens cameras. But its prime appeal to photographers, both amateur and professional, is in the fact that he can work out a large amount of control over how his pictures end up as.

Digital SLR photography is all about customized photographs that are stunning to look at, to say the least. This is because the cameras come with extremely good lenses. This is why the discerning photographers are not miserly about getting a lens, frightfully expensive they may be.

However, digital SLR photography enthusiasts should never think that a swanky Nikon or a Canon is the passport to great photography. The apparatus notwithstanding, good photography depends a lot on the skills of the person brandishing the camera. The basics of digital SLR photography are not hard to pick up.

The first and foremost tip about digital SLR photography is to equip yourself with the nitty-gritty of lighting. If you are shooting outdoors during the day it is best to have the sun directly behind you. It is also essential that your subject also does not have to face the sun so that he has to squint. You should know that the best time to film landscapes, buildings and outdoor portraits is either dawn or the twilight hours.

If you want to impart the warmth of the rising or setting sun to your midday photo shoot, then a skylight or a warm filter is your key.

Tips to great digital SLR photography insist on maintaining control over the camera's flash property. To be precise, don't have your camera have the last word about where the flash should come on. Take the reins yourself and ensure that your photograph subjects are not lost in a maze of bright light.

Good photography, digital or analog, SLR or otherwise, is all about being able to use the filters right. You never know when that polarizer or the gradual filter or the skylight/UV filter might come to your rescue at times when the light situations are tricky.

The Macro Mode atop the camera just happens to be the most underrated and under-used feature. But unknown to many, this mode is great for taking enchanting close-ups of tiny objects.

Realistic and stunning digital photography is actually the norm with plethora of controls that come with modern day digital SLR cameras. And photography tips harp on tinkering with the controls to get a hang of the controls and the outcomes they produce.

Experimenting for instance, with really slow (30 seconds) extremely fast (1000th-8000th/second) shutter speeds can produce dramatic results. The ISO setting is another area for experimentation. In fact, high ISO values come in quite handy when you cannot use a flash in low light situations.

Get well up on your digital SLR photography tips and tricks and shoot at sight willingly.

Full Review - Canon EOS D40 Digital SLR Camera

Canon announced the successor to the EOS 30D digital SLR camera in August 2007 - the EOS 40D. The EOS 40D features a 10.1 megapixel sensor along with the latest developments in digital SLR camera technology to produce images worthy of Canon.

Building on the success of Canon's perennially popular "prosumer" EOS 20D and 30D models, the EOS 40D advances the state-of-the-art for mid-range Digital SLR cameras, making it a natural first choice for advanced amateur photographers and entry-level professionals, and an ideal second body for more established photo pros. Indeed, given the level of feature upgrades and improvements, technological wizardry and user-requested creative controls, the Canon EOS 40D SLR's "prosumer" appellation may refer more to its accessible price point than to the exceptional quality, clarity and resolution of the images it creates.

From the camera's newly enhanced, 10.1-megapixel CMOS imaging sensor (designed and manufactured by Canon) and its proprietary and super-efficient DIGIC III image processor, to its completely redesigned autofocus sensor and fast, 6.5 frame-per-second (fps) continuous shooting capability (for bursts of up to 75 Large/Fine JPEGs or 17 RAW images), the EOS 40D SLR puts the fun in functionality and makes serious photo business a positive pleasure.

Indeed, at 6.5 fps, no Digital SLR in the EOS 40D mid-range class and price category has so high a continuous shooting capability, making it ideal for shooting – and actually capturing – speed-sensitive outdoor and wild-nature shots as well as a wide variety of action and sports scenes. The speed of the EOS 40D SLR comes from Canon's balanced combination of its latest processor, DIGIC III, DDR SDRAM high-speed memory, four-channel-per-line sensor readout, and two separate motors for shutter and mirror operation.

"This newest member of Canon's Digital SLR family takes mid-range Digital SLRs to exciting new heights with enhanced resolution and image quality, faster shooting and processing speeds and better overall functionality than ever before," stated Yuichi Ishizuka, senior vice president and general manager, Consumer Imaging Group, Canon U.S.A."The EOS 40D Digital SLR Camera incorporates many Canon innovations and advancements that differentiate our products from the competition, while respecting and reinforcing our long-standing traditions of providing superior value and innovative imaging technology."

Display's the Thing
The most easily visible upgrade on the EOS 40D Digital SLR is the camera's larger three-inch LCD screen (compared with the EOS 30D's 2.5-inch monitor). Still, size is only the beginning of the difference between these two cameras' displays. In order to increase viewing ease in outdoor conditions such as bright sunlight, Canon raised the brightness level of the EOS 40D camera's 230,000-pixel LCD screen, broadened the color gamut and narrowed the viewing angle from 170 degrees to a still wide 140-degree perspective in all directions. An added advantage of the larger-sized display is the ability to use a larger font size for text, making it easier to read setting and menu options on the screen. The camera's menu is organized in the same tabbed format as the EOS-1D Mark III Digital SLR.

Canon extends its "ease-of-reading" policy to the EOS 40D SLR's viewfinder as well. The upgraded viewfinder increases optical magnification from 0.90x to 0.95x, expands the viewing angle from 251 degrees to 264 degrees and raises the eye point from 20mm to 22mm.

Enhanced Durability
Recognizing the often rigorous shooting conditions encountered by professional and advanced amateur photographers, Canon design engineers made the EOS 40D SLR's magnesium alloy exterior even more ruggedly dependable than its predecessors with upgraded dust and weather resistant construction, particularly around the camera's connection ports, battery compartment and single-slot compact flash memory card door. Should the user inadvertently open the compact flash card door while the camera is writing to the card, a warning will pop up on the LCD screen and an open door "alarm" will sound, but the image(s) will continue writing to the memory card without interruption. The EOS 40D SLR also retains many of the outstanding features of the EOS 30D model, such as its fast 0.15-second initial start-up, its extremely durable shutter (rated up to 100,000 cycles), its top shutter speed of 1/8000 sec and 1/250 maximum X-sync flash shutter speed setting.

Improved Image Quality
Although it is based on the image sensor used in the EOS Digital Rebel XTi, the EOS 40D Digital SLR's 10.1-megapixel CMOS APS-C size image sensor has been significantly improved thanks to the use of larger microlenses over each pixel to reduce noise and expand sensitivity up to ISO 3200. The EOS 40D retains the model 30D camera's 1.6x focal length conversion factor (compared to full-frame digital image sensors or 35mm film) and is compatible with the full line-up of Canon EF lenses as well as the Company's expanding selection of high-quality, affordable EF-S lenses created specifically for Canon Digital SLRs with APS-C size image sensors.

Adding to the improved virtuosity of the images captured by the EOS 40D SLR is the camera's 14-bit Analog-to-Digital (A/D) conversion process. Able to recognize 16,384 colors per channel (four times the number of colors recognized by the EOS 30D SLR's 12-bit conversion capability), the EOS 40D camera is able to produce images with finer and more accurate gradations of tones and colors. The EOS 40D also incorporates the optional Highlight Tone Priority and High-ISO Noise Reduction functions first introduced earlier this year with the EOS-1D Mark III Professional Digital SLR.

DIGIC III
DIGIC III is the latest generation of Canon's proprietary image processing engine. DIGIC III technology ensures that the fine details and natural colors of the images are optimally recorded and, as an added bonus, is also responsible for the EOS 40D SLR's high-speed performance, faster signal processing and even its efficient energy consumption.

sRAW
In addition to retaining the RAW image capture capabilities of its predecessors, the EOS 40D SLR now offers a more manageable "sRAW" recording format. In sRAW mode, the number of pixels is reduced to one-fourth that of a standard RAW image and the file size is cut in half, while retaining all of the flexibility and creative possibilities associated with full-size, conventional RAW images.

Improved Autofocus and Exposure Control
While the EOS 40D SLR maintains the nine-point wide area AF coverage first introduced on the EOS 20D camera, Canon has made significant improvements to its speed, precision and functionality, minimizing subject recognition problems in the process. The EOS 40D camera's completely redesigned nine-point AF sensor provides cross-type AF measurement at all nine focusing points for maximum apertures up to f/5.6, and for the first time in any EOS camera, the central AF point offers enhanced precision for both vertical and horizontal subject contrast when using EF or EF-S lenses featuring maximum apertures of f/2.8 or faster. AF calculation speed with the EOS 40D camera is 30 percent faster than the EOS 30D model.

The Canon EOS 40D Digital SLR retains the same 35-zone metering sensor as its predecessor. Available patterns include Evaluative metering, which is linked to all AF points and is set automatically in the Basic Zone modes, Centerweighted average metering, Partial metering and Spot metering, covering approximately 9 percent or 3.8 percent of the viewfinder at center, respectively. The camera's E-TTL II autoflash and 12 exposure control modes (11 AE modes plus manual) are also unchanged from the EOS 30D SLR model. However, as a result of consumer input, Canon has added three Custom exposure modes. As an added convenience, particularly for wireless flash operations, users can adjust the flash settings of the Canon Speedlite 580EX II directly from the camera.

The Canon EOS 40D camera offers ISO speeds from ISO 100 to ISO 1600 in 1/3-stop increments. Users can also opt for a high-speed setting of ISO 3200. For the first time in any EOS camera, the 40D model offers Auto ISO capability in Creative Zone exposure modes. This valuable new feature adjusts the ISO speed to the optimal setting based on low light or shaky shooting conditions. Additionally, the EOS 40D provides full-time display of the active ISO speed setting, both in the viewfinder as well as on the top LCD data panel.

The Canon EOS 40D Digital SLR is also the first camera in its class to offer two interchangeable focusing screens in addition to the standard precision matte screen. Users can opt for a grid-type focus screen that makes it easier to verify horizontal or vertical alignment while determining image composition, as well as the Super-Precision Matte focusing screen that makes it easier to grasp the "sweet spot" of manual focusing when using a lens with a maximum aperture of f/2.8 or faster.

Enhanced Live View
Previously the province of the EOS-1D Mark III DSLR (one of Canon's top-tier professional cameras), the Live View function now gives EOS 40D camera users an expanded and exceedingly convenient and comfortable set of shooting options. By permitting the framing and capturing of subjects using the camera's LCD screen instead of the viewfinder, the shooter gains a 100 percent field view to more easily achieve the desired composition. A new Custom Function on the EOS 40D allows autofocus during Live View by pressing the camera's AF-ON button. At that point, the reflex mirror goes down and AF is carried out in the normal way. Letting go of the AF-ON button resumes Live View functions. Also, in the Live View shooting mode the user can magnify the image by five or ten times in order to ensure that the shot is optimally focused. Live View is at its best during tripod shooting – particularly for close-up photography where precise focusing is imperative. As a side benefit, the Live View shooting mode helps to reduce vibration by lifting the reflex mirror out of the optical path well in advance of the exposure, improving image quality at slow shutter speeds. A new electronic 1st-curtain shutter function in Live View mode reduces release time lag and operational noise even further to avoid spooking wildlife or disturbing people nearby with unwanted camera sounds. Additionally, as the release time lag is miniscule, even instantaneous movements like a bird taking flight can be readily captured.

EOS Integrated Cleaning System
First introduced on the EOS Digital Rebel XTi camera, the EOS Integrated Cleaning System is a prime example of trickle-up technology and is now becoming a standard feature on all new EOS Digital SLRs. The camera's Self-Cleaning Sensor Unit uses ultrasonic vibrations to literally shake dust particles off of the low-pass filter in front of the sensor each time the camera is powered up or shut down. Users also have the option of engaging the "clean now" function at will or bypassing it altogether. Additionally, the EOS 40D SLR's manual sensor cleaning function raises the mirror and allows users to clean dust that has stuck to the low-pass filter. Dust that has been shaken or blown loose is then trapped by adhesive at the base of the sensor unit housing, preventing the problematic particles from reattaching themselves to the filter when the camera moves. The second part of the cleaning system is a software solution that maps the location of any spots that may remain on the sensor. The mapped information is saved as Dust Delete Data and attached to the image file. Subsequently, the offending dust information is subtracted from the final image during post processing with a compatible personal computer, using the supplied Digital Photo Professional software.

Improved Software
Among the most valuable features of the Canon EOS 40D Digital SLR is its compatibility with Canon's Picture Style Editor (PSE) 1.0 software. With PSE, shooters can actually design the look of their photographs by inputting their own preferred style, color and tone curves. The EOS 40D Digital SLR also ships with the latest versions of Canon's powerful software applications, including Digital Photo Professional 3.1 and EOS Utility 2.1, which now support the camera's Remote Live View and Dust Delete Data functions, as well as incorporating a broad range of additional improvements designed to improve image quality and speed up workflow. Also included are ZoomBrowser EX 5.8 and ImageBrowser 5.8 for easy browsing, viewing, printing and archiving with compatible computer operating systems, including Microsoft Windows Vista and Windows XP, as well as Mac OS X.

Accessories
New system accessories for the EOS 40D SLR include the redesigned high-capacity Battery Grip BG-E2N, which facilitates high-volume shooting and easier vertical shooting. Compatible with up to two BP-511A battery packs or a set of six AA-size batteries, the battery grip approximately doubles the number of shots that can be taken, compared with the battery power of the EOS 40D SLR alone. The BG-E2N grip features new sealing material around the battery compartment to better resist water and dust. The new model replaces the original BG-E2 grip and is compatible with the EOS 20D, 30D and 40D models.

Designed exclusively for the EOS 40D SLR, the new Wireless File Transmitter WFT-E3A permits wireless transfer and back-up, as well as remote control of the camera in Live View mode. It can also be connected to various GPS receivers or Hi-Speed USB 2.0 external storage devices such as convenient flash drives or high-capacity hard drives with much larger storage capacity than the memory cards in the camera for instant back-up as images are captured. Compact and affordable, the WFT-E3A wireless transmitter also doubles as a vertical grip and requires its own BP-511A battery pack in addition to the battery installed in the camera body.

EF-S 18-55mm f/3.5-5.6 IS Lens
Developed in response to consumer demand for a high-quality yet affordable optically image stabilized lens, the Canon EF-S 18-55mm f/3.5-5.6 IS standard zoom lens adds a phenomenally flexible lens to the EOS 40D SLR shooter's imaging arsenal. While it features the wide-angle to mid-range zoom flexibility of its non-IS predecessor, this new EF-S 18-55mm f/3.5-5.6 IS lens offers the significant advantage of a true lens-shift image stabilization system that yields up to a full four stops of image-shake correction.

The higher performance provided by Canon's lens shift IS system (compared with the in-camera sensor shift type offered in some competitive SLRs) includes the ability to optimize the lens performance for specific shooting situations such as low-light, long-zoom or movement while shooting (or virtually any combination of the three). What's more, the shooter can see the image stabilization effect in the viewfinder. As the image already appears steady, more accurate framing and composition is possible, the AF point can be placed more precisely, and the photographer can concentrate on the optimal shot more comfortably.

Compact and lightweight, the optional EF-S 18-55mm f/3.5-5.6 IS zoom lens is manufactured by Canon specifically for the EOS 40D SLR and any other EOS SLR that takes EF-S lenses including the EOS 30D, EOS 20D, EOS 20Da, EOS Digital Rebel XTi, EOS Digital Rebel XT and the original EOS Digital Rebel camera.

Digital SLR Camera - Canon EOS 40D

The EOS 40D is the latest addition to Canon's line of mid-range, "prosumer" digital SLR cameras, which began with Canon EOS D30 in 2000. Announced in August 2007, the Canon EOS 40D, advances the state-of-the-art for digital SLR cameras specifically targeted at "advanced amateur photographers and entry-level professionals," according to the Canon press release on the EOS 40D digital SLR camera.

The Canon EOS 40D, featuring a maximum resolution of 10.1-megapixel through a CMOS imaging sensor and Canon's own advanced DIGIC III image processor, produces images of exceptional quality and clarity. An ideal blend of functionality and design, the EOS 40D digital SLR camera is also able to produce 6.5 frames-per-second in continuous shooting mode for bursts of up to 75 JPEG digital photographs. Canon has also completely redesigned the autofocus sensor, allowing for fast and precise AF control.

The Canon EOS 40D digital SLR camera has a 3.0 inch LCD display screen, compared with the 2.5 inch screen of its predecessor, the EOS 30D. The screen is also brighter for better visibility and faster menu controls. The viewfinder on the EOS 40D is also an improvement from Canon's previous cameras.

Outward appearances of the Canon EOS 40D digital SLR camera is similar to the previous cameras in the line but according to Canon, the EOS 40D's "magnesium alloy exterior even more ruggedly dependable than its predecessors with upgraded dust and weather resistant construction."

Awesome Tips that will help you with Digital Photography

by Dan Feildman

Over the past five years, the camera consumer trend has been to go digital. The development and use of Single Lens Reflex (SLR) digital cameras has grown dramatically, while there is a marked drop in the use of the historically traditional film cameras. While many remain faithful to the advantages of film technology, there is no denying that digital photography is going to capture the mainstream market. The increased quality in digital capture and memory capacity has been one alluring factor for digital photography. When digital cameras first came out, there was the question of whether to store the digital data files in RAW format or in compressed JPEG or TIFF files. Now many digital camera manufacturers provide instant storage of a RAW image at the same time a full-color JPEG is displayed for the photographer's immediate use.

There are a number of very inexpensive digital cameras available, but low resolution, unreliability, fixed memory, and often poor or inconsistent image quality plague the bottom of this segment. Avoid anything that has an unlisted resolution or a rating less than 2.1 Megapixels. Almost all brand-name low-end cameras have certain features in common with more expensive variants, such as shutter-release, red-eye reduction, and flash fill. If you anticipate the need for close-up photography, choose a camera with a "macro mode" and be prepared to work with available light or your own lighting - many low-end cameras disable their flash in macro mode, and even if they don't you may find that the flash causes more harm than good.

One interesting myth about digital photography is that digital cameras, with fewer moving parts, are somehow more durable than their film cousins. Digital cameras have as many (if not more) sensitive parts as film cameras. They share their most sensitive assembles, such as lenses. Digital cameras are often of lighter construction than film cameras. In short, there's no reason to treat any device roughly. Take care of your tools, and they will take care of you.

For most photographers, the vastly increased depth of field in digital cameras is good news. Too many pictures taken with our 35 mm cameras are not quite sufficient where they quickly run out of the depth of field. Digital provides a sharp foreground while enjoying details in the distance. This is especially evident in landscape photography. Being able to work with wide apertures (small F-stops) allows us to use higher shutter speeds, thus eliminating another source of image distortion. The program mode, especially for wide-angle lens settings, clearly favors wide apertures and high shutter speeds. Actually, small apertures, i.e., large F-numbers, may lead to image degradation due to diffraction effects. These factors depend on the actual (as opposed to relative) diameter of the lens aperture, which makes F-stops critical when programming digital cameras. This is one reason digital camera maker's limit themselves to F/8 or F/11, but not greater values, although these would be still quite useful in the macro mode. The camera lens, shutter speed and aperture play important roles in the quality of the photographs you take. They will determine how well you use the mega pixels you have to most accurately document your subjects.

If you stumble across the term "Shutter Lag", this is referring to the time it takes between pressing the button for a picture and the time it gets taken. Sometimes, the picture seems to take a pause in that time, and that is because of the shutter lag. You really only need to worry about this if you expect to be taking pictures of things that need a quicker or slower response time. For instance, you may want a faster shutter speed for action type pictures. If you are taking pictures of sleeping babies, it probably won't matter if there is a lapse in time. It is important that you ask questions about the camera you are buying. Most digital camera makers don't list the shutter speed of a camera. The best way to find out is to test it yourself, before you buy the camera. Also, many digital cameras have different "modes" of shooting, so that is a good way to control the shutter speed for many different conditions. If you need a versatile camera, get one that offers modes of shooting, instead of just manual.

If you want to capture incredible details and use less flash for night photos, then using a longer exposure time is the only way to go. If you are going to use a long exposure, make sure that you use a tripod, as any movement at all during the picture will cause the picture to become blurred. Also, you can capture some pretty cool effects, like car lights, when using a longer exposure. You will want to make sure that you know how to use and when to use your flash when taking a night picture, too. Most of the time, you probably will not even want to use your flash when you are taking a night photo. If youare taking a picture of an object, like a person, though, you will want to use your flash. When taking pictures of the night skyline, though, it is best to use a long exposure and take advantage of the natural lighting conditions. If you decide to take pictures at night, you will want to be able to control the photo as much as possible. Basically, you would take a shot of the area you want in your picture. Then, you take a picture of that same shot, only with the lens cap on. The reason for this is that at night, some of the pixels in the picture will not be visually good. When you take the picture with the lenses cap on, you will be recording the pixels again, while they are hot in your camera's memory. You can then use those pixels to repair the bad ones in the photo, with a photo editor. There are free photo editing software available online, but will not have some of the features of a professional photo editor.

If you are a picture-taking nut, then you probably love to share your work with others. When it comes to sharing digital pictures, there is nothing easier! Whether you have just taken another great picture of the new baby, or you have recently found an old photo that you know someone else would love, you can quickly share it with others. There are many ways to share a digital photo and there are just as many great reasons why you should! Why do you want to store your digital photos onto a CD or DVD? So that you can have them anytime you want, and so that you can print copies that you may need in the future. You can quickly slide the CD or DVD into a computer or any player you may have lying around. You can view the CD or DVD as a kind of slide show, if you want, and everyone can look at it at the same time; no more waiting to pass the pictures from person to person this way! You can also conveniently and effortlessly copy the CD's for anyone you want, if you have a CD or DVD burner, which are not really very expensive.

A Photographers Guide to Digital Camera Focus Modes

While some of the least expensive digital cameras have only automatic focus, meaning the camera does all the work on bringing your subject into the best possible focus, most SLR digitals offer three different focus modes manual, single auto focus and continuous auto focus. All three of these will be addressed here.

With manual focus, the camera stays out of the focus equation and you, the photographer, make all the decisions regarding this. This is done by setting different buttons or actually using an attached focusing ring that rotates on the camera lens. For those who like to have complete creative control of the finished product, this is the best focus mode.

In single auto focus mode, the camera automatically focuses when you press the shutter button either all the way down to shoot a photo or half way down to lock the focus. This mode is useful when shooting static objects.

In continuous auto focus the camera continuously focuses on the objects in the photo. In this mode the camera continuously corrects the focus as the objects distance from the camera changes. This mode is useful when you shoot photos of moving objects such as a race car during a race or airplanes during an air show. You can hold the shutter button half way down and continuously move the camera to follow the object. The camera will continuously keep the object in focus.

Like any other feature automatic and manual focus modes have their pros and cons. The first step to using them to your advantage is to understand how they work and what they were designed for. The next step is to experiment shoot photos using different focus modes and different types of objects and see how the camera behaves. Once you have done that you will be ready to instinctively use the best focus mode for each photo situation.

Artistic Digital Photography

In time, photography experts have tried to revolutionize the ever growing popularity of the digital age. In fact, nowadays, many who consider themselves true photographers still prefer manual cameras with traditional film over the digital camera. Nevertheless, an increasing number of artists have perfectly realized that the new technology of today can also be used to create art in a new way in addition to some other practical purposes. This is a way that would not be available if not for our digital age.

Of course, artistic digital photography, like traditional photographic art, takes a special kind of camera. That is not to say that amateurs cannot create art with a standard point and shoot digital camera, but rather, that those who are serious about digital photography as an art form prefer a specific type of camera: the digital single-lens reflex or dSLR. A dSLR is really nothing more than a duplication of the traditional manual version, the SLR. It operates on the same principles, with one obvious difference: a SLR would have film; whereas a dSLR has what is called an image sensor called a CCD or CMOS.

But what makes dSLR's and SLR's different from other cameras in general? Well, a traditional camera makes use of an off axis viewfinder (mounted above or to the side of the actual image the lens "sees") that can distort the image you see and want to capture, creating what is called "parallax". With an SLR, this is remedied by using an internal prism to project the same image seen in the lens up and onto the viewfinder, by passing the parallax distortion that occurs in other cameras.

Since artists have generally preferred the accuracy of SLR's, the inception and growing adoption of their digital counterparts has made artistic digital photography spark from an ember to a roaring bonfire of popularity. Because of the manual functionality inherent in most models and the speed, a dSLR camera is preferred by many over a digital camera. Enough with the technical banter. Put simply, as digital cameras swiftly become faster and allow higher resolution, their following in the artistic world grows. In fact, at this point in time, digital cameras are even beginning to surpass their manual predecessors, something that some traditional photographers can scarcely believe to be true.

Of course, digital photography does have its downsides when compared to traditional film, but it also has its perks. The digital side actually has greater technological advantages than what many believe. With digital image filters, special processors and incredibly powerful computer based editing tools, an artist can truly make pixels come alive in a whole new way with digital photography. With traditional film, an artist must spend hours in a darkroom, processing film and mixing chemicals in order to turn out the print that they are looking for.

With digital film editing tools, the need for the complex development process is all but gone: a digital photographer need only upload his images to a computer and he is then free to edit them to his hearts content: complex processes such as cropping, light filters, rotating, highlighting, color spectrum adjustments, and layering can all be done with the click of a mouse.

Whether you are an amateur photographer who wants to make the most of their hobby or a professional artist who needs control, speed and accuracy as well as editing ability, artistic digital photography can turn simple images on an internal processor into stunning, compelling art. So what are you waiting for? Get that freedom and power from digital photography and start creating the art that you've always wanted.

Digital SLR Cameras - Body and Lenses

By: Jacob Georgeson

Digital SLR cameras are usually sold in two parts: the camera body and lenses. There are many types of lenses with different characteristics from macro to zoom, with special options like image stabilizers, special filters and more. In this article you will read about some lenses options and what you should consider when buying them.

You can and should own more than one lens. Different lenses are better at different scenes. An obvious example is the difference between a macro lens used to take shots of objects from a very short distance sometimes almost touching the camera and zoom lenses designed to take photos from a far distance. Professional photographer always carry a few lenses with them and change the lens often in order to use the right one for each photo shot. Sometimes professional photographer actually carry a few cameras with different lenses mounted on them allowing them to quickly choose the perfect lens for each shot without the need to actually switch lenses back and forth.

Some lenses also provide special features that better the photos taken. For example, image stabilization, also known for short as IS, eliminates the effect of small camera movements as the pictures is taken. Such movements are a problem in extreme cases for example when shutter speed is low in low light scenes or when using a high zoom lens taking photos from far away. In those cases every small camera movement translates to blurry digital photos. The image stabilizer (IS) is an optical electro-mechanical mechanism. Using a gyro and a floating optical element the image stabilizer senses camera movements and moves the optical element in right direction and distance to compensate for such movements.

If you need to take photos of objects from a very short distance you should consider purchasing macro lenses. Macro lenses enable the digital camera to be positioned very close to the object sometimes almost touching the object and still sharply focus on it. Common objects that photographers experiment with when using macro lenses are insects, leaves, screws, nails, bolts and more. Another challenge with macro photography is lighting. If you need to use a flash any normal flash would emit light that is too intense just because the object is closer to the camera than the focus was designed for. You can either use a flash that allows setting for such a distance or place a filter on the lens.

If you plan to use really long zoom lenses you should consider lenses that support special tripod mounts. Cameras with very long lenses are heavy and their gravity center shifts out toward the lens. In order to stabilize a camera with such lenses a special tripod attached to the lens is needed. When buying such lenses it is recommended to make sure that such a tripod can be used with the lens and if you already own a tripod that the mounting mechanism is compatible with the lens.

When buying lenses you should also take into consideration their planned usage. Tow lenses can have the same optical characteristics but for example very different weights just because they are made from different materials. If you plan to travel and carry the lens weight is important even at the cost of a higher lens price.

For more information on the different types of photography zoom lens available, read this article.

The movement of the lens for focusing purposes is internal to the lens body, so no lens ring will cause the lens to twist out and interfere with the orientation of any filters. (Some filters, such as linear polarizers or graduated neutral-density filters require stationary positioning in order to deliver predictable results.) This internal movement also allows the lens weight to stay balanced, which helps the balancing of heavier lenses on a tripod. Image quality of newer IF lenses is slightly better than non-IF lenses due to technological advances made that correct some aberrations.

Image Stabilization (IS) or Vibration Reduction (VR)
Most types of lenses above come in two flavours: either with image stabilization, or without. Built-in stabilization allows you to get sharp hand-held images when lighting conditions are poor, or you're shooting from a moving vehicle. On the lenses that offer this capability, there is usually a switch that lets you turn the feature off, thus saving batteries when using a tripod. Beware the cost of these lenses, though: you can expect to pay 2-4 times as much for a lens with image stabilization than the same lens without.

Constant vs Variable Aperture
Variable aperture accounts for the majority of zoom lenses, and causes the maximum aperture to decrease as you zoom from wider focal lengths to telephoto focal lengths. The advantage of variable aperture zoom lenses is that they're cheaper to maufacture and are typically lighter and more compact than contact aperture lenses.

Constant aperture lenses provide a static maximum aperture regardless of the focal length you're zoomed to. This better enables you to achieve narrow depth of field so as to isolate your subject from your background. These lenses typically let more light in, which lets you shoot sharp photos in dimmer lighting conditions.

Macro Focusing
Macro lenses allow the camera to be very close to its subject and still focus sharply. Macro lenses are ideal for close-up shots of flowers, leaves or insects, and sometimes double as portrait lenses. They typically have a reproduction ratio of 1:4 or better, which means the image sensor will capture the subject at 1/4 its original size or larger.

Low-Dispersion Glass
Some lenses are made with high-quality glass specially manufactured to more accurately transmit the full visible colour spectrum, called low-dispersion glass. You may also hear of ED (extra-low dispersion), SLD (super-low dispersion) or UD (ultra-low dispersion), which really just means truer colours.

Apochromatic Lenses (APO)
Apochromatic lenses have high colour fidelity and sharpness and should be used by anyone obsessed with getting to the most accurate colours possible.

Aspherical Elements (ASP)
Aspherical lenses are made with a different curvature than traditional spherical lenses to correct for distortions at the edge of the image. They are particularly useful in wide-angle lenses where vignetting or distortion can be seen in the corners of the image.

Tripod Mounts for Long Lenses
Lenses that are bigger and heavier than your camera body should have a tripod mount built-in. By attaching the lens to the tripod instead of the camera, you will remove tension on the camera-to-lens mount joint, and you will improve tripod balancing in the field. In fact, without a tripod mount, some larger lenses will cause the tripod to topple, thus making tripod use impossible without a lens mount. It is possible to purchase a separate adapter bracket from some manufacturers if the lens itself does not have one.

Plastic Material vs Alloys
Plastic lenses built recently typically use high-tech materials that are very durable and much lighter than metal alloy lenses. So although it used to be said that plastic lenses are cheap and unreliable, that is no longer true today.

Size
Zoom and telephoto lenses are getting smaller and lighter each year. In general, the larger the focal length of the lens, the larger the lens will be physically.

Weight
The heaviness of a lens may be prohibitive to you, depending on your physical fitness level and how long you'll be away from home. Plastic lenses are quite durable and are definitely lighter than equivalent metal lenses, although ultra-lightweight metal alloys are reasonable as well.

Price
In general, no matter which lens you're looking at, prices vary dramatically based on lens quality. Professional lenses will cost you thousands of dollars, while a compact modest starter zoom lens will be only a hundred dollars. You'll pay extra for some of the characteristics discussed in this article, such as fast constant apertures, high quality glass, image stabilization, and quick auto-focus. Remember, though, that lens price is a large investment: lenses will long outlast your camera body, and is largely responsible for the quality of your images (much more so than the camera body itself)!

Zoom Lenses for your SLR camera

By: Jennifer Clarkson

When you own a Single Lens Reflex (SLR) camera, you have the option of purchasing more than one lens for various purposes. Zoom lenses and prime lenses are something that every SLR owner should have. Let's look at the definition for each.

Prime lenses are those with a fixed focal length, such that zoom is not possible. That means that if you wanted to have your subject appear larger in your frame, you would have to physically move your camera closer to the subject instead of zooming closer with the lens itself. Prime lenses are faster at focusing than zoom lenses, but are typically used for static scenes, such as macro photography or portrait photography.

Zoom lenses allow you to make your subject larger in the frame without physically moving your camera closer. This article explores the different types of zoom lenses out there and offers recommendations for what suits your style of photography - macro, landscape, wildlife, sports. We'll look at autofocusing zoom lenses and manual focus zoom lenses. Also check out this related article about Camera Lens Characteristics.

Autofocusing Zoom Lenses

1) Ultra Wide-Angle Zoom Lens

Typical focal lengths: some range between 17-35mm (e.g. 20-35mm, 17-28mm, 17-35mm)
Characteristics: The angle of view is quite wide, around 170 degrees from the camera. The depth of field is large, so foreground and background will be in sharp focus all at once.
Uses: landscape photography

2) Wide-Angle To Moderate Telephoto Zoom Lens
Typical focal lengths: some range between 24-105mm (e.g. 24-85mm, 28-105mm, 35-80mm)
Characteristics: Typically the first type of lens you purchase with your SLR. These lenses provide the range needed for most shooting situations, aside from specialty photography. Their weight is light, and their size is compact, so these are usually the easiest lenses to travel with when you only want to take one lens.
Uses: travel photography, landscape photography

3) Mid-Range Telephoto Zoom Lens
Typical focal lengths: some range between 50-300mm (e.g. 70-200mm)
Characteristics: These lenses are slightly larger than the category above, but are still fairly compact. They are better for photographers who typically want a telephoto shot from a distance. They best compliment a wide-angle zoom and a telephoto zoom together to cover most focal lengths.
Uses: wildlife photography

4) Telephoto Zoom Lens
Typical focal lengths: some range between 100-300mm (e.g. 70-200mm)
Characteristics: These lenses offer high magnification, allowing you to get up close to dangerous or distant subjects while keeping your distance. Depth of field can be small with these lenses, which allows you to isolate your subject from its background.
Uses: sports photography, wildlife photography

5) Big-Range Zoom Lens
Typical focal lengths: some range between 100-500mm (e.g. 35-350mm, 50-500mm)
Characteristics: These large and heavy lenses offer high quality images with subjects very far away. They are much more affordable than they used to be, but likely don't fit in an average camera bag, and are much heavier than your camera. They typically come with a tripod attachment, such that you can attach the lens to tripod instead of the camera body to achieve centre of balance.
Uses: wildlife photography


Manual Focus Zoom Lenses

6) Ultra-Telephoto Zoom Lens
Typical focal lengths: some range between 100-600mm (e.g. 400-600mm)
Characteristics: These large and heavy lenses offer high quality images with subjects even further away than big-range zoom lenses. They allow rapid manual focusing while tracking a subject.
Uses: wildlife photography

Full Review - Nikon D40x Digital SLR Camera

Nikon's entry-level digital SLR is its most compact SLR camera ever, featuring a 10.2 megapixel CCD and a 2.5 inch LCD screen for crisp, high-resolution photographs and intuitive controls.

Nikon Corporation announces the D40X, a new digital SLR camera incorporating a 10.2-megapixel CCD.

While maintaining the compact size and external features of the D40 camera body, the Nikon D40X produces even more outstanding, detailed photos thanks to its 10.2-megapixel CCD and the latest digital technologies. Its resolution power makes it easy for users to print up very large sizes or crop aggressively without having to lose any fine details in their digital photographs. The D40X is loaded with everything you need for truly amazing images: a 10.2-megapixel CCD, Nikon’s exclusive 3D Color Matrix Metering II, an improved Image Processing Engine and superb Auto White Balance. Together with a world-famous Nikkor lens, these features combine to ensure stunning photography with perfect exposure, refined details and natural, vivid colors.

The D40X shares the D40’s ergonomic design and streamlined interface, which means the same intuitive operation that’s simple and fun – even for entry-level photographers. The bright and clear viewfinder ensures precise composition, while the 2.5-inch large LCD monitor utilizes an easy-to-use menu system and a wide viewing angle so that every photographer can navigate their settings and view their images with ease. There is also a handy built-in Help menu: simply press a button and useful information on key features is displayed on the LCD monitor.

The D40X is fast. Its near-instant power-up (0.18 second) and fast, reliable responses help photographers act on the moment, while the continuous shooting mode lets photographers easily capture up to 100 JPEG images of action as fast as 3 frames per second. The camera’s razor-sharp autofocus ensures crisp digital photographs for a wide variety of photographic scenes.

Flash photography is simple with the D40X because the camera employs Nikon’s market-leading i-TTL flash control, which evaluates ideal flash exposure automatically and accurately, even in difficult lighting situations.

Eight Digital Vari-Program modes offer creative shooting options that are optimized for common shooting situations. Fun, fast and simple, they are as easy to use as rotating the mode dial. For further control over aperture and shutter speed, P/S/A/M modes are available.

Exclusive in-camera image editing features are available in the Retouch menu. One of the main features is Nikon’s exceptional D-lighting, which brings out details usually lost in underexposed areas of an image while retaining the proper exposure in brighter areas. Photographers can also correct red-eye easily, or use Monochrome effects to change an image to Black-and-white, Sepia tone or Cyanotype.

Some of the D40X’s major digital photography improvements include an even longer-lasting battery that allows up to 520 images per charge (470 images for the D40), faster continuous shooting at 3 frames per second (2.5 fps for the D40) and a wider ISO sensitivity of 100 to 1600, plus HI 1 (200 to 1600 plus HI 1 for the D40).

While it inherits many advanced digital photography and optical technologies from professional models, the D40X and its sister model, the D40, are Nikon’s smallest, most compact digital SLR cameras. By offering everyone mobility, ease-of-use and incredible photos with great resolution, the D40X welcomes everyone to the world of Nikon digital SLR photography.
