Photography 101: Basic Composition

Basic information about the rules of composition in digital photography. Composition turns digital photography into an art.

by Kelly Paal

Now that you are beginning to understand how your camera works you can begin to understand basic composition in digital photography. I know that many people that I’ve talked to think that digital photography is just pointing your camera and taking a photo but it’s more than that. After you understand how your equipment works you can begin to get into the real art of digital photography and that art is called composition.

Basic Principles

1. Use all of your available space. Fill the image with the image. If the reason that your taking the photo is your daughter’s beautiful face then get closer. If you’re taking an image of the breathtaking valley before you. Fill the frame with the valley. Keep distractions out of the frame. They’re called distractions for a reason.


2. Look at the forms in your image. You almost have to look at the people or the landscape before you in their simplistic geographic forms. A good way to learn form is to practice taking photos of still life objects, that you can arrange into pleasing forms. A good digital photograph is always a beautiful arrangement of form. Whether it’s the beauty of a woman’s face, her features being forms, or a wonderful landscape, trees, rocks, and hills being forms.


3. Line or direction, motion. The direction of the forms in your photos is very important. Never have action or motion moving outside of your digital photograph. It will direct the eye away from your image. Diagonal motion lines are good, curves and “s” curves are better. The last two is probably way landscape photography is so popular nature is full of curves. Also never put a horizon line in the center of your frame.


4. Contrast, the difference between black and white. Now it is possible to have a beautiful photo with little contrast if that is your intention, this works best with color. But a lot of shots, some really beautiful shots have a nice balance of black, white, and grays. This can be manipulated for artistic purpose of course, but in the beginning you want to focus on trying to take digital photographs with equal amounts of black, white, and shades of gray.
   


5. Color, you may have to familiarize yourself with the color wheel. Whether you’re shooting nature or setting up your own shots in a studio you need to know what colors go together and why. Many of us have an instinct as to what looks good. When in doubt follow your instincts. Start out by taking shots of things that you think have pretty or beautiful colors. Show the photos to others and see if they agree. Digital photographers learn not only what they think is beautiful but what is universally beautiful as well.

Now the hard part practice all these principles at the same time. It’s not easy! Now you really know why digital photographers take years to really learn their craft.

Photography 101: White Balance Demystified

White balance is a very important concept in digital photography, and involves the process of measuring light and colors. Understanding how it works will allow you to do wonders with your digital photography.

by Jennifer Clarkson

The term “white balance” originates from the world of video imaging where a device (waveform monitor) was used to match or “balance” the signals from the camera’s red, green, and blue channels to make accurate whites under various lighting conditions, thus balancing your white. In this article, we’ll use “white balance” for digital cameras in a similar sense: the process of measuring your light source’s color temperature accurately, based on your lighting conditions, and using that information to correctly balance your whites and colors.

Symptoms of Poorly Set White Balance
If your digital camera’s white balance is set incorrectly, or if your digital camera chose the wrong algorithm for measuring color temperature, then you will observe a color cast on your digital photo: it will either look slightly blue, slightly orange, or slightly green. A low color temperature shifts light toward the red; a high color temperature shifts light toward the blue. Different light sources emit light at different color temperatures, and thus the color cast. Let’s take a look.

What is Color Temperature and How Is It Measured?
Color temperature is effectively the warmth that is emitted from a light source, and the effect that temperature has on the intensity of any particular color in the visible spectrum. For example, a 200 W bulb has more intensity in the orange/red end, and shows purples and blues with very little intensity. This makes your photo appear “warm”. Daylight has equivalent intensity across the whole spectrum, so you see purples and blues with the same intensity as oranges and reds. But shade or a heavily overcast sky has more intensity in the blue/purple end, so your oranges and reds will have very little intensity. This makes your photo appear “cool”.

Here are some examples of color temperatures from common light sources:
1500 K: candle light
2800 K: 60 W bulb
3200 K: sunrise and sunset (will be affected by smog)
3400 K: tungsten lamp (ordinary household bulb)
4000-5000 K: cool white fluorescent bulbs
5200 K: bright midday sun
5600 K: electronic photo flash.
6500 K: heavily overcast sky
10000-15000 K: deep blue clear sky

Newer light sources, such as fluorescent and other artificial lighting, require further white balance adjustments since they can make your photos appear either green or magenta.

How Does a Digital Camera Auto-Detect White Balance?
Your digital camera searches for a reference point in your scene that represents white. It will then calculate all the other colors based on this white point and the known color spectrum. The data measured from its R G B sensors is then run through a whole lot of numbers and predetermined equations to figure out which white balance setting is most likely to be correct. Remember, white balance is the automatic adjustment that makes sure the white color humans observe will also appear white in the image.

Setting your digital camera’s white balance to auto white balance (AWB) will provide color accuracy under many conditions. Your digital camera will adjust the white balance between 4000K – 7000K using a best guess algorithm. Auto white balance is a good choice for situations where the light changes over time and speed is an issue (e.g. animal photography, sports photography). However, you should avoid using auto white balance settings in the following situations:

1. Your scene is heavily dominated by one color
2. Color accuracy is absolutely imperative
3. You are photographing particularly warm or cool scenes (e.g. a sunset)

White Balance Presets
Most digital cameras come with multiple white balance preset options. These presets work well when:

1. The light source matches one of the preset white balance options
2. Your scene is heavily dominated by one color

Common Preset Options:

• Tungsten - "Tungsten" is the name of the metal out of which the bulb's filament is made. The color temperature of this setting is fixed at 3,000K. Best Use: indoors at night. Otherwise, your exposure will turn out too blue. Creative Use: Set your exposure compensation to -1 or -2 and use this setting in daylight to simulate night.


• Fluorescent - The color temperature of this setting is fixed at 4,200K. Best use: Fluorescent, mercury, HMI and metal halide lights used in your garage, sports stadiums and parking lots. Otherwise, your exposure will turn out too purple.


• Daylight - The color temperature of this setting is fixed at 5,200K. Best use: studio strobe lights. Otherwise, your exposure may have a slight bluish tinge.


• Cloudy - The color temperature of this setting is fixed at 6,000K. Best use: direct sunlight and overcast light. This setting will warm your photo by giving it an orange tinge, which is often desirable in landscapes and portraits. Creative Use: sunsets.


• Shade - The color temperature of this setting ranges from 7,000K - 8,000K. Best use: shooting in shade, no direct sunlight (cloudy), backlit subjects. Otherwise, your exposure will turn out too orange. Creative Use: direct sunlight – it will warm up your photos even more!


• Flash - The color temperature of this setting is fixed at 5,400K. This is almost identical to Cloudy but sometimes redder depending on the camera. Best use: overcast skies. Otherwise, your exposure will turn out too red.
