Digital Literacy Concepts: White Balance

Information about concepts related to digital literacy.

White Balance

Sources of light vary in degrees of color temperature. For example, fluorescent lights are cooler and green, while incandescent lights are warmer and orange. The color of an object will reflect these cooler and warmer tones when viewed under different light sources. The chart below shows the color temperature of different light sources in degrees Kelvin (K).

Scale of light and temperatures

The human brain naturally processes these differences in color temperature to keep a “white” object appearing white to our eyes under different lighting conditions. However, digital cameras need to be told what “white” looks like under different sources of light. In the camera's white balance menu, you’ll find preset adjustments that add warmer or cooler tones to your image. Here is a list of these presets and what kind of tone they add to the image.

Adjusting White Balance

You can use the camera’s preset options to adjust the color temperature of your image. For example, the image below moves from a cooler tungsten preset, to a neutral automatic white balance setting, to a warmer cloudy preset.

Examples of different white balances

The auto white balance setting gives a fairly accurate representation of white in the image. However, you may want to use manual settings to achieve the most accuracy. See our camera equipment guides for instructions to configure your manual white balance.
