white balance

The process of adjusting the video camera s red, blue, and green Gain controls in order to balance the color of prevailing sources (sunlight, sky light, fluorescent, etc.). White Balance is performed instead of, or in addition to, using internal or external camera filters or colored gels on the lights. Tips: For normal results, balance is done on a pure white card using the same light that falls on the Subject. In order to achieve abnormal color you can trick the camera by white balancing on a card or paper exactly opposite from the color desired. Some pros keep an assortment of colored cards handy for this off-white-balance operation. Also see: Auto White Balance and Color Distortion.

white balance

A digital camera analyzes a scene using its white balance mode to determine areas that should be recorded as pure white. The camera adjusts the overall scene s color balance so that the areas meant to be reproduced as white in the picture will be white, thereby also adjusting all the other colors in the scene using the same color shift values, so that all color is accurately represented. A digital photographer can usually set the white balance to suit the color temperature of the light falling on the subject. Some cameras can automatically set white balance.
