White Balance
Ron Bigelow (via Erik Barzeski):
To create an image that accurately depicts what the photographer intended, the photographer must be aware of the color of light and must make adjustments when necessary. The subject of the color of light, and the techniques of dealing with it, are referred to as white balance—the subject of this article. The tools and techniques that photographers use to deal with white balance will be covered at the conceptual level. The actual implementation of these tools and techniques vary from camera to camera and are beyond the scope of this article. It is left up to the photographer to look up the instructions in his camera manual.
