Quest#1. What is white balancing a camera, why do you do it, and what does it accomplish?

White balance (WB) is the process of removing unrealistic color casts, so that objects which appear white in person are rendered white in your photo. The camera attempts to determine the color temperature of the light and automatically adjust for that color temperature. The reason we adjust white balance is to get the colors in your images as accurate as possible.
