White Balance
Whatever the kind of the light, the human eye adapts to it so that a white object still looks white. On the other hand, devices
such as digital cameras see a white subject as white by first adjusting the color balance to suit the color of the ambient light
around the subject. This adjustment is called matching the white balance.
