White Balance – Manual
This slider will adjust the White Balance. White Balance is the adjustment of
an image to calibrate it so that a white object appears white on the video
monitor. This adjustment is done by varying the Red, Green and Blue levels
of a video image. Commonly Green is a fixed value, and Red and Blue are
adjusted.
