About White Balance
The three RGB (red, green, and blue) primary colors exist in the light source in
varying proportions depending on the color temperature. When the color
temperature is high, there is more blue. And when the color temperature is low,
there is more red. To the human eye, a white object looks white regardless of
the type of lighting. With a digital camera, the color temperature can be
adjusted with software so that the colors in the image look more natural. The
subject's white color is used as the criteria for adjusting the other colors. The
camera's < Q > setting uses the CMOS sensor for auto white balance.
