Appendix E

White balance

The human eye is able to adapt to changes in lighting, and consequently to humans a white

object will still look white whether viewed in direct sunlight or under overcast skies, or indoors

under incandescent or ﬂ uorescent lighting. A digital camera, in contrast, must adjust colors

according to lighting if colors that appear white when viewed directly are also to appear white

in the ﬁ nal photograph. This adjustment is called “white balance.”

White point

The input value above which all input tones are mapped to the maximum output value (the

default for the master channel is white). Any details brighter than the white point will be lost.
