This note details the treatment of gamma correction on Apple Macintosh (tm) computers. Gamma correction is the process of precompensating for the nonlinear voltage-to-light intensity function of the CRT of a video monitor or a computer monitor, in order to obtain correct reproduction of intensity. Gamma correction is important if you want to obtain good picture quality and accurate color reproduction.
