WebGamma correction is the practice of applying the inverse of the monitor transformation to the image pixels before they're displayed. That is, if we raise pixel values to the power 1/ gamma before display, then the display implicitly raising to the power gamma will exactly cancel it out, resulting, overall, in a linear response (see Figure 24-2 ). WebSince gamma correction generally occurs automatically, users usually obtain correct color handling on a PC monitor without much effort. However, the precision of gamma correction varies from manufacturer to …
