overview of OpenGL Gamma correction Gamma correction Gamma correction is used to alter hardware colormaps to compensate for the non-linearities in the phosphor brightness of monitors. Gamma correction can be used to improve the "ropy" or modulated appearance of antialiased lines. Gamma correction is also used to improve the appearance of shaded graphics images, as well as scanned photographic images that have not already been gamma corrected. 18 Chapter 1

Gamma correction
Gamma correction is used to alter hardware colormaps to compensate
for the non-linearities in the phosphor brightness of monitors. Gamma
correction can be used to improve the “ropy” or modulated appearance of
antialiased lines. Gamma correction is also used to improve the
appearance of shaded graphics images, as well as scanned photographic
images that have not already been gamma corrected.
