Gamma Correction

Example: "The photographer applied gamma correction to his display to enhance the contrast of his photos."

Gamma Correction Image

Gamma correction is used to alter the output levels of a display. Since the standard input signal (or voltage level) is not high enough to create a bright picture, gamma correction is used to boost the brightness and contrast of the display. PCs typically use a gamma setting of 2.2, while Macs have a default gamma setting of 1.8. Some systems include a display utility that can be used to apply custom gamma settings.
