Gamma
The relationship between a computer's inputs and the brightness or luminance displayed on a monitor. Gamma is expressed in the following equation: Brightness (Luminance) = Constant x inputgamma. While gamma has no effect on black or white, it does affect gray or midtones. If a monitor's gamma level is set too high, midtones will appear too dark. Conversely, if gamma is set too low, midtones will appear too light.
