Gamma

Gam m a
NOTE: This is the same as "Gamma" in the Image Settings Menu.
"Gamma" determines how gray shades are displayed between minimum input (black)
and maximum input (white) for a given amount of signal. The proper setting helps
maintain optimized blacks and whites while ensuring a smooth transition for the "in-
between" values utilized in grays. Unlike brightness and contrast controls, the overall
tone of an image can be lightened or darkened without changing the two extremes
and your images will be more vibrant yet with good detail in dark areas when using
the Gamma control.
The normal gamma setting of 2.2 is correct for most signals and conditions. If excess
ambient light washes out the image and it becomes difficult or impossible to see
details in dark areas, lower the gamma setting to compensate. This will improve
contrast ratio while maintaining good details for blacks and whites.
