Gamma
Adjusts the image’s midtone values without affecting black and white levels. This causes changes in contrast,
much like changing the shape the curve in the Luma Curve effect. Use this control to adjust images that are too dark
or too light, without distorting shadows and highlights.
Pedestal
Adjusts an image by adding a fixed offset to the image’s pixel values. Use this control with the Gain control
to increase an image’s overall brightness.
Gain
Affects the overall contrast ratio of an image by adjusting brightness values by multiplication. The lighter pixels
are affected more than darker pixels.
