Adjustments : Levels and Gamma
 

Levels and Gamma

Levels and Gamma can be used to alter the color range (exposure) of an image, including gamma adjustments, on a channel-by-channel basis. Most adjustments performed using levels consist of changing a pictures input and output white-point, black-point, and grey-point.

The gamma bias can also be adjusted, this is done by manipulating the grey point of the image.
