gamma gamma-corrects a particular image channel.
The same image viewed on different devices will have perceptual
differences in the way the image's intensities are represented
on the screen. Specify individual gamma levels for the red,
green, and blue channels, or adjust all three with the gamma
function. Values typically range from 0.8 to 2.3.
You can also reduce the influence of a particular channel
with a gamma value of 0.
