### Gamma Correction

Printer paper, ink, resolution, and other characteristics can cause the actual printed color to be different from the desired color. This "skew" is non-linear and occurs over the entire color spectrum. A gamma-compensation curve is used for each color to approximate the non-linear skew. Because the reflected frequencies of colors can cause them to appear different than expected, you can modify the gamma of each color. Increasing the gamma will lighten an image that might otherwise look too dark.

Following are the gamma functions:
