Color Correction
Use to change the brightness, contrast, hue, saturation, and gamma properties for a selection or the entire can-
vas.
The following graphic shows a sample of the following effects:
1. Original capture.
2. Brightness: Lighten or darken the entire image.
3. Contrast: Change the contrast between the light and dark colors.
4. Hue: Change is similar to rotating a color wheel to select a different mixture of colors.
5. Saturation: The quantity of a color in pixels, from gray at the lowest saturation to rich color in the high-
est.
6. Gamma: Adjust the intensity of colors by changing the gamma constant used to map the intensity
values. Gamma correction changes brightness using a logarithmic scale for visual perception. Gamma
is a constant used to calculate the progression. For most CRTs, the gamma constant is in the range of
2.2 to 2.5.
