Function
The RGBL command controls balance for each level of RGB. It individually corrects the
gamma for each color.
The color bars below represent color balance variations for each of RGB. The top bar
represents the default saturation variation. The output result for an input value is
maintained in linear form. The middle color bar is an example showing an increase in
output for the input value. Indicates γ > 1.0 when being equivalent to the gamma curve.
The bottom color bar is an example showing a decrease in output for the input value.
Indicates γ < 1.0 when being equivalent to the gamma curve.
Varying color balance allows the output image results to vary. Issuing this command
resets h
ue, saturation, and luminosity control values to their default settings.
