ColorCorrect node¶
This documentation is for version 2.1 of ColorCorrect (net.sf.openfx.ColorCorrectPlugin).
Description¶
Adjusts the saturation, contrast, gamma, gain and offset of an image.
The ranges of the shadows, midtones and highlights are controlled by the curves in the “Ranges” tab.
The Contrast adjustment works using the formula: Output = (Input/0.18)^Contrast*0.18.
