Examples
Open these from Help › Examples…, or from the ? menu in this node's Properties panel.
- ColorCorrect by tonal range (
examples/color/colorcorrect_ranges.oink): ColorCorrect adjusts shadows, midtones and highlights separately. Here the shadows get cooler and less saturated, the highlights warmer, and the whole image a bit more contrast.
