Shadow highlight
Last updated
Shadow highlight is a Colour effect.
What it does
Section titled “What it does”The effect lifts dark regions of a picture, and can pull bright regions down.
Whether a pixel counts as a shadow or highlight is based on how bright its surroundings are, and not just its own brightness.
