G’MIC CLUT from After Before Layers node

This documentation is for version 1.0 of G’MIC CLUT from After Before Layers (eu.gmic.CLUTfromAfterBeforeLayers).

Description

What is this filter for?

This filter requires at least two input layers to work properly.

It assumes you have an input top layer A and a base layer B such that A and B both represent the same image but with only color variations (typically A has been obtained from B using the color curves tool).

This filter is then able to estimate and outputs a color HaldCLUT H so that applying H on the base layer B gives back A.

This is useful when you have a color transformation between two images, that you want to recover and re-apply on a bunch of other images.
