*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.
