A collection of Python plugins for GIMP.

These are tested/used with version 2.10.

To install, copy them into the correct location for your user. For example:

cp foo.py ~/.config/GIMP/2.10/plug-ins

Make sure that they are executable!

Also, be sure to restart GIMP after installing any plugins. There is no "refresh scripts" option that works for Python plugins.

When editing GIMP plugins, it may be preferable to have a symbolic link from your GIMP plugin folder to the source file in your git repo. The reason is that testing the script requires that it be installed, and it is highly unlikely that your plugin folder is a repo. Using symbolic links lets you edit/commit/stash, etc., while keeping the plugin installed.

Filters -> Generic -> Luminosity mask setup

This script automates the procedure laid out in this tutorial and in this video.

Any resizing, etc., of the image should be applied prior to running this script.

The final result is three layer groups (darks, lights, and mid-tones).

This plugin can consume a lot of RAM on big images!

This script is similar in scope to one by Pat David avaiable here. His script works via a different set of operations resulting in the same masks. The major difference is that his does not group them as layer masks in layer groups.
