The range selection script is a tool for easy and automatic creation of selections and lay­er masks. The selections or masks include all parts of the image that are situated within a defined range of tonal values, colours, saturation or edges. Selections can be based on one of 16 channels. For detailed instructions and several samples have a look at the attached manual.

Lomo-Gimp tries to give your digital pictures the warmth of those taken by an old rangefinder analog camera. Think of it as a Kodak Instamatic or a Lomo Holga faking effect. It enhances contrast and saturation, and applies a light and a dark overlay, trying to emulate incorrectness in exposition. Please note this does nothing to emulate the chromatic aberration peculiar in pictures taken using a real Lomo.

This is another script for converting a picture to black & white. The decompose plugin must to be available. The way of converting the picture is rather different than what other plugins do.

This script allows you to extract and apply saturation to a layer. When you extract, it adds a new layer with the saturation values (in gray colors). You can then use curves, brightness/contrast or the dodge tool to correct saturation. When you are okay with the adjustements you can put back the saturation by applying it.

It installs itself in < script-fu >/Saturation.

Comments inside the script are in french.
