Batch Edit Color Balance, Brightness and Contrast

The script enables you to do two image adjustment operations to all images in a folder:

  1. Individually adjust the color balance in shadows, midtones and highlights
  2. Adjusting the Brightness and Contrast

You choose a folder with a folder browsing widget, you can also specify the file extension of the files you would want to change(useful if you have non supported files in the same folder).

Colour-match Win32 binary

Windows binary for this new plugin by Arel Welgan.

Source has been fixed for Windows compilation by Samj. Plugin no longer crashes under Windows.

Please note that all comments below, prior to Nov 28 2009 are related to another build not to this
that seems working well with RGB and RGBA images

Extract colour-match.exe from the ZIP archive and copy it to your c:\Documents and Settings\[user name]\.gimp-2.6\plug-ins\

(As Windows compilation by Samj was perfect, I kept it in the archive. Mine was several bytes larger...)

Colour Match

Easily map colours from a source colour to a target colour. Very effective for matching skin tones across images or between people.

Relatively quick (but not earth shattering). It doesn't work with grayscale or indexed images. Has preview, works with selections and layers, etc. Very, easy to use, and quite useful for portraits or recolouring graphics.

Relative color remap

This plug-in changes colors in an image based on the HSV difference between two colors. This is particularly useful for applying color themes to existing images.
It avoids burning out high saturation and value at the expense of compression them somewhat when the difference goes towards higher saturation and value.
Current bugs/missing features include:
Undo does not work.
It can't be used on indexed images, even though it would frequently have enough colors.

Tone mapping

It reduces global contrast in images while increasing local contrast and shadow/highlight detail. Use this to make your images "pop."

Translucent border

Creates an outer border of the image with reduced brightness and 2 inner colours.

Split tone

Uses one colour for the highlights and another for the shadows. The following photo was created using the default colours:
