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...)

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.

A demonstration: Lenna's face is mapped to the colour of the feather on her hat. This was done by selecting a colour from her face, then selecting a colour from the feather.  read more »

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.

This plugin evens the tone of an image. It useful in photography for correcting weird light, and can hide skin blemishes.

The layers are not merged to allow opacity adjustments after the filter has been run.

Usually for a photograph, you'll want to use either the sharpen layer, or the "Soft Light" layer.  read more »
