GIMP Plugin Registry

This script does LAB sharpening using the unsharp mask in the luminance (L) layer. It decomposes the image into LAB layers, sharpens the luminance layer (using the supplied settings), and then recomposes the image. The interface is the same as the unsharp mask (radius, amount, threshold), but the filter is only applied to the luminance layer.

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 »
