This is how I would do it, tho there may be other ways as well. I would duplicate the layer, do my color correction. Add a layer mask and paint the mask such that the areas that I did not want to be corrected showed through, feathering the mask appropriately where necessary. Perhaps kinda tedious if you have a lot of images, but it would work.

Subject: [Gimp-user] Colour correction affecting only particular colours To: gimp-user@lists.XCF.Berkeley.EDU Date: Saturday, August 2, 2008, 6:18 PM Hi all!

I have been struggling to correct skin tones in GIMP without affecting
other colours of the image. The problem is that whatever method I use
(channel mixer, colour mapping, hue/saturation on particular colour
channels), some other hues are also affected (green, blue).

I tried also Select by colour and modify just the selection, however, I
have not succeeded to correctly select just the skin tones.

Pictures are better then words, so here is an example (screenshot of
Picture Window Pro's Colour Correction). Image on the right is being
corrected to get closer to the image on the left, preview of the change
is on the top. Note that other hues (tree branches, clothes) on the
preview are the same as on the source image.

Is there a way how to do this in GIMP?

I would try complex selection -- for example, you can select the skin pretty well using FG-extract selection tool, then deselect green thing and dress using Magic Wand.

Regarding the suggestion to add a layer mask: I've never learned to use masking, but
would the effect be the same if you use the erase tool to show the lower layer through?
Any difference, that learning layer mask would be preferable?
