In GIMP, you can do what you describe with a layer mask. Last I saw,
that's how you did it in Photoshop, too. Here's a short run-down of the
1) Pick the layer you want to change. Duplicate it (this choice is in the
layers, channels and paths dialog, both as a right-click menu on the layer
and one of the buttosn on the bottom).
2) On the layer copy, make the change you want to make.
3) Right click the layer copy and choose "Add Layer Mask". Pick "Full
4) In the layers menu, you'll see a white rectangle next to the copy
layer. Click on it. You're now editing the layer mask.
5) Now you can edit the image with any of the paint tools. Black will
undo whatever change you made on the layer copy. White will show the
changes on the layer copy. Grey will show a combination of the two.
6) When the you're happy about the appearance of the change, right-click
the layer copy and choose 'Merge Down'.
