Yes, I think I did some things the hard way though. I ended up with two images based on my mask, one with all black in overexposed areas, one with all black in underexposed areas. I copied one to a new layer in the other, and selected "addition" as the layer mode. I have to clean up the mask edges (they are blurred already but need more changes) and/or etc. -- Patrick Mansfield _______________________________________________ Gimp-user mailing list Gimp-user@lists.XCF.Berkeley.EDU https://lists.XCF.Berkeley.EDU/mailman/listinfo/gimp-user
