White is supposed to add to the mask. But it keeps removing the mask. In other words, using a white brush deletes that part of the mask and reveals the image underneath when it should be covering it up. v. 2.8.16 > > Any ideas? > TIA, > Rick When using QuickMask, right-click on it and you can configure whether it should highlight the masked (selected) or unmasked areas; set it to whichever method works best for you. Nonetheless, the underlying operation of QuickMask is the same: white = selected and black = not. -- Stratadrake strata_ran...@hotmail.com Numbers may not lie, but neither do they tell the whole truth. ___ gimp-user-list mailing list List address:gimp-user-list@gnome.org List membership: https://mail.gnome.org/mailman/listinfo/gimp-user-list List archives: https://mail.gnome.org/archives/gimp-user-list

It looks like you got it wrong. Think about black and white as 0 and 1 respectively. In a selection, 0 means "it's not selected" and 1 means "it's selected". This is also consistent with layer masks, where black makes pixels transparent while white makes them opaque. Since you can produce layer masks from selections, it makes sense that those values are consistent. And why are black and white used that way in layer masks? Because masks work like alpha channels. So, when you paint white, you're painting the pixels you want to be selected, the ones to be visible. It makes sense that those are not "masked out" by your quick mask.
