In gimp just right click the layer, choose add layer mask, then pick from layer’s alpha channel. You now have a mask layer you can paint on.

Is there a way to do this, working off of the existing values? For example, copy an image’s alpha values onto the mask so you can then adjust brightness/contrast?
