Krita is designed for painting, but you don’t have to use it for that…
I’m not trying to make a painting with a drawing tablet, though. I just want to edit the alpha values of an image.

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?

Yea make sure you picked, the from image alpha option when creating the mask.
