Question
Brush tool always subtracts from Mask, whether painted color is Black or White -- what's wrong?
When I use the Brush Tool to add to a Layer Mask by painting black, it subtracts from the masked area instead of adding to it; when I change to brush color to White, that too subtracts from the mask -- so whichever color I use, foreground or background, the result is a subtraction from the mask? What am I doing wrong? How can I add to the mask?
