brush tool on layer mask
Hi, looking for some help. When I have created a layer mask and using the brush to hide/reveal it stops working once I click off. So when using the brush on black or white it starts off doing what it is supposed to but as soon as I move to a different part of the image to brush again it stops working. It starts to do the opposite despite the brush colour not changing and when I do change the brush from white to black or vice versa it then won't do anything at all.
Any advice would be appreciated.
