I am embarassed to ask this question but I have been searching for an hour and just can't find an answer. Details: PS 2021, MacOS Two Layers Reveal All Layer Mask on Top Layer Brush set to: Hardness 100, Opacity 100, Flow 100
I start painting black and I get a 50% grey.
If I change the Layer Mask to Hide All and paint white again I get a 50% grey and can't paint pure white.
It has to be something incredibly stupid that I am missing but I can't figure it out.
