Painting in white on an inverted mask does not make content appear complete

[RainerH]

Hello,

in Photo, when I paint in white on an inverted (completely black) mask using the Brush tool, the image does not fully appear in the painted area. The background shines through. As I brush over the same area multiple times, the opacity gets higher and higher. I'm sure I just picked a wrong setting, but I can't figure out which one. Maybe the screenshot will make it clear what I did wrong. Thanks for the help in advance.
Best regards
Rainer

Hi there!

Make sure the Wet Edges is de-selected

Hello @RainerH,

in which blend mode is the brush set?

Set the blend mode to normal and it should work as expected.

Cheers

Thank you for your help. The solution was "wet edges" ("nasse Kante")
