Old Bruce Posted April 22, 2022 Share Posted April 22, 2022 Not to my knowledge, there are many times that I would find it useful.

I have never mastered color management, period, so I cannot help with that. Link to comment Share on other sites More sharing options...

Can you not just rasterize to mask after running detect edges?? R C-R 1 Quote Link to comment Share on other sites More sharing options...

It works for me but since it is destructive I duplicated the layer before using the detect filter in case I still wanted the original available for other work.

NotMyFault Posted April 22, 2022 Share Posted April 22, 2022 Edge detection is simply a Gaussian blur with blend mode subtract or difference, plus a levels adjustment to boost lightness. Add a channels mixer to transform lightness into alpha channel, and save result as mask.
