Bussty Posted October 11, 2019 Share Posted October 11, 2019 I have been looking at ways to effectively mask things like trees and then adjust the background so you can increase contrast, gamma etc in the sky without affecting the foreground. I have tried Remask from Topaz which is pretty good but thought I would try Affinity which is my core image editor. MY METHOD Using the selection brush I make a loose selection of the sky around the trees I then invert the selection I then hit Refine Using the Matt brushes and foreground and background modes I then tidy up the selection so only the tree is selected Using a black background in the Refine tool the trees look pretty good (see attached) In fact a better result than I can achieve using Topaz Remask and faster. MY PROBLEM So now I have the really good selection I need to transfer that into my final image so I... Hit apply Now I have a selection of just the trees To test how good this is and recreate the result of using the black background in the Refine tool I convert the selection to a mask. In my mind this shoud duplicate the effect of the selection including transparency Then I load a pure black pixel layer beneath the masked layer The result is attached As you can see the selection as a mask appears quite a bit different from the refine preview window with lots of bleed coming through. Am I doing something wrong? Am I wrong to expect the mask to replicate the preview window in Refine? It seems if the preview can do it why can't I replicate in the final image? I really enjoyed selecting a tricky subject like this in Affinity and would really like to get this right. What am I doing wrong? or Is there a deficiency in Affinity?

Staff stokerg Posted October 14, 2019 Staff Share Posted October 14, 2019 Hi Bussty, Any chance you could attach the original image or upload it to our Dropbox here and i'll be able to advice further. I'd expect what you see in the Refine Preview would match the Mask Quote Link to comment Share on other sites More sharing options...
Bussty Posted October 15, 2019 Author Share Posted October 15, 2019 Hi Stokerg I have loaded it to dropbox now. Another thing the Refine preview also looks blurry in parts but sharp in the mask but again that doesn't show in the mask.

Staff Chris B Posted October 16, 2019 Staff Share Posted October 16, 2019 Hey Andrew, This looks like a bug to me. I've just had a scan through our reported bugs database and I believe this is similar to something we already have logged. I'm not entirely sure what's going wrong, to be honest, but I'll be passing all this information to the developers.

Maybe you mean this contribution from me (I explain the problem in point 2.). But it was not the first time I reported the problem. Unfortunately nothing has happened so far . Until the problem is solved, I recommend @Bussty (and everyone else) to use the output as layer, because the output as mask or selection is not usable.

Thanks both Chris and Michail hope it's something Affinity can sort. Cheers Bussty Quote Link to comment Share on other sites More sharing options...
