London Posted November 5, 2020 Share Posted November 5, 2020 How do you limited the selection tools to a pre-selected area? Literally 100% of the time, if I have a pixel selection and then use selection tools, it's because I only want to select colors in that area. I do this a lot, but at times am forced to go into photoshop to make a mask there, because I can't figure out how to do it in Affinity Photo.

Alfred Posted November 5, 2020 Share Posted November 5, 2020 You can create pixel masks in Affinity Photo, but a simple way to achieve the result you describe is to duplicate the selected pixels onto their own layer (via Cmd+J or Ctrl+J, depending on whether you’re on Mac or Windows) and then select colours from the new layer.

I dont understand your answer i have same problem tham @London and did exactly the same i need pass through Photoshop. My problem is that: once i have a selection area and later i want to refine this selection for an specific color, to do a mask i really cant. thxs Quote Link to comment Share on other sites More sharing options...

Hi Alfred imagine you have an image like a SKY and you did a selection with different blues (deep blue and clear blue) like a degradee and other colors like withe... you need to select just the deep blue in the selection that you're did first. I don't know how did that I attach you and screenshot. i just want select the blue who are in the black box who is in the selection for made a mask Thx Quote Link to comment Share on other sites More sharing options...
Staff Chris B Posted November 5, 2020 Staff Share Posted November 5, 2020 Select > Colour Range > Select Blues. You can also try Select > Select Sampled Colour if you colour pick the blue sky first—though I find this works better with flat colours as opposed to the dozens of shades of blue in that example.

thatGuy Posted November 5, 2020 Share Posted November 5, 2020 You can use the flood select tool to intersect (select from inside another active selection) or select from all layers (draw another shape to limit your area): 2020-11-05 12-36-50.mp4 Ricardo Sandoval, Alfred and Chris B 3 Quote Link to comment Share on other sites More sharing options...

That's a work around for selections that creates twice as many new layers as you want (or one new layer you don't need). I played with that and tried the flood select tool (which created hard, pixelated edges I couldn't use) and still ended up wanting Photoshop's tools. Sometimes when I'm frustrated with Affinity Photo, I accept it has it's own way of working and my issue is that I'm still thinking like a Photoshop user, not a problem with Affinity's tools. But in this case, I think Photoshop just has better tools. (Or perhaps Photoshop has a significantly superior UI for it's slightly inferior tools.) Affinity's different color modes are brilliant (although why no luminosity mode? so want that), as is the clever formula-based selection tools, but there's no substitute for being able to limit selections to a previous masked area and the add and subtract colors in the color selection palette itself. Erm, unless I'm wrong and just don't know the Affinity Way. Quote Link to comment Share on other sites More sharing options...
Staff Chris B Posted November 5, 2020 Staff Share Posted November 5, 2020 Any chance you can do a recording of how Photoshop does it so I can maybe poke it a bit more? Or at least a tutorial.

London Posted November 5, 2020 Author Share Posted November 5, 2020 (edited) I took a very tricky to mask thing into Photoshop and quickly masked out a selection for a color overlay. I'm not super brilliant at this and this was a quick-n-dirty job, so I didn't take some steps that would clean up some of the trickier elements (or paint them out of the mask). This isn't hair against a similar colored background hard, but still a tricky test. (The numbering on the images shows the order of my steps). The Select and Mask panel (#5) is a separate tool. It's wonderful, but kind of my main complaint is that the basic color select panel in Affinity just isn't as robust and easy-to-use as the one in Photoshop. I got so far with this mask just by tweaking fuzziness and adding and subtracting colors. 1. Initial map 2. Initial selection: 3. Decrese fuzziness to isolate blues 4. Decrease fuzziness even more and use "Add Color" picker to add back greens and browns 5. Finish with Select Color tool, use Select and Mask to refine selection (mainly the contrast tool) 6. After some light painting to refine the mask, use it to create a color overly.

London Posted November 5, 2020 Author Share Posted November 5, 2020 PS, the ability to see the monochrome mini-preview along with the red-overlay on the main image makes it much easier than not having the mini-preview. Quote Link to comment Share on other sites More sharing options...
