Gauncer Posted July 24, 2017 Share Posted July 24, 2017 (edited) Hi, love Affinity Photo and all the hard work you guys have poured into the software. I have a few questions about Channels and masks. I have watched your video but I still seek information. Frist off forgive me if these are simple issues, I have been working in Photoshop as a professional for over 20 years. There are techniques that are much like muscle memory for me with PS. I struggle in AP to get the result due to my lack of experience with AP. You know old dog new tricks, I want to understand Affinity better. What is the definition/purpose the of the Composite Alpha? I don't see data in the channel, even though the RGB channels show their data. Which leads me to my next question; How do I make an all 3 (RGB) channel selection? I am looking to get all 3 channel data into a single mask (luminosity mask). I would think the composite Alpha would be the place to retrieve that data. In the Channel Studio, there is a "Mask Alpha" that shows the mask I have selected in the Layer Studio. Is there a way to view this mask from the Channel Studio like when you option-click in the Layer Studio? It would be nice to view any alpha with the option-click like Spare Channels. Thank you for your help. Gauncer Edited July 27, 2017 by Gauncer Corrected Terminology Quote Link to comment Share on other sites More sharing options...
Gauncer Posted July 27, 2017 Author Share Posted July 27, 2017 To create a luminosity mask: On the Layers panel, click on the layer's thumbnail with the shift and command(MAC) pressed. From the Layers panel, click Mask Layer Feiying 1 Quote Link to comment Share on other sites More sharing options...
