Well, yet another thread about luminosity masks... you guys might be fed up by this annoying question, but for the life of me I can't figure this out so I decided to ask. I usually do most of my post-production and editing in Capture One Pro, but this software has some limitations and I find Affinity Photo an overall more flexible package with snappier performance and a better interface, so I'm moving my workflow towards Affinity leaving to Capture One the basic tasks of RAW import, lens correction, dynamic range and detail recovery and digital asset management. That said, as I'm trying to move my very simple masking and layer needs into Affinity Photo, I'm stuck with the problem of luminosity masking. In Capture One Pro one can create a new adjustment layer only with those pixels that have a luminosity over or under a certain threshold, with tails that slope down. One could then refine the mask, extend it or brush it away, and of course applying every correction just to that layer. I am struggling to replicate this in Affinity Photo. What I would like to do is to select a luminosity range, create a new masked layer with it and apply adjustments and filters only to it. I went at it with the most naïve attitude possible and I chose "Select" - "Tonal Range" - "Highlights". I then chose "Edit Selection As Layer" to trim it with the eraser brush, but what to do with it now? I suppose I could turn this into a masked layer and apply my corrections, but it still doesn't give me the flexibility of choosing what my highlights, midtones and shadows really are. Where's the cutoff? Can I change it? I then tried to go the other way around with blend ranges, which give unparalleled flexibility in selecting to which tonal range I want my filters to be applied, but it gives me no control over which parts of the images I want this setting to be applied to. Is there something that, well... blends the tonal range selection flexibility of blend ranges and the local control that one can have with brushes and layer masking? I don't know if I explained my situation with sufficient depth: I bought Affinity some time ago but I didn't delve into it properly until the 1.7 version came out, and I'm not a native English speaker. If there is something I missed please let me know, in the meantime thanks in advance for any reply.

Hi, thank you for your suggestion. I suspected that the crap drivers would be a factor in this and this had nothing to do with Affinity. I already own the macOS version and it works very well but I bought the Windows one too as I mainly work with Windows for other reasons and it's impractical to reboot every time. Would adding a eGPU with native Windows 10 drivers help in your opinion?

Hi there, I have happily used Affinity Photo for the last year or so with a 2012 Retina Mac Book Pro (15 in) outfitted with a nVidia GeForce GT 650M GPU (1 GB VRAM) hooked up to an Apple Thunderbolt Display in WQHD resolution (1440p). Affinity was running on Windows 10 Pro, installed in the MacBook Pro with Bootcamp. I have recently stepped up to a new iMac, in particular the I7-7700K/32 GB RAM version with an AMD Radeon Pro 580 GPU (8 GB VRAM) and 5K display where I work with Windows 10 Pro installed with Bootcamp. I expected the thing would fly, but this is sadly not the case. Not being a pro user I don't know how to precisely benchmark or otherwise make objective claims about performance, but I could swear this is not faster than the previous installation of Affinity Photo on the MacBook Pro, and in fact it feels slower since the rest of the applications really do run faster (or maybe it is slower altogether). I know that the screen resolution is much higher, but I believe the VRAM and GPU aren't even in the same universe of those from my old MacBook Pro, so what I'm asking you guys is: are there known conflicts or performance problems with Affinity Photo and the Radeon 580 GPU on Windows 10 Pro? Is there anything I can do or information I could provide you to get a better understanding of the situation? The OS seems to see the GPU and make full use of it when needed, it's just Affinity Photo that is suspiciously slow and laggy when performing ordinary tasks. The files I work with are on the local SSD and synced to OneDrive, but I don't believe this would be a problem because as far as I know they are synced to the cloud after I save the file, and the situation doesn't improve with local-only files either... Thank you very much, have a nice day!
