creature Posted November 13, 2021 Posted November 13, 2021 Hello, I'm running Affinity Photo 1.10.4 on macOS 10.14.6, and trying to develop a RAW file from a Fuji X-T4. (This isn't supported by Mojave's RAW engine, so this should use Serif's engine instead.) I only had one light available for this family portrait, so I've used a couple of gradient layers to brighten up the top and bottom of the image (exposure about +0.5). Basically, the exposure changes when I click "develop". Here's a screenshot just before I click "develop": And here's the image as it "lands" in the Photo persona - now overexposed: There's also an odd square in the top right. I recorded a screencast of this process too: https://youtu.be/5qE6YNDcQ1A Quote
Staff stokerg Posted November 14, 2021 Staff Posted November 14, 2021 Hi @creature, Can you you try going into Preferences and on the Performance section there is an option for Enable Mental Compute. If thats ticked, untick it, close Preferences and restart Affinity and then see if you can replicate the issue. creature 1 Quote
creature Posted November 15, 2021 Author Posted November 15, 2021 Thanks for that suggestion! "Enable Metal compute acceleration" was checked; after unchecking & restarting Affinity, I could import this RAW without those problems (neither increased exposure nor odd squares). My Mac is a 2018 MacBook Pro; the graphics chips are a Radeon Pro 560X 4GB & Intel UHD Graphics 630 1536MB. I'm guessing this is a known issue, given your suggestion? Should I leave hardware acceleration off until a future update, or is it better to turn it back on and disable it only when I have issues importing RAWs? Quote
