I have seen a couple of threads on this issue dating back a couple of years, but no conclusive answer as to how to fix it. When I open up a RAW file into Affinity, it is significantly darker than it should be - see attached image showing the same unprocessed RAW straight out of camera being displayed in Windows Explorer and in Affinity. I never used to have this issue, so something in Affinity has changed and caused it. I am using a Canon 7D mkii and 70D and the issue happens with RAW files from both cameras. I am on the latest version of Affinity.
What is going on here, and is there an answer as to how to stop it happening?
