I have some trouble with Raw Therapee detecting the correct lens type on Fedora Linux. It worked pretty well for years and some months ago it stopped working. I was hoping for an update to fix the problem, but it didn’t, so I guess I have to fix something on my own but don’t know where?
Instead of showing the lens type mounted on the camera while taking the photo it shows “unknown” in the information box on the top left side of the image and an empty selection box in lensfun section, the camera model is shown correctly. I have read several threads about similar problems, where there was a problem with the lensfun database and no lenses could be selected. But in my case the problem isn’t that there is no database, it’s all there: I can select whatever lens I want, …manually. But it lacks automatic detection of the lens. I also tried other software like Darktable and DigiKam which detect the lens type correctly, so it just doesn’t work with RawTherapee. Can anyone help finding a solution?
Fedora 31 with latest updates; RawTherapee 5.8-2; Lensfun 0.3.2-22
Edit: Actually read this thread: RawTherapee 5.8 not recognising lens correctly and think my issue is somehow related to what is described there. In my case the lens is also shown correctly in RTs file manager, but only for images which we’re already loaded in RT before this error occurred, all newly added images (taken with the same lenses) show up as unknown. At least installing the latest Windows build like suggested in this thread won’t do the trick running on linux and 5.8 is the latest version.
