I am trying to import Canon R5 CR3 files into GIMP - my understanding is I needed to install the newest Rawtherapee 5.8 (which I did).
When I try the import into GIMP all I get is a giant white square with no picture.
So I tried opening Rawtherapee directly - the preview thumbnails look great - but when I double click on one it also becomes just a white rectangle (see attached Jpeg). The thumbnail turns white as well. Data shows the RGB are all 100%
Am I doing something wrong? Is there a setting I have to set?
I read that I need to make sure CR3 is checked in the preferences/file browser - I looked and CR3 is checked - so that is probably not the issue.
Also - what is the best method - directly pulling into GIMP using the Rawtherapee plugin or using Rawtherapee itself as a stand-alone and exporting it as a TIFF and then importing that into GIMP? I want to retain as much data from the RAW file as I can.
Thanks in advance
