EOS R series camera support


I am using the 202110 snapshot, when I tried it on CR3 files from EOS R5 and R10, both returns a image with purple tint on them, however, it seems working ok for CR3 files from EOS R7. and EOS M series cameras

I downloaded the raw files from the dpreview, using the following link




Could you please specify EOS

Could you please specify EOS R5 files that are not processed right with 202110 snapshot?

Hi Alex,

Hi Alex,

Sorry for the late reply. I have since figured out my mistake. (basically I built the wrong checkout on my computer)

After I corrected my build mistake. the latest checkout works with R5 raw (both compressed and non compressed cr3).

It still have problem with cr3 files that are came from EOS R3 and R10.

I also seem to have another issue with FUJI XT4 raw RAF file. When decoded to HALF and FULL, both works fine. However when I enabled FBDD denoise, the decoded image came out incorrect.



Please make sure EOS R3 and

Please make sure EOS R3 and R10 are listed as supported in the snapshot you use.....
