In the process, I opened a few GX9's RAW (RW2) files with Affinity Photo, my Adobe DNG Converter (10.2) is not able to convert the "new" file yet.
My usual workflow when I review a camera is to shoot BOTH JPEG and RAW files.
The RAW are converted to DNG and open in Adobe Camera Raw, so are the JPEG and both are adjusted in ACR where necessary.
This time round I notice something strange between the JPEG and RAW that I cannot explain and I think it is worth some investigating!
