    I upgraded to Debian Bookworm which made rawtherapee version 5.9. It has been a few years since I have used rawtherapee and I have forgotten much.

    I downloaded a DCP file for my Canon EOS R5. I copied the DCP file and /usr/share/rawtherapee/camconst.json to the ~/.config/rawtherapee directory. I edited the json file to change the white level and clipping. The reason for changing the clipping was to account for IBIS moving the sensor. I chose a value that is often in the exif for the white level.

    diff /usr/share/rawtherapee/camconst.json ~/.config/RawTherapee/camconst.json 
    1219c1219
    <         "raw_crop" : [ 128, 96, 8224, 5490 ],
    ---
    >         "raw_crop" : [ 64, 64, 8352, 5586 ],
    1221c1221
    <         "ranges" : { "white" : 16382 }
    ---
    >         "ranges" : { "white" : 14008 }
    

    Some image files seem to work very well and others not at all. I suspect I have done something wrong.

    Examples were not keepers, but for learning how to use rawtherapee.

    Building from source metadata-exiv2 branch fixed the problem.
