Cannot find camera on Linux [solved]

Software darktable
1

Hello,
I am new to darktable and raw editing and I have an issue with my Linux version. I have 3.8.0 (flatpak) on Linux Mint 19.3 and 3.8.0.dmg on my Mac. On my Mac I can find my lens and camera but not on my Linux. It is a Canon EOS 850D with EF-S 24mm f/2.8 STM. Do I have to do something myself or are the versions different?

Any help would be much appreciated.

Can you navigate to the Lensfun folder in Flatpak?

3

The flatpak should ship with relatively recent lensfun profiles. Can you provide a raw file to test?

4

Yes, lensfun/version_1? xml files

5

I am using the same raw file on both computers, .CR3

You may have a couple of Lensfun folders.

For example at usr/share/lensfun/version_1 or /var/lib/lensfun-updates/version_1 or /.local/share/lensfun and perhaps one more folder that Flatpak installed.

Open slr-canon.xml and check if you find your camera model and lens there.

Thanks, it is not there on Linux and I have not yet found it on Mac

For theac version, I think @MStraeten has been cherry picking some newer canon lens profiles. Perhaps he can comment.

Is it possible to copy the xml file from Mac (if I find it) or is it more complicated?

10

Yes, or just cherry-pick the lens and the camera from https://github.com/lensfun/lensfun/blob/master/data/db/slr-canon.xml

11

have a look at /Applications/darktable.app/Contents/Resources/share/lensfun/version_1/ on your mac

Thank you so much, I am lost on Macs.
