DMC-G9m2 Support

Hello - I’m a new user to this forum, a G9M2 owner, and linux (Ubuntu) user. I have enabled the work around above and have also downloaded and used the noise profiles. Have only tested about 20 files for noise removed so far but all tests worked and I love the results. I can confirm the magenta noise preview images bug as well. In my case, the images that exhibited the issue came from a G10.

Is there a way to get the lens corrections to work?

How did you install Darktable? I am using the Appimage for v4.8.1, and the lens corrections work. I believe the Appimage ships with the lensfun DB of correction info, whereas with the apt packages use a version of lensfun from the repos, that may be more out of date.

If running from a native (deb) package, try running the following command at a terminal:
lensfun‑update-data
You may have to restart darktable after that.

I run Fedora x86-64 and am up to date, with these versions of various packages

$ rpm -qa | grep -i raw
LibRaw-0.21.4-1.fc42.x86_64
libraw1394-2.1.2-23.fc42.x86_64
perl-Compress-Raw-Zlib-2.213-2.fc42.x86_64
perl-Compress-Raw-Bzip2-2.213-2.fc42.x86_64
kf5-libkdcraw-23.08.5-3.fc42.x86_64
rawtherapee-5.12-1.fc42.x86_64

if I try and open an rw2 file from my recently acquired G9ii then all I get is a pixelated mess.

I’m not using Darktable, just trying to load the raw files into GIMP.

Raws from my previous camera, G9 mark1 are fine.

thanks for any ideas.

Welcome!

The G9m2 is not supported by that version of LibRaw, it needs a more recent “snapshot”.

You’ll have to use darktable for import, and connect it to GIMP. RawTherapee might work as well. (Or use different builds of LibRaw etc.)

thanks for that kmilos. In theory I should be able to build a newer libraw given the comments in this thread.

While you can certainly build newer LibRaw itself, linking other apps to use it is a different matter as the API and ABI (“soversion”) level has changed. Directing GIMP to use dt (or RT - you might have to disable LibRaw in its preferences though) as raw loaders is a much easier workaround…
