You can see in the upper left corner the camera model and in the lower right corner, that the model is not shown / recognised, despite the model is listed in the camconst.json file.
the lens correction permitting to correct the lens aberrations (geometric, vignetting mainly). This function is performed by Lensfun which uses a camara data base for camera crop and lens data base containing the corrections. see Lens/Geometry - RawPedia “lensfun paragraph”
As I see in your screenshot of the lens correction, automatic is checked, so it seems that the camera was recognised by lensfun.
first verification : click on keine. if there is a visible difference it’s ok. click on automatic.
second verification: click on the “down arrow” at the right of “camera”. You should get long list of makers. choose panasonic and then search for your camera.
if your camera is present, select it. But I don’t know why it is not displayed.
if your camera is not present your database is not up to date. You should update your database, but I cannot help you on linux.
Until lensfun database is updated, choose any 4/3 camera as only the crop factor is used.
thank you for looking into my thread. The color management in your RT looks the same than in my RT - that’s good news.
I’m interested in your experience with RT and G9. Could you please do me a favour and develop my pictures and provide me with the PP3 file (in the answer to this post)?
Hallo @Nordschleife,
here is a development and the corresponding pp3. P1044973_RT_M.jpg.out.pp3 (11.8 KB)
With such a motif there would be many different variations - each would have its justification.
Because it is an extreme situation, it is not ideal for learning RT. If you feel like it, we can make further attempts with a more normal picture.

In my post above I was just describing “profiled lens correction”
You can also use" Distortion Correction" in absence of profiled lens correction.
RT uses the embedded jpg that is corrected inside your camera to compute a correction and apply it. If distortion is not too complex (barrel or pincushion), it is satisfying.
Don’t use the both corrections togather.
It’s not that straightforward so for updating the lensfun DB, the normal way is to use the lensfun-update-data script.
In timestamp.txt, you will find a number which increases with updates.
time stamp from my last lensfun update is 1577948414.
I am sorry that I cannot really help you on Linux.
Hello @gaaned92,
I used lensfun-update-data which is also available for Linux:
*carsten@bond:/var/lib/lensfun-updates/version_1> more timestamp.txt * 1578022793
And my camera is not shown in the lens profile section and there is now a visible difference using “non” or “automatically”. Thank you very much for pointing me in the right direction.
