darktable Noise Profiles Canon R5 C submission

Hi,

I'm submitting the noise profile files for Canon R5 C generated by darktable-gen-noiseprofile.

It's my first time doing this. I hope that everything is ok.

Just a quick note, I think it would be nice to provide a "standalone program" to be an easier task for people who are not familiar with compiling darktable (a more "user friendly" way).

@TurboGit Is this profile acceptable for 5.2.1 perhaps?

Btw @a42578 we are missing samples for this model, can you please contribute a set to https://raw.pixls.us/ ? TIA

@a42578: I think you are missing transition between the full black (on left) and the start of the lightened area. This makes the curve a bit chaotic on the left for low ISO. Can you redo with a larger transition on the left making sure you have some data in many low-light areas. TIA.

BTW, for 5.2.1 you need to do that in less than 48 hours. Hope you'll fit in the tight dead-line.

Hi,

Sorry. I forgot about that.

I'll redo the noise analysis and send the samples in the next few days.

I want this to be part of the next stable version :)

I tried to redo the noise profiles, but I'm getting the following error:

ERROR: Could not find darktable-noiseprofile tool in /home/a42578/darktable/tools/noise

I got the same error using WSL and also using Fedora.

Any idea how to get around it?

Thanks in advance.

Guess you have to install https://packages.fedoraproject.org/pkgs/darktable/darktable-tools-noise/ but I don't use fedora myself

I managed to make it work.

These are the results: darktable-noiseprofile-20251220.tar.gz

I hope that is everything ok.

I will try to provide the samples to https://raw.pixls.us/ tomorrow.
