Slightly offtopic, I noticed we don't have any wb_presets yet for this camera model. Would you mind submitting those? You could do so, by shooting a single ARW per in-camera white balance preset, and then running this script on the ARWs. Please post back the output of the script.

Will do. Are there any instructions above those at the beginning of the script? I have a cheap grey target somewhere. Should I have that in shot?

Thanks, added to git master: https://github.com/darktable-org/darktable/commit/c2c51b3ed802cdcacc068a002550c8ee070bbf18

I'm afraid I can't process your noiseprofile, so I'll leave the ticket open, until someone who can takes a look.

#7 Updated by Pascal de Bruijn over 3 years ago

And another offtopic remark, I think rawsamples.ch doesn't have an RX100M2 sample yet either, please consider providing them with one.

#8 Updated by Matthew Harrison over 3 years ago

I emailed rawsamples an image. Good idea.

thanks, pushed both the noise profile (more iso stops than what we had) and the basecurve.

The noiseprofile only works up to ISO 3200...

If that is because of any problems with the source data I can take more photos. The camera lists ISO upto 12800.
