Description

New noise profile for Ricoh GR2 (GR II).
I found the calculated NR much too aggressive, so I modified it, skipping the lower ISOs and moving the remaining ISOs to lower NR values.
presets.json.original is the original aggressive table, presets.json is my modified - please use that.

The change (2 commits) is at my git: https://github.com/teemodk/darktable/commits/master

Please note that "Ricoh GR" and "Ricoh GRII" does NOT share the same EXIF maker:
Ricoh GR = "Ricoh" (this does not work for "GR II")
Ricoh GRII = "RICOH IMAGING COMPANY, LTD."

Thanks
Tomas

I'll only merge the original profiles (a,b values) as all modifications can not be verified. The gui has an strength slider if you want it to be less aggressive.

#2 Updated by Tomas Mogensen 17 days ago

Okay, that's fair. I will just use my local profile then.
I see no point in merging a profile that is too aggressive. That should not be the goal for a "one press" function.

Are you testing the validity of the ab values, but not the effect it has on real images?

Can I eventually get better results (less smearing) with other profiling pictures?
