P: Denoise on DNG from Ricoh GR-III x is missing Luminance Denoise-

[landov]

Just find out, that DENOISE dont work for RAW files from Ricoh GRIIIx (DNGs)

The workaround with DNG lossless conversion seems to remove too much detail and does not work as expected, unlike how denoise is supposed to perform.

The option for AI noise reduction seems to do nothing to Ricoh GR IV DNG-files. After processing noise is is still visible.  Don't have the same issue with Sony files. Looks like a bug.

Any sugestion what causes it and what could be a solution?

It's best not to hope that Adobe and Ricoh will solve this problem together, but to find suitable replacement products, whether software or cameras. I changed software because I love GR too much.

Same as the GRIII, Ricoh is baking in DNG noise reduction for any image shot over ISO200, and you can't turn the feature off.

Adobe claims Ricoh would have to stop using their baked-in RAW noise reduction for Lightroom's AI NR plugin to work, and Ricoh isn't going to do that (well, they certainly never bothered with the GRIII, so I doubt anything would change with the IV).

Some other advanced NR plugins with work with the GRIV (reportedly... I haven't tested personally), like DxO's PureRaw.

Given's it's been years of Adobe being unable to work around Ricoh's raw NR system, I wouldn't expect it to change any time soon.

I allready tried DxO pure RAW. Not working with the GR IV.
