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

Fixed in LR 13  😃

It doesn't work with my GRIII, but it does work with my GRII.

My test file is from a GRII five years ago

Me using Photoshop shouldn't make a difference, right?

This is weird. No impact at all on my side when running Denoise with the latest firware and updates.

There was a recent firmware update issued by Ricoh. Its possible they fixed the issue for images taken with the new firmware.

It doesn't work for me either (GR III 1.81, LRC 12.5 CameraRaw 15.5).

Luminance noise is still not impacted at all by AI Denoise.

PS 24.7

PSbeta 25.0

Not me.  Running LRC 12.5 CamRaw 15.5
