P: Denoise AI and Pentax K3 MKIII DNG files - not working

An error in my previous post: it's a Pentax KF, not a Pentax XF.

Hello, denoise of a Pentax XF RAW file inefficient with LightRoom Classic.
I changed computer and my new iMac 2023 M3 is less efficient in noise removal with camera Raw AI. The previous one (intel core i5) was very slow (10 mn) but the result was conclusive. Now there's no difference between the original dng (without denoise) and the dng file with sharpening. Any explanation? Could the version of Photoshop for Apple chips be responsible?

To chip in: I have the same problem with my K-3 MK iii. I would love to stay with Lightroom. I liked the denoise with my K-5 and Lightroom is easy to use but if this doesn't get fixed, I might not continue my subscription and switch to DxO PhotoLab. There I can use denoise although it is not as good as what I have seen with Lightroom and my K-5, imo.

Bonjour, j'ai changé d'ordi et mon nouvel iMac 2023 M3 est moins efficace dans la suppression du bruit avec l'IA de camera Raw. Le précédent (intel core i5) était très lent (10 mn) mais le résultat était concluant. À présent il n'y pas de différence entre le dng original (sans denoise) et le fichier dng avec accentuation. Une explication ? La version de Photoshop pour les puces d'Apple serait-elle responsable ?

Ale na początku to odszumianie działało i to nawet fajnie.

Hi Rikk, I own a K3iii (edited) and I ahve the same issue not having the AI denoise reduction working as expected. All the sftware are updated and I can add  the same issue is using .PEF file produced with the camera not only using the .DNG file. I do not know if this is relevant for the guys that are investigating but the question is : as far as you know any statement from Adobe? Any idea of solution if planned? Thanks

wrong bet on tools on your part... DxO can remove that noise ( DeepPrime seems to work better than DeepPrimeXD ) from those Ricoh raw files

>  The problem is the files the camera produces just like with the Pentax K3 where Photo AI and other AI noise reduction software also won't work, so this issue is not unique to Lightroom. 

as noted there is no problem - DxO PL AI/ML NR works on those raw files... just get the tools that actually work, stop complaining

PS: and as a bonus DxO PL comes with optics corrections for your Ricoh's... so DNG you will export to ACR/LR will have both NR and optics corrections already applied

you can always get DxO PhotoLab and use it's AI/ML NR and then export DNG to be used in ACR/LR ... just like with Adobe you of course will be saddled with an extra DNG

I don't have DxO but I do have Topaz PhotoAI and it also cannot remove the noise from the Ricoh files I linked to above (https://www.dpreview.com/sample-galleries/9930153897/ricoh-gr-iii-sample-gallery/6881829042 I used the ISO 1600 image of green flowers). The problem is the files the camera produces just like with the Pentax K3 where Photo AI and other AI noise reduction software also won't work, so this issue is not unique to Lightroom. 

@Jao vdL Thanks. When I wrote my answer, the question wasn't merged with this thread yet, so I wasn't aware of the issue.
