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

Mise à jour de Camera Raw ce matin, et malheureusement la réduction du bruit par l’IA est toujours inefficace pour les fichiers raw de Pentax. Les ingénieurs d’Adobe semblent se désinteresser du problème. Quelqu’un a-t-il des informations ?

Camera Raw updated this morning, and unfortunately AI noise reduction is still ineffective for Pentax raw files. Adobe engineers seem to be losing interest in the problem. Does anyone have any information?

Ale tak czy inaczej powinni to zmienić. Powinno to działać. 

Prędzej to odszumiał pliki pef z Pentax k-3 Mark III 

A przedtem działał na plikach z Pentax k-3 Mark III 

@andrzejv90126968AI Denoise works on PEFs from older cameras like K-5 and K-3(1). It doesn't work (and has never worked) on PEFs from  cameras which apply noise-reduction to the RAW-files, like KP, K-1 II and K-3 III.

Na początku w wersji 12.3 dzialało super na plikach PEF nawet na slabej karcie graficznej. Zdjecia mozno zaszumione były dobrze odszumione. A teraz ostatnio to nie działa na plikach PEF i nawet DNG w Pentax-a

Adobe has acknowledged the bug. See pinned reply by @Rikk Flohr: Inactive at the top. No fix yet so this must be a non trivial bug. It has nothing to do with GPU or other parts of the system and that was well established here by us all. It is just a bug where this doesn't work with pentax K3 and probably a few others. The support people on the phone are usually not at all aware of these so no surprise that they keep steering people in the wrong direction.

I have RAW files from several cameras here. Lightroom AI Denoise works perfectly fine on all of them - except for files from the Pentax KP and Pentax K-3 III. The results are consistently bad - either no visible noise reduction at all or blotches with slightly reduced noise. Both cameras produce RAW-Files with baked in noise-reduction (which can't be turned off). That may be the specific characteristic which Adobe has to investigate / train their AI for.

@danilot27785307 Yes, I have an 8GB graphics card and I strongly doubt that VRAM is the issue here.

I do not own thankfully any dSLRs, so I downloaded a sample from dpreview... I have RTX4070 dGPU (12gb memory)... in my case Adobe's enhanced NR does "work" ( as you can see the difference between applied / not applied ) - but not something that I 'd call a great NR ... may be because Pentax already applies  NR to all raw files from K-III ( that you can't switch off ) and Adobe was not able to do better than this quite poor NR  ? 

Hi all, after all What I said I received a call yesterday from Adobe, some minutes I post the replies. Strange ! They told me the issue stand in my poor 4GB graphic card (again), then they suggest me the issue was with a single file only (again). I rejected all this assumpions because I said and I prove them :

1) with my system I can denoise a NEF file easily

2) I cannot denoise any K3iii DNG or PEF file, not just one

My english is not so good but I think I understood he 'd have to talk with the expert to fix the issue in the next Ligthroom updates release .

Then I received an email that says "issue closed" .

For sure the issue is not close

If there is any LR user that has a Pentax K3III or a ricoh with a 8GB graphic card , could you please post your feedback here? Is the AI NR working on your machine?

I will open another case, at least until :.

1) they will fix it

2) they will admit K3iii is not 100% fully compatible with Adobe LR ( at the very end I cannot ask something they are not able to fix)
