There is no image attached. You will likely need to post it to Creative Cloud folders or Dropbox, or similar and share a link.

Checking your sample file, the colour noise is being removed. However, the luminance noise is not. 

 

BTW, I also checked Camera Raw and it's no different to LrC. So, issue is not confined to LrC.

Die neue AI Denoise Funktion ist wirklich sehr gut, aber leider funktioniert sie nicht mit Fotos der Ricoh GRIII Kamera. Mit Fotos von meiner Sony A7R III funktioniert alles super gut, aber die Ricoh Bilder werden nicht "entrauscht", auch nicht wenn ich den Schieber auf 100% stelle. Da liegt wahrscheinlich ein Problem mit dem Dateiformat vor. Bitte überprüfen. Danke!

Hier noch zwei Beispiele:

RI002451-DxO_k.jpgRI002451-LR_.jpg

Fotos von meiner A7R III werden mit LR AI Denoise mindestens so gut wie die mit DxO gemachten. MEistens sind die LR Resultate sogar besser.

Das Beispielbild ist mit der Ricoh GRIII mit ISO 12800 gemacht. Das obere, gute Bild wurde mit DxO entrauscht. Das untere ist der misslungene Versuch mit LR AI Denoise.

When using the Ricoh GRIIIx, Denoise AI cleans up the color noise quite well, but leaves very distinct luminance noise.  This is especially true at higher ISO's such as ISO 5000 and 6400.  Not sure why it cleans up much noisier images from older cameras better. And, yes, grain is turned off.

Here's a raw file (I think, barely use dropbox but hopefully this works.) https://www.dropbox.com/t/1zcD3qGzyRWXd1xB

Note that DNG is the native raw format for Pentax/Ricoh.

Dropbox worked, but this appears a different raw than what you showed in your screen capture, so I'm not sure what I'm supposed to see that is objectionable. 

That said, I did open the processed Denoised DNG and did more work in Detail with the Luminance Noise slider, which does work, but I'm not sure that's what your after. 

I see nothing here that would indicate AI not working properly on this camera.

Hi, 

The AI is really not working properly on the Ricoh GRIII cameras. If the RAW from member mrouleau did not reveal it to you then please download and try my raw file from the GRIII. It's obvious that AI Denoise is NOT working properly on these cameras. I already posted examples which prove it above...

 

All the best,

@TheDigitalDog Whatever.  The merged thread shows I'm not the only one seeing this.  If you can't or won't admit that Denoise AI isn't working as expected on the Ricoh GRIIIx, I don't know what to say.

@mrouleau Of course you are absolutely right with your claim!

So far thedigitaldog is the only one I met who claims that everything is fine with AI Denoise treating Ricoh GRIII files.

The following examples clearly show what you, I and many others talk about. These were exported from DNG to JPG from Lightroom:

GRIII, ISO 12800, RAW untreated
https://rebafoto.ch/dpr/RI002451.jpg

GRIII, ISO 12800, treated with Lightroom AI Denoise: very bad result!
https://rebafoto.ch/dpr/RI002451-LR.jpg

GRIII, ISO 12800, treated with DxO PureRaw V3: very good result!
https://rebafoto.ch/dpr/RI002451-DxO.jpg

A7RIII, ISO 51200, treated with Lightroom AI Denoise (no additional manual NR adjustements): very good result!
https://rebafoto.ch/dpr/LR_51200.jpg

This clearly shows that AI Denoise works perfectly with the A7RIII files (and no additional manual adjustements are needed), while it miserably fails with Ricoh GRIII files. A growing number of photographers confirms this.

This concludes this discussion for me, because the case is clear!

I hope this helps.

Cheers,

Agreed.  Denoise works wonders with Canon R5.  With my GRIIIx, the effect is barely noticable.

Hi, I am not sure if AI Noise reduction is working as expected with my Ricoh GR IIIx DNG files. Already in the Preview there is no (really) noticable difference, neither is in the NR DNG that is created. Manual noise reduction has a much more pronounced effect. AI works fine with my Nikon Z7 RAW files though. Is it the Subject/AI, or is it the specific Ricoh DNG? Any ideas?

I can add that I have the same issue with the dng files from the Ricoh GR III.

 

Works great with other cameras I own from Sony and Fujifilm but denoise does not happen on the raw files from the Ricoh.

I can also confirm that I see this same issue with my Ricoh GRIII DNG files. As others have also said Denoise works great on my Sony A7iv raw files
