P: (Windows - A750 & A770 GPU) New Denoise turning images black and white

[anthonynowack]

Using the new AI Denoise feature seems to darken my images and strip almost all the color out of them. Files are from a Nikon D500 being processed by a Ryzen 5 3600, 32GB RAM, and Intel A750 video card on Windows 11. Tried to create virtual copy of file and reset all other adjustments and it makes no difference. Still dark and almost completely black and white.

[anthonynowack]

Could be. But is that LR not operating properly, or the card not acknowledging the command to turn off? Still a question of is it a LR issue or a Intel driver issue? Is there something specific about this card that Adobe has to code for or is Intel not handling a otherwise universally adhered to command properly? My admittedly rudimentary knowledge of these things leans toward Intel, but they're also an easy scapegoat because of (many) other bugs in their drivers.

When I use the new denoise setting my images come out several stops darker. If I then increase the exposure of the resulting DNG file it looks like the file is lacking some colors (mainly reds). I tried turning off GPU acceleration in preferences but no change. Its doing exactly the same thing for my Nikon and olympus RAW files. Help?

Do you have an Intel A750 GPU?

[Pramodh22261973zuqh]

Yes

[Pramodh22261973zuqh]

looks like my experience is identical to what the others have posted. Is there no fix or does one need to be rolled out via update? 

[Charles Ruscher]

I just posted my issue with Denoise.  Major green cast added to background but not model.  I have an Nvida card.  Looks like we are bata testing which is all good.  Keep the new features comming is what I say.

So it seems to be an issue on the LR side, as you have a different card than others have posted in this thread.

[Rikk Flohr: Photography]

@Charles Ruscher  post of his issue is unrelated to this thread.

It is not could be. It is. LrC uses the GPU for AI Masks and Enhance irrespective of the Use Graphics Processor setting in Preferences. It is 'as designed'. I'm sure the team will resolve this problem.

I have exactly the same issue. My GPU is also Intel Arc but A770 16GB Limited Edition version. I did a clean uninstall of the driver and did not install a new one. Without original drivers, the Denoise option worked fine but took a lot of time. After installing the drivers the output is again black and white and very dark (it darkens as I increase the denoise slider up the scale)

New Denoise not working.  I'm running LC12.3 recent upgrade.  the preview and saved DNG are sort of a B&W version (see attached screen capture.)  I've tried the new denoise on several different file types (CR2 CR3 DNG ARW) all with the same result.

Do you know the support status of Intel Ark for the proprietary GPU recently released by Intel?

If it is not a check target in a rare environment, it may have escaped debugging and been released.

I have the same issue and run a solid new system. 

[Manuel RodríguezA]

Which video card do you have?

[toddc96180025]

I have the same issue going on. Darkened image and devoid of color. This is from a Nikon Z7II and on a brand new Lenovo laptop. All drivers on the laptop are up to date.

[drtonyb]

@anthonynowack There is obvoiusly a problem with LrC/ACR displaying Adobe's own DNG format on systems using the Intel A750 GPU. Here is your Denoised DNG that you shared when I open it in RawTherapee.

Adobe needs to fix this fast.

If you are affected by this issue, please click the up arrow at the top of the post so we can better gauge how many are using this Intel GPU and having the problem.

Thank you.

The graphic card on my (very new) Lenovo Yoga 7i 16" laptop is a Intel Arc A370M 4GB GDDR6 ... and I'm having the same issue.

[Rikk Flohr: Photography]

Thanks for the additional data point

[toddc96180025]

I ran denoise on an image using my old Lenovo laptop and it worked fine. That laptop is a Yoga 710 15ISK using an Intel HD Graphics 520.

So in my case it appears to be an issue when the Intel Arc 370M is in play. I'm running an additional test on my new laptop and will report back.

[toddc96180025]

The result of the second test with the new Lenovo using the Intel Arc 370M is the same: The image is significantly darker and devoid of most color.

[Andrew29579244pc96]

For me the culprit is clearly my discrete GPU (Intel Arc A370M), as I've now established that my integrated GPU (Intel Iris Xe) can perform AI denoise without issue (done by customising graphics setting for Photoshop to 'Power Saving', see screenshot). I'd been having the same problem where AI denoise progressively darkening images and stripping almost all the color out. However, I noticed that occasionally it would work. It then occured to me that ever since I've had the laptop (about 3 months) photoshop would randomly and periodically switch to the integrated GPU (prompting a warning), despite me customising the app as 'High Performance' to use the discrete GPU. Doing so purposefully then solved the issue. In my uneducated opinion there's clearly an issue with Photoshop and Intel Arc GPUs that goes deeper than just the AI noise feature.

Greetings All,

We would like to collect some logs so we can confer with your GPU manufacturer.  Can you please follow the instructions here:

(WINDOWS ONLY) SAVE THE DXDIAG REPORT

The tool dxdiag produces a report that can be helpful to the engineering team while investigating problems.

1. Press the Windows key on your keyboard or click the Windows button in the taskbar.
2. Type 'dxdiag' (this does a search for the program).
3. Press the Enter key.
4. Wait for the DxDiag window to appear.
5. When it's enabled click the Save All Information button.
6. Save the DxDiag.txt file and submit it when reporting problems.
