P: Beta: Output appearance of HDR images varies on different GPU settings

[Pawel Guraj]

Hi.

I've just tested the AVIF HDR output on ACR 15.1 on Apple Silicon Macbook Pro.

It seems broken when GPU acceleration is enabled. The exported images are distorted.

When GPU acceleration is disabled in ACR, the HDR content cannot be displayed, but when exported it's correct - it is correctly display by supported browser (Chrome 108+)

Looks like Windows has the same issue. It seems if you set GPU acceleration to custom and then just uncheck using the GPU for exports, you get proper exporting but the ACR viewport still works (since GPU is still enabled there)

[Pawel Guraj]

Yep, confirmed also on MacOS. When "Custom" acceleration is selected only for viewing not exporting the AVIF HDR files are expored corrextly.

Hi Pawel, can you please explain what you mean by "the exported images are distorted" ?  Can you please post a screenshot or an example of the result?  Thanks.

Also, could you share what settings you used in the Save dialog?

[Pawel Guraj]

This is the photo of correct image:

And this is the distorted one (much more contrast and severe banding on higlight area)

Nothing changed between export - just disabled GPU for import/expoert.

Export settings:

Hello, can you check the color profile of the exported files?

Hi Pawel,

Could you profice a few more details to help us understand the bug?
Please provide a copy of the original file and it's settigns (the one you are exporting).
Can you share with us a log file from Camera Raw? Please see section 4 "Collect detailed logs" on the Camera Raw GPU FAQ: https://helpx.adobe.com/camera-raw/kb/acr-gpu-faq.html

Thank you for your help,
David

On your Widnows PC do you see the distorition when you have the the GPU Pefromance preferences set to "Auto"?
Could you profice a few more details to help us understand the bug on Windows?
Please provide a copy of the original file and it's settigns (the one you are exporting).
Can you share with us a log file from Camera Raw? Please see section 4 "Collect detailed logs" on the Camera Raw GPU FAQ: https://helpx.adobe.com/camera-raw/kb/acr-gpu-faq.html

[Pawel Guraj]

Both files have exactly the same metadata and color profile (Rec. ITU BT2100 PQ)

Hi, 

Under following link:

https://pawel.online/public/for_adobe_bug/

I've place the original file (CR3) and its settings (XMP). There are also two folders with files and logs with and without GPU enabled. 

Br, Pawel

[Pawel Guraj]

Just to clarify. In both cases the GPU is enabled for image processing. 

Option With_GPU -> the GPU is enabled also for file import/export

Option Without_GPU -> the CPU is disabled for file import/export. This option creates correct output AVIF file.

Br, Pawel

[MadManChan2000]

Understood, Pawel. Thanks for the original file + settings, this helps. We'll look into it.

Moved to new thread - setting status to Investigating

[MadManChan2000]

We've confirmed the issue is related to Output Sharpening when GPU is enabled in HDR mode.  We're working on a fix.

In the meantime, the workarounds are (a) disable "Use GPU for image processing" in Preferences/performance, as you already identified, or (b) disable Output Sharpening.

Thanks for your help & patience.

We've just released Camera Raw 15.1.1 which fixes this bug. Please note that this is currently only available via the web links below (not via the main CC installer app):

https://www.adobe.com/go/acr_installer_mac
https://www.adobe.com/go/acr_installer_win

[Pawel Guraj]

Will there be also MAC installer for Apple Silicon?

The one linked seems to be Intel only as it requires Rosetta to install.

Br, Pawel

[MadManChan2000]

Yes, we will eventually also release the installer natively via the normal Creative Cloud app.

In the meantime, please try the one I linked to earlier.  The installer needs Rosetta, but the ACR 15.1.1 plug-in is Universal and therefore contains native Apple silicon code.

[Pawel Guraj]

Cool. I've managed to extract Camera RAW plugin from the pkg without using Rosetta (hate to have it installed).

I can confirm, that export with GPU enabled works well now.

Br, Pawel.

This is fixed in 15.1.1 released yesterday. 

[Rikk Flohr: Photography]

Greetings all,

Updates for Adobe Photography products have been released.  The February 2023  updates contain a fix for this issue.
