P: (Technology Preview) Enhance: Denoise, Super Resolution, Raw Details

[Rikk Flohr: Photography]

With Camera Raw's latest update, editing with features like Enhance is now easier and more flexible. When Technology Preview is enabled (configured via Preferences), Super Resolution, Raw Details, and Denoise can be used seamlessly and readjusted like any other non-destructive edit tool without creating a separate DNG file. 

Try out the latest experience and share your feedback with us as we continually improve this workflow. Please also include the following details in your forum post:

Thank you!

Camera Raw 17.0.0.2043 on Windows 11

An observation:

New AI Features and Settings Panel checked.

Open existing DNG file in Camera Raw.

Apply Denoise as standard edit feature (new).

Resulting file causes Photoshop 26.0.0 to crash when selecting Open Object orOpen from Camera Raw.

When noise reduction is performed manually or the older method of applying Denoise and producing a new -Enhanced-NR.dng file , the file opens correctly in Photoshop.

The same applies to Raw Details and Super Resoltion processes.

Further experimentation indicates that this freezing of Photoshop issue only occurs when Camera Raw is hosted by Bridge.

If hosted by Photoshop then Open and Open Object work correctly after Denoise or Super Resolution is applied using the new parametric adjustment.

Works fine here on Intel Mac with Radeon 5500M, Sequoia 15.0.1, using the tech preview (no DNG) with CR2 and CR3 files. Either Photoshop or Bridge-hosted ACR does the job with no crashes. I did have a black screen in ACR on first run but a system reboot fixed it.

After reading your comments I tried the same procedure with some CR2 files. No joy, Photoshop locks up when file is opened from Camera Raw hosted by Bridge. I'm on Windows 11 though.

No problem with Panasonic G9ii RAWs.  Also, Win11.

i did have an initial problem just with PS after upgrading.  Reset preferences.  Don't know if that has any part.

Posted this in the Photoshop forum, but probably better suited to this thread. I've been having an issue with AI Enhance Denoise settings "sticking" when applying via ACR on a DNG opened as a Smart Object in Photoshop. It seems to just discard the AI Enhance Denoise entirely whenever I reopen the smart object in ACR via PS.

--

Expected behavior: Opening a DNG smart object layer in ACR should not reset/turn off AI Denoise (tech preview) in Photoshop once initially applied.

Actual behavior: AI Denoise is applied initially as expected. However, re-opening the Photoshop smart object layer in ACR deactivates/resets AI Denoise.

Reproduce:

1) Open DNG as Smart Object in Photoshop.
2) Double-click on layer to open ACR.
3) Enable AI Denoise. Wait for Enhance to process. Choose any number setting.
4) Click "Done." Photoshop will display the denoised image as expected.
5) Double-click on smart layer to reopen ACR.
6) AI Denoise has been turned off, while other ACR settings remain as previously applied. Reenabling AI Denoise requires full recalculation of Enhance, or reverting to earlier snapshot in ACR.

System:

MacOS Sequoia 15.0.1 on MBP 13” M1 2020, 16GB memory
ACR v17.0
Photoshop v26.0 (same behavior on Beta v26.1)
RAW DNGs captured on an iPhone 12

I often use the denoise functionality, it saved some of my photos and I love it. 

But I often apply it to a lot of photos simultaneously, sometime more than a hundred, and I leave it to calculate in the background.

With the new way it works, it opens a window (like applying smart masks) and I have to wait until it finishes. And that totally destroys my workflow! The window is locked in the foreground, and I can't open any other window of any other app to work on non-camera raw stuff. That's so inefficient, and I hate the way this works! Please, PLEASE change that!!!!

On my Windows 11 system I see some strange CPU usage with Denoise AI in ACR 17, but waited for an update before commenting. Now with ACR Version 7.0.1.2048 I still see strange and excessive CPU usage.

My workflow: I open a virgin Canon CR2 in ACR via Bridge and just tick Denoise. I get the normal "Enhance" progress window, and see some expected CPU in the Windows Task Manager. Takes about 5 seconds, and I see a denoised image preview. All seems good. But then I notice the CPU takes off, climbs to +95%, and stays there for 30 to 40 seconds before dropping back to idle.

I click "Done" in ACR and get the xmp and acr sidecars. Now, when I reopen the image in ACR I see the same strange CPU behavior. Ramps up to +95% for 30 to 40 seconds while I just watch without doing anything. If I open the image via Photoshop instead of Bridge I see the same thing.

If I open the virgin file via Photoshop, click Denoise, and then click Open as fast as possible after the Enhance window closes, I quickly (2 secs) get a proper denoised image in Photoshop, and the CPU quickly drops to idle. That seems to indicate that the 30-40 seconds of high CPU is not really doing anything! I get the same denoised image whether I let the CPU run or not. I got suspicious ACR was phoning home, maybe uploading stuff. So I disconnected my system from the Internet. I still get the high CPU session when air gapped.

Also, when I host ACR in Bridge and open a denoised image into Photoshop, I have a 25 second delay before the image appears. If I host ACR in Photoshop and open, there is no delay. Image opens in about 2 seconds. So, I've been dragging and dropping from Bridge to Photoshop to avoid the long delay.
