P: Bring back the ability of Enhance to run in the background. (LrC)

totally agree. I use Lr, not LrC and switched back to 8.3.1.

The workflow is ridiculously slow and having to hit that dumb yellow button everytime something changes slows you down even more. Besides, why do you need to tweak the Denoise settings? I keep mine at around 80 and it works great. No need to return to change it afterwards.

Also since I use Lr and I only have 5 stars but no colors to sort photos, i just search for DNG files and they show on my grid ready to edit in PS...

Cheers

@Alan Wander: "it makes photos less noise, but in the way when everything look weird and fuc**** unusble. Mostly talking about photos with people, specifically with people in the background of shooted persons. Ai is  not just denoise, but taking back focus and details, which is make people in the background looks weirdos!"

Wierd. There haven't been previous reports about this misbehavior. Please provide:

1. Full-resolution screenshots (not phone pics) from Develop, before and after applying Denoise. Include the open Detail panel in the screenshots.

2. Upload an original raw with the problem to Wetransfer, Dropbox, Google Drive or similar free service and post the sharing link here. We can see if the issue is specific to your computer or occurs on other installations.

3. Do the LR menu command Help > System Info and copy/paste the entire contents here so we can see exactly which versions of hardware and software LR thinks you're running and important LR options that are set.

Has anyone meet the same conflict like me? I have using Denoise since was providet by adobe and using it for events when I shoot in low light or bad conditions. In previous version was Denois slow but absolutely insane, but this new Ai denoise is exactly what provide Remini Ai some times ago.

Yes it makes photos less noise, but in the way when everything look weird and unusble. Mostly talking about photos with people, specifically with people in the background of shooted persons. Ai is  not just denoise, but taking back focus and details, which is make people in the background looks weirdos! 

Dear Adobe, you taking kinda much money to provide someting better !! Do IT!!!

You can zoom the photo to whatever level you want to see the detail of the Denoise effect while varying the Amount slider, unlike the fixed zoom the previous Denoise had. These plus no extra DNG file are significant steps forward in my opinion.

@defaultuz6s618w5u07: "it does not work. According to the version info, I have LR CC 13.4 and the slider for denoising is greyed out. As soon as you tick the box, denoising starts immediately. After that you can move the slider, but it has no effect."

I think you meant 14.4, not 13.4. Here's a screen recording showing Denoise working as intended:

If the slider was broken for everyone, we'd have seen a gazillion posts here by now.  Something is going wrong with your particular LR installation or camera.

Rather than continuing to troubleshoot it in this Idea thread, please start a new thread in Discussions describing what you observe. Do the LR menu command Help > System Info and copy/paste the entire contents into your post so we can see exactly which versions of hardware and software LR thinks you're running and important LR options that are set. Also, upload a sample raw that's not working properly to Wetransfer, Dropbox, Google Drive or similar free service and include the sharing link in the post.

@defaultuz6s618w5u07: "There is no option to manually adjust the level of noise reduction. The fixed value (e.g. 50%) cannot be adjusted"

After you check Denoise and the initial value of 50 is computed, you can quickly change the slider to any value between 1 and 100:

Does that not work for you?

@Kevin21847195h63q: "it seems I am now required to Enhance each photo one-by-one between each photo I edit."

You can apply Denoise to an entire batch of photos at once, rather than doing it one by one -- use Copy/Paste, Sync Settings or Auto Sync to copy the Denoise setting from the first photo to the other photos in the batch. Or you can define a preset, which you can apply to a batch of photos in Library by doing Quick Develop > Saved Preset.

Go back to 14.3.1

@Superpow: "I recently updated Lightroom (version 14.4) and I find myself using noise reduction again. Previously, I would edit my photos beforehand, and then apply noise reduction at the end, let it work, and during this time I could process another album in Lightroom in parallel. Today I have to do 1 by 1 and I can't do another action in parallel. I don't know if I'm clear? Does anyone have this problem? Could you give me some solutions?"

Unfortunately, the new design of Denoise prevents you from running it in background while you do other work in LR. As you can see in this thread, many users are quite unhappy about that.

However, you can apply Denoise to an entire batch of photos at once, rather than doing it one by one -- use Copy/Paste, Sync Settings or Auto Sync to copy the Denoise setting from the first photo to the other photos in the batch. Or you can define a preset, which you can apply to a batch of photos in Library by doing Quick Develop > Saved Preset.
