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

How about allowing the amount to be set BEFORE it is applied so we don't keep getting the recalculation EVERY TIME? And retain the last setting? The new feature is implemented poorly as-is, it doesn't work as well as it used to.

Yes, same issue here.
My workflow has become about 5 times slower since the new update. I'm currently considering reverting to an older version of Lightroom to maintain efficiency.

I really hope the Adobe team hears this feedback – the current (denoise) process is just not practical for high-volume workflows

Hi there,

With the new update, we've received a new "Denoise" or "Enhance" workflow. In principle, I welcome the fact that we can now work with a single file. However, I used to frequently process large batches of images. So, I would select "image > enhance." While this took some time, the results were satisfactory.

That’s no longer possible in the same way. I've already come across the tip regarding presets, but I’m encountering a problem. As soon as I apply a preset, Lightroom runs the enhance function for that specific image. Once that's done, I have to manually update the AI settings for each individual image, which also takes time. This means the workflow has not only become more cumbersome but also significantly slower—processing, say, 10 images in a batch now takes considerably longer. My custom preset includes only the adjustments for denoising.

That is commonplace on this forum. It is likely the entire pile will be moved to Camera Raw instead, as the CR Engine underlies all of the Denoise work. Right now, we accumulate posts under LrC because it has 10x the views of CR and 3x the views of LrE. It is a visibility thing to ensure the most numbers of persons see it. 

I understand the two programs received a similar update, but why was a post from the Lightroom CC board merged with a post from the Lightroom Classic board?

Second this. It's inconvenient, it's slower and worst of all: The Denoise breaks under specific circumstances.

I denoised the image on Lightroom Desktop, exported to DNG and moved the file to my LR Mobile device.

The File looks fine and Clean after opening, but as soon as i apply any preset to the image, the denoise is just gone.

I have to say that while I appreciate the work to improve the raw enhancement functions, the end result for batch enhancement leaves a ton to be desired. It’d be nice to have the old enhancement dialog back that then applies the new functionality so we can still select a number of files and leave it to process while we work on other things.

The current suggestion is to do this by syncing the changes, but this is not intuitive and I’d say a bad experience. Not only does it prevent working on other files while this process goes on (in contrast to the old method) but it also does not give any kind of estimate or feedback until after the first file is finished. 

I’d also like to see some prominent mark that it was enhanced so that you are aware at a glance in the grid view. If that already exists I’ve not noticed it. 

Wow, this is very frustrating. I can't believe the previous option was eliminated. I pretty much Denoise all of my images, even those shot at low ISO's since it produces a cleaner image. I am going to have to use the previous version until this is addressed.

Why isn't non-destructive enhance mentioned? Is it withdrawn?

Hello,
After the recent update, the Enhance function (denoise) has become significantly slower. Previously, I could right-click on selected photos and quickly apply Enhance. Now, new ''AI DeNoise panel'  processing around 20 images takes approximately 5 times longer than before.

For example, if I need to denoise around 600 images from a low-light event, the estimated processing time is now 5–7 hours, compared to just 30 minutes before.

Please consider restoring the right-click Enhance functionality or optimizing the current workflow. This change has greatly impacted efficiency.

System specs:

CPU: Apple M2 Max Studio

RAM: 64 GG

OS: MacOs 15.5 (24F74)

App version: Lightroom 8.4 

Thank you for your work and I hope this feature can be improved again.
