P: Paste settings from previous Denoises again

[ondrejb47127146]

Hello, I installed LR 14.4 on Mac OS - Develop module - it takes wery wery long time to "Paste Settings from Previous" image when both images are denoised - the time is so long, that it looks like the image is denoised again, even if it was allready denoised.

I apply Denoise as a batch to all high ISO images after grading because it takes a long time and I don't need to sit at the computer, but now it tries to apply LR to each image over and over again when "Paste Settings from Previous" is used, even on images that dont need it. 

Is here a solution/workaround to skip Denoising from "Paste Settings from Previous"  image?

Hi @ondrejb47127146,

Thanks for bringing this up. I understand how frustrating this behavior can be when working with high-ISO images and trying to streamline your workflow.

When you use “Paste Settings from Previous”, Lightroom automatically includes all settings from the previously selected image, including Denoise. If the new image has not yet been through Denoise, Lightroom will trigger the AI Denoise process again, which takes time, especially across multiple files.

Currently, there’s no built-in way to exclude Denoise from “Paste from Previous.” It’s designed to apply all adjustments as-is from the previous image.

To avoid unnecessary reprocessing and speed up your workflow, I recommend this method:
 1. Use “Paste from Previous” only when the previous image has not been denoise
This avoids unintentionally triggering Denoise again.
 2. For already denoised images, use the manual copy & paste workflow:
 • Select the source image.
 • Use Copy Settings and uncheck “Denoise” from the settings.

 • Select one or more target images.
 • Use Paste Settings.

This allows you to batch-apply edits while skipping Denoise on images where it’s already done.

I hope this clarifies and helps you!

Best,

Anshul Saini

Thank you. For now i press "stop" when it starts denoising again, it pastes all settings except second denoising (checkbox is empty) and just by clicking on denoise checkbox it is immediately aplied. without any duplicite calculations.

It would be nice to make "paste from previous" more customisable - something like synchronize settings, but allways just the last selected settings from previous image 🙂

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 Enhance (denoise) process is just not practical for high-volume workflows.

I am back on 14.3.1 after 1 hour of editing.

Apple got this right in Aperture, like 15 years ago. Sadly, Lightroom has always lagged way behind in its UI. Just another example here. 😞

@ondrejb47127146  I am not able to replicate the Paste Settings from Previous Image slowness you are reporting. 

Are you experiencing the issue on Mac or Windows (You've tagged both so I can't tell)

[ondrejb47127146]

It's on MacOS 15.5, MB M4 Pro.

On Denoised images: 

Edit first image, go to second that looks similar, push "Previous" button to instant applying settings - instead of 0-2 seconds (longer with AI masks) it takes over 25s on my 42Mpx RAW files.

On Mac, I am seeing 1-2 seconds for the operation. 

[ondrejb47127146]

I tried it again and installed new version - it was again over 25 seconds for "paste settings" between denoised images. It looks like second denoising.

I change my workflow to edit all images first and after that make the denoise process.

I hope, that it can be done in background like before and it would be without sync time window.

Did you do as the person suggested and uncheck the copy denoise option from the copy settings dialog that comes up when you a copy settings?  Do that first.  Instead of copy from previous, just do a copy.  Then ctrl V/paste settings on every image  you want.  It should do it without the denoise.  

[ondrejb47127146]

Thanks for the copy and paste suggestions, but along with the issues from the forum section "Bring back the ability of Enhance to create a DNG in the background" it's really bad and slow for a batch workflow.

Lightroom 14.3.1 is simply a much better program for wedding, event, sports, family photographers,.... i stopped updates and will wait what happens next.

You said:

> If the new image has not yet been through Denoise, Lightroom will trigger the AI Denoise process again, which takes time, especially across multiple files.

There is still a bug here: if the image has already been Denoised, then pasting Denoise settings CAUSES IT TO CALCULATE DENOISE AGAIN, wastefully.

[michelleg7073996]

I guess I'm still not understanding your issue.  I am copying and pasting all my settings without denoise being copied and the speed of my paste isn't really different.  I am just making sure that the Denoise setting is NOT checked as part of the Copy.  I will have to check that other issue you mention and see if I can tell what you are referring to.  

[michelleg7073996]

I see now that the primary complaint there is that when batch denoising (which isn't as convenient as it used to be with batch "Enhance", the denoise process is slower and nothing else can be done while it happens.  I haven't been batch denoising because I am frustrated that the setting of denoise % won't let me set it before it runs, so I have to manually fix them all after.  So there are definitely kinks to work out.  I'm surprised at some of them given that they already had a good idea about user workflow and removing some key functionality is quite disruptive when you do an upgrade and don't realize you have to change a lot of things to deliver the next paid gallery on the same deadline you had before.

You also can't Auto Sync changes in the Denoise amount slider without recalculating Denoise:

Probably the same underlying cause.
