Lightroom Classic

In some photos, applying the Adaptive Color Profile produces weird, blotchy artifacts in brighter areas, particularly in a sky where there is strong contrast between the bright and dark areas, like a sunrise or sunset. In the attached video, the photo in Develop begins with Adobe Color as the Profile, adjusting the Highlights slider brightens and darkens the sky as expected. Changing the Profile to Adaptive Color produces noticeable, blotchy artifacts in the sky. Adjusting the Highlights slider dramatically changes these blotchy artifacts. Adjusting the Profile Amount slider also changes these artifacts. Enabling HDR mode makes these blotches disappear; adjusting the Highlights moves a prominent bright band up and down in the sky, but the blotches do not appear. I reported this in another photo a year ago, but the problem remains. It means that for some photos, Adaptive Color is quite useless. Has anyone else seen this problem when using the Adaptive Color Profile?  

Hello,Lightroom Classic 15.2.1 (on macOS 26.4 in my case) does not correctly reproduce Nikon Zf in-camera presets (my test is on custom presets).In the Library module, the image matches the in-camera look because Lightroom is showing the embedded RAW preview. But in the Develop module, Lightroom switches to its own rendering and applies Camera Flexible Color, which produces colors that are clearly off compared with the Nikon rendering.So although Lightroom appears to support this feature in principle, the current implementation is not accurate enough to be useful. The user is then left trying to reverse-engineer and manually correct the many settings changed by Camera Flexible Color.As it stands, this feature is effectively broken/useless for Nikon Zf files.Here is a side by side view of what is expected and shown correctly in the Library module (left), and what Lightroom’s Develop renders (right). Thanks in advance for considering this bug report.

I want to just open adobe lightroom but it take me through the creative cloud and then it looks weird and not what it used to be before it got deleted. I want to just open my lightroom but i can’t and it looks the mobile version, i’m on windows 11 PC. I’ve linked an image as to what i have to open to get to lightroom and i don’t want to do that.  

As soon as I import, “fetching previews” is stuck. No previews show.  I have tried updating, restarting the computer and the application, and going to the catalog settings- face detection was not checked/address lookup not checked / culling not checked.   

Lightroom Classic v 15.4 backup attempt results in progress reporter showing “Checking catalog integrity → Copying catalog → Compressing catalog backup,” then reports “Lightroom was unable to back up the catalog named “Lr6 Catalog-v15-4”.  Please check your folder permissions, and make sure that you have available space on your backup drive and main catalog’s drive.”Lightroom has full disc access and backup folder is specifically set to “read & write” for all users.  The backup generator writes a folder named for the backup date into the Lightroom “Backups” folder, but that dated folder remains empty.System specs:  iMac Pro (2017) OS Sequoia 15.7.7, with Mac SSD 2 TB with 790 GB available (far more than the size of a catalog).  Chosing a different folder at parent level produces same result.  Restarting Lightroom produces same result.  Restarting iMac and Lightroom produces same result.  Lightroom restarts and functions (for now), but I am unable to back up my catalog. Thanks for a

I’m a heavy volume shooter, I see daily that Lightroom Classic will fail on HDR merges. No errors, no crashes, LRC will just hang indefinitely on “Merging HDR….”.  You can use the program normally. The only way to fix it is to terminate LRC, re-open then merge the stacks again. I notice it usually hangs on large volumes, say 30-40 stacks at a time. 

it says “Adobe Lightroom Classic” is damaged and can’t be opened. The file was downloaded on an unknown date...

It works fine for a few days and then won’t open.  Task Manager says it is running but I see nothing.  What gives?I should mention my catalog is huge … don’t know if that has anything to do with it.

Even submitting this report has a problems. The category selection is organized weird as well. The Denoise function in Lightroom classic constantly need to be updated and never actually updates. The image never stays denoised. It just keeps asking the user to update and fails without notification of it. It just prompts you to update the denoise function again.

I import CR3 files in daily directories into my catalog. I process the CR3 files then export them converting them to JPG I then import the JPG files to put back into the daily directory they came from and to keyword them. The counters on all the directories are set to zero after this import. I have to exit and restart Lightroom to get the counters reset to their actual number of files in each folder. If I delete the CR3's as no longer necessary the counter goes negative by the number of photos removed.

I’ve already tried every option to improve or fix the slowness in Lightroom’s Develop module. Nothing worked—nothing at all—except downgrading to an earlier version (but that’s absurd; I pay to have the best).

OK. Now I see what happened, so I’ll start over. I’m hoping that someone has an idea for a fix for this.Re: LRC 15.4.1Running painfully slow. A little history: I’ve been a Lightroom user for over 10 years, along the way Lightroom would bog down once in a while, but it always seemed to function good enough, until it became unacceptable. I was due for  a new system so in 2012 I purchased a new XPS8500. Things went well, but the day came where Lightroom slowed to a crawl again. Fast forward to 2018 when I purchase my present system. Specs:Dell XPS8950Win 11 Pro32GB DDR4 2266 Mhz1TB SSD2TB 7200 rpm HDD NVIDEA GeForce GTX 1080 w 8GB GDDR5X Graphics MemoryBDRE DriveWith this system all problems all Lightroom problems vanished and I could multitask with several photo applications along with Lightroom with no problems. Editing became a pleasure once again.Lately everything regarding Lightroom is once again becoming intolerable.I’ve watched several videos on how to speed up LRC, but all to no a

Assisted Culling is now generally available in Lightroom ClassicTL; DR: Assisted Culling has graduated from Early Access to General Availability. It gives you a fast, reviewable first pass on large shoots: it surfaces your strongest frames and sets aside the obvious rejects, so you spend less time comparing near-duplicates. You stay in control: review everything, adjust the thresholds, and override any call. If you tried it back in October 2025, it's substantially more accurate now, especially for wedding, event, group, and portrait work. We'd love for you to give it another look and tell us what you think in this thread.  What it does Open an album or collection, run a cull, and Assisted Culling analyzes your images against the criteria you choose: Subject Sharpness, Eye Sharpness, Eyes Open, exposure, and more. It marks Selects and Rejects, shows you why behind every call, and leaves the final decision to you. How far it's come since Early Access  February 2026: Expanded from individ

Suelo trabajar con un ajuste general a todas las fotos y luego repaso una x una en caso de necesitar algo más.El caso es que a veces uso la herramienta quitar (con IA) o bien, algún preset que contiene alguna máscara.El problema ha empezado cuando le he dado a quitar ruido (y no funcionaba) he actualizado lightroom y ha funcionado. Pero a partir de ahí, cada vez que copio una foto que tiene la herramienta quitar o el preset con máscara, se convierte en una odisea, y me sale en el cuadro de ajustes esto: “El procesamiento de IA está en curso para esta foto.La edición no está disponible temporalmente.”Insisto, hace 4 fotos no me pasaba. Y no sé que hacer. Es muy desesperante.

I’d love to see Adobe introduce AI-powered keywording in Lightroom. With several AI features already added, AI keyword generation feels like the next logical step.I have a relatively small catalog of around 8,000 images, yet keywording is still by far the most time-consuming part of my workflow. I haven’t found another Lightroom task that takes as much time and effort.An AI feature that could automatically suggest accurate keywords would make organising photo libraries much more efficient, allowing photographers to spend less time managing catalogs and more time editing, sharing, and enjoying their images.Is AI keywording something Adobe is actively considering for a future release? I’m sure many Lightroom users would find it a valuable addition.

So I just did the most recent update for Lightroom Classic through CC. When I opened it I noticed the AI Denoise option has been replaced. When I selected the denoise option the following errors happened in the pictures attached. Any ideas to fix this?

LR Classic not opening. Macbook Pro, Tahoe 26.6. I have tried various options, including reinstalling the software and restarting the app, testing catalog integrity etc. Any suggestions?

[This bug report was originally posted on 1/26/2019 in the old feedback forum, but it never got transferred here. See the attached email message.]   In LR 14.3.1 / Windows 11, when LR is in  Window > Screen Mode > Full Screen, floating dialogs always appear hidden in back of the main LR window, and calling the toFront() function has no effect. This prevents my Any Crop and Any Filter plugins from being used in Full Screen mode. This doesn't occur in the other screen modes, nor does it occur on Mac OS 15.5.   This simple plugin demonstrates the bug:https://www.dropbox.com/s/6d1l3llo5dwzzuw/floatingfullscreenbug.lrdevplugin.zip?dl=0 Simply invoke Library > Plug-in Extras > Floating Dialog in the various Screen Modes.

I have a new laptop which I have installed my creative cloud elements. I can open a verson of Lightroom but cannot open Lightroom classic. 

I am having a hard time understanding editing off of a hard drive. I understand smart previews and how it generally works (all on LrC), but I don't understand the importing process. When I got the photos I wanted to import off of the folder on my hard drive, I just clicked import. Am I supposed to be doing something with the "add" button? Also, I'm not understanding collections. Are they a good equivalent to albums? And should I even use them if I have the folder connected to LrC through my hard drive? How do I move the photos to a collection if needed? Will storage be used if collections are used? For reference, I am a portrait photographer editing/culling about 600 photos and delivering galleries of about 100.

Hello: I just updated to the 15.0 release and I think I just discovered a bug. When I click Edit Capture Time via the Metadata tab, whatever time I enter is one hour off from the time that shows up in the EXIF data panel (and how it sorts the photo if "Capture Time" is used to sort the library); therefore to get the EXIF information to show up correctly, I must purposely enter the information one hour behind the time I want it to be (see screenshot where I want 5:31pm to be the edited time, but I must enter 4:31pm to get 5:31pm).  -- Scott, MacBook Pro, Apple M3 Pro chip, macOS Sequoia 15.6.1.

I have been using Lightroom AI Denoise for years. I haven't changed cameras, have not updated my camera, and have not changed RAW settings on my camera. All of a sudden AI Denoise no longer works.
