Lightroom Classic

After updating Lightroom Classic to version 15.6, all Develop module sliders jump to incorrect values when I click and drag them. For example, when I try to increase Exposure to approximately +1.00, the slider immediately jumps to a completely incorrect value, sometimes around -4 or another unexpected position. The same problem occurs with Exposure, Contrast, Highlights, Shadows and other Develop sliders. Directly typing the numerical value into the field works correctly. The problem occurs specifically when dragging the slider with the mouse. I tested a different mouse and the problem remained. I reset Lightroom Classic Preferences and the problem remained. I also tested a completely new Lightroom Classic catalog and the problem still occurs. I also tested with GPU display acceleration disabled, but the problem remained. The problem started after updating to Lightroom Classic 15.6. Before the update, the sliders worked normally. System:Mac with Apple M2 ProLightroom Classic 15.6macOS 

Title: Lightroom Classic 15.6 – Moving selected photo to another folder loses active Grid selectionThis is 100% reproducible in a brand-new catalog containing only 17 photos. Delete works correctly; Move does not. I have deliberately ruled out catalog corruption, sorting, Auto Advance, GPU, folder hierarchy, and multiple selectionEnvironmentLightroom Classic: 15.6 Operating system: Windows Lightroom Classic Library module, Grid view Local folders Problem occurs with both Capture Time and File Name sorting GPU acceleration tested both enabled and disabledProblemWhen I select a photo in Library/Grid view and drag it to another folder using the Folders panel, Lightroom removes the photo from the current Grid but does not make the next photo in sequence active.Instead, the Grid remains displayed with no active photo selected. Navigation keys/commands then behave as though there is no current selection; pressing Right Arrow or Ctrl+Right Arrow jumps to the last photo in the Grid.This is dis

I have been unable to use the AI Masks for about a month. When I click on one of the icons, it blinks like it is making the mask but then does not.

Lightroom was working perfectly this morning.. I come to load in new images and edit some while sitting here.. and as soon as Lightroom opened up - I tried to slide exposure (and other ones to test those...) and the slider immediately jumps one way or another.  I have reset preferences, turned off GPU.. NOTHING is helping.. please help me! 

SummaryLandscape AI masking in Lightroom Classic 15.5/15.5.1 progressively becomes extremely slow during normal use on my system.Immediately after a Windows reboot, a Landscape mask typically completes in approximately 6–7 seconds. After continued Lightroom use, the same operation on comparable images can take 60–90+ seconds.I captured a controlled example in Lightroom Classic 15.5.1:Degraded state before Windows reboot: 86.68 secondsNormal state immediately after Windows reboot: 6.51 secondsThis represents approximately a 13.3× slowdown.Restarting Lightroom does not consistently restore normal performance. Rebooting Windows restores the fast Landscape masking performance.The problem appears specific to, or particularly severe with, Landscape AI masking. Other AI masks such as Sky and Subject do not exhibit the same degree of degradation in my testing.System ConfigurationOperating System: Windows 11CPU: Intel Core i9-14900KRAM: 64 GBGPU: AMD Radeon RX 9070, 16 GB dedicated VRAMAMD driv

Since updating to latest version 15.3 I cannot use my presets or update AI edits.When I try I get a box appear saying I am downloading AI models. This gets to 99% then stops. Then when I try to use presets or update the AI edits I get a red box that says ‘some Ai models failed to download. Please try again later.This has been going on since yesterday. I have tried uninstalling LR and reverting to previous version but problem persists.  Any ideas?  

I have catalog A with keywords and associated keyword tag options (ex. Export Containing Keywords) and export them as a .csv file using Metadata>Export keywords>Include keyword tag options  and then import that same file into catalog B with no keywords currently defined using Metadata>Import, will the keywords and associated keyword tag options get imported correctly to match catalog B?If catalog B has some keywords that don’t match any of the keywords from catalog A - same answer?If catalog B has some keywords that do match any any of the keywords from catalog A  - I belive the keyword tag options will not get updated, correct? Thanks. P.S. I may now regret having multiple catalogs if I have to update each keyword tag option in each one moving forward. 😁 

I’m experiencing a recurring issue in Lightroom Classic where photos temporarily disappear from filtered results and Develop loses the selected photo.My normal workflow is to cull and edit using star ratings and the star-rating filter. For example, I have a photo that is definitely rated 5 stars and edited. When I filter to show my rated/5-star images, Lightroom sometimes says there are no photos matching the filter, even though the image is still in the catalog and still has the 5-star rating.If I close Lightroom Classic and reopen it, the missing photo reappears in the catalog and shows the correct 5-star rating again.I’m also seeing a second issue in the Develop module: I can select a photo normally, but when I click a preset or try to make an adjustment, Lightroom will suddenly switch to “No photo selected.” Restarting Lightroom may temporarily resolve this as well.I have already tested turning the GPU off, but the issue has still occurred.This is especially disruptive because I ph

I want to opem this as a bug but unlike posting a question when I am prompted to click continue to provide more details I get a blank page independent of what browser I am using. Here is my bug discrption. Can anyone help me create this as a bug? Using latest version of Lightroom Classic on Mac running macOS Tahoe Version 26.6.2. The profile browser (in grid mode) displays only a subset of the profiles that are part of the profile. If I expand the width of the browser I can get to a point where all profiles of a profile group are displayed but the view is messed up. Generally, it will show 3 thumbnails in a row with the last one only partially visible. If I chose this third thumbnail the row is then moved all the way to the righty so much that I can no longer see many of the profile names. I did a reset preferences of LR but the problem persists.

When I open Lightroom, I only see gray boxes in the Library, and my thumbnails don't appear. I have the same problem when I try to import photos. I can see the photos in the Develop module, though. I've already adjusted the color profile, but it didn't help.

Since a few weeks, my Lightroom Classic (15.3.1 release on macOS Tahoe 26.5.1) gets stuck or stops responding on simple tasks like:Building standard or 1:1 previews (it gets stuck on ‘Building previews: 3 of …’ but never actually creates one preview) Photo Merge (HDR, Panorama or HDR-Panorama, here the cursor immediately starts spinning and the merge preview does not even pop up) Importing (I can select a source (for example an SD card) but it gets stuck on Checking for duplicates, even when I turn off 'Don't import suspected duplicates’) Exporting (in export I can select all the settings and hit Export but the progress bar remains stuck at zero.I have to use Force Quit to quit Lightroom when it’s not responding.This happens 9 out of 10 times I open up Lightroom, the occasional 1 time everything works fine and I can go on for hours merging huge panoramas or building previews of 100s of photos without problems. But whenever I close and reopen Lightroom the next time it doesn’t work anym

Durch das nicht abschaltbare Raw-Details beim KI-Entrauschen, was normalerweise einen super Job macht, werden Fotos von dunklen Adlern mit leuchtend gelben Schnäbeln inhaltlich verändert, der gelbe Schabel wird mit dem Kopf mal zu einer rosa, mal zu einer grünlichen Masse umgeformt, was leider nicht nur den Schnabel, sondern auch das umgebende Gefieder betrifft, da alles irgendwie verschmolzen wird. Beim manuellen Entrauschen tritt dies nicht auf, allerdings bekommt man die Bilder dann nicht so schön detailliert wie mit dem KI-Entrauschen inkl. Raw-Details. Da ich viele Schreiadler fotografiere, betrifft mich diese Einschränkung leider besonders, schade um die sonst sehr schöne Funktion

This post applies to Lightroom Classic and the Lightroom Ecosystem products. Camera Raw feedback can be found here.   Generative Remove makes it easier to remove unwanted objects and distractions with a simple gesture, even on complex backgrounds. For more accurate results, be sure to include the object's shadow in your selection and/or expand its size.    Detect Objects uses AI to find the objects underneath a brushed area. The masked areas will now appear larger than the Early Access version of this feature. You can also circle objects for quicker selection now.    We have also updated the spot selection experience to make it easier to manage variations, switch the fill type, refine the selection area, or re-generate as needed.    Batch updating is also now supported for Generative Remove spots.    Try out the latest updates and share your feedback with us here.

Desde ayer por la tarde, al querer usar uno de mis preset favoritos, veo que no lo traslada a la fotografía y me sale el siguiente mensaje todo el rato: “No se han podido descargar algunos modelos de IA. Inténtelo más tarde”.Nunca antes me había pasado, cómo puedo solucionarlo?Muchas gracias.

I updated to LrC 15.5 a few hours ago.  Since then LrC has problems with video files.  The first problem I noticed was that when I tried to synchronize a folder that had two new video files.  After a couple of minutes I got the error message “An unknown error occurred while reading the video file. (2)”.  I had just completed those files with DaVinci Resolve so I went back and produced the same files again to check if DR had made an error.  When I tried again with the new files but got the same errors.  I was able to play both videos without any issue using VLC Media Player, so they seem to be OK.  I then shutdown LrC and did a backup including optimizing the catalog, and then restarted it to see if that made any difference, but same error.  Then I started looking at other videos that were already in LrC and found that when browsing them in the Library module, most of them pop up a message “There was an error working with the video”.  They will not play in LrC but work fine with VLC Med

Hi everyone,I'm having an issue with the latest version of Lightroom CC on a MacBook M5 Pro running macOS Tahoe 26.5.1. (I was experiencing the same problem on 26.5 and decided to update hoping it would fix it, but unfortunately it didn't.)Since this morning, it's been impossible to to use Noise Reduction, even though my internet connection is working perfectly. I've already updated both Lightroom CC and macOS, cleared the cache, and optimized the catalog, but I keep getting this error screen whenever I try to use Noise Reduction.Has anyone experienced the same issue or knows how to fix it? Any help would be greatly appreciated. Thanks! 🙏
