Lightroom Classic

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. Has anyone had this issue and figured out a solution?Thanks!Lightroom Classic version: 15.6 [ 202609251514-f839cde9 ]License: Creative CloudLanguage setting: en-USOperating system: Mac OS 26Version: 26.6.2 [25G83]Application architecture: arm64Logical processor count: 8Processor speed: NASqLite Version: 3.45.1Adobe GSDK Version: 1.4.0.213Power Source: Plugged In, 80%Built-in memory: 24,576.0 MBDedicated GPU memory used by Lightroom: 5,312.7MB / 18,186.2MB (29%)Real memory available to Lightroom: 24,576.0 MBReal memory used by Lightroom: 1,976.5 MB (8.0%)Virtual memory used by Lightroom: 442,407.6 MBMemory cache size: 670.5MBInternal Camera Raw version: 18.7 [ 2743 ]Maximum thread count used by Camera Raw: 5Camera Raw SIMD optimization: SSE2Camera Raw virtual memory: 1591MB / 12287MB (12%)Camera Raw real memory: 1657MB / 24576MB (6%)Cache1: 

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

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

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.

In the Lightroom Classic Develop module, when using the HSL panel (and similar ones), I suggest using the right mouse button (context menu) to switch between Hue, Saturation, and Luminance modes, rather than constantly moving the mouse back and forth every time you need to change modes (which happens very often). Locked by moderator because reposting in feature requests (while this post was moved there) resulted in a double post.

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

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! 🙏 

Hello,Reflection Removal (Remove > Distraction Removal > Reflections) produces a heavily corrupted image on my Intel iMac. The result is a saturated pink/magenta image with yellow, cyan and black artifacts. The image is unusable at any Amount value.

I experience sync issues in Lightroom Classic for some photos when I add them to a Collection that is synched to the cloud. Only photos that contain Generative AI remove operations are affected. The photos were edited before attempting to add them to a synched collection.I am running Lightroom Classic 15.5.1 on an M4 Pro Mac mini that runs MacOS 26.7.I have found a partial workaround, but it is slow and time consuming. The affected photos appear in the Sync Errors group in the Catalog area at the top of the LH panel. For each of the affected photos, I have to regenerate all of the Removal objects to completely regenerate the data; I have to select each removal object individually to regenerate because there is no bulk operation for a photo. On some photos this may additionally have consequences for masks and I often have to also refresh the masks.Regenerating the AI removal objects does not by itself immediately fix the sync - Lightroom remains stuck. For the sync to complete, I need t

So since 2 days ago, every time I try to apply a preset I get this pop-up saying “Some AI models are downloading. Please try again later.” that stays stuck at 0% and doesn't move.I saw one of the possible fixes may be to log out and back in, but when trying to log out I also get an error, the one in the attached picture.I've tried restarting my computer and router, changing firewall/antivirus settings, running as administrator, reinstalling LrC, and none work.It seems like all of a sudden LrC can’t recognize that I am connected to the internet.Does anyone have any other potential fixes? Thank you. 

Ich habe ein ungewöhnliches Problem in Lightroom Classic.Ich erstelle einen neuen Katalog und importiere einen Ordner mit Bildern. Im Importfenster werden alle Fotos korrekt angezeigt, und ich kann die Vorschaubilder ganz normal sehen.Sobald ich jedoch auf „Importieren“ klicke, verschwinden die Vorschaubilder in der Bibliotheksansicht. An ihrer Stelle werden nur noch graue Kästchen angezeigt.Die Bilder selbst sind jedoch vorhanden:Die Metadaten werden korrekt angezeigt. Im Entwickeln-Modul werden die Fotos normal angezeigt und können problemlos bearbeitet werden. Die Dateien befinden sich weiterhin am richtigen Speicherort und sind auch im Finder sichtbar.Folgende Punkte habe ich bereits überprüft:Es sind keine Filter aktiv. Es gibt keine Dubletten. Der Ordner ist klein und enthält nur wenige Bilder. Das Problem tritt sofort nach dem Import auf.Es scheint, als würden die Bilder korrekt importiert, jedoch werden die Vorschaubilder in der Bibliotheks-Rasteransicht nicht angezeigt.Können

Using an m1 Max, didn't have this issue prior to the latest update to version 9.4  Denoise introduces banding that continues on through to exported files.  Not an issue prior to the update.

I was changing around some things within Lightroom files last week and thought everything was done correctly. But today I saw that there is a wrong connection. In am working on a Mac. In finder, my folder structure is this: 2026 → 2026.08 → other folders. But in Lightroom, there are two 2026.08 folder. One is within the 2026 parent folder, containing other folders. But there is also a separate 2026.08 folder, which contains only one other folder (2026.08.08 - Ameland - sunset walk). In finder, this is all under the same 2026 → 2026.08 folder. There is another problem. When I click on show or hide a parent folder, I am getting this error message:  Database "/Volumes/HD Frouke/Lightroom backup/2026-10-01 1214/Lightroom Catalog/Lightroom Catalog backup 01-10.26 1.lrcat": UNIQUE constraint failed: AgLibraryFolder.rootFolder, AgLibraryFolder.pathFromRootsql: UPDATE AgLibraryFolder SET rootFolder = ?,pathFromRoot = ?

He copiado el catáolgo a otro disco duro junto con la carpeta de imágenes. Cambié el nombre y no me reconoce el catálogo. He abierto desde una copia de seguridad, me abre el catálogo, pero no se visualizan las imágenes antiguas, sólo las que acabo de importar. necesito ayuda urgente por favor. Gracias 

In the custom presets, it is annoying to have to click on the arrow to scroll down. Also it would be more convenient to right click on a preset and be able to have a delete option.

When a video is exported from Lightroom Classic that does not have the size 1920x1080 pixels, it is scaled down. Videos that are in portrait format (1080x1920 pixels) are scaled to 960x540 pixels. A video with 1440x1080 pixels becomes 1280x720 pixels when exported. Do not scale videos during export.  

Hi everyone,I'm having a persistent issue in Lightroom where all files appear blank/grayed out during import, and clicking "Import" does nothing. The issue: Happens with all file types and folders from all different cameras/drives. What I've tried: Completely uninstalled/reinstalled Lightroom, tested multiple different versions, and tried every troubleshooting fix found online. Nothing has worked so far. Does anyone know how to fix this? Thanks! 

Select Subject in Lightroom Classic has suddenly become significantly slower on my PC. It previously worked much faster on the same hardware (2-3 sek).System: NVIDIA GeForce RTX 5070 12 GB, 32 GB RAM, Windows 11.Tests with the same images:Lightroom Classic 15.5: 13–14 sec Lightroom Classic 14.5.1, completely new catalog: 7–11 sec Lightroom 15.5 with GPU disabled: 14–18 secLightroom recognizes the RTX 5070 and reports full graphics acceleration. However, GPU utilization appears very low during Select Subject.Since the problem also occurs with a new catalog and different Lightroom versions, it does not appear to be catalog-specific.Around two weeks ago, Select Subject was considerably faster on this same computer.Could you please advise whether this is a known issue or help identify what may have changed?

I have more external USB drives than USB sockets on my PC.  This requires me to occasionally swap the main USB drive holding my RAW files to another socket or to reconnect after it has been removed. Lightroom often doesn’t recognize that it is the same drive and allocates a new drive letter, consequently it says files not found and I have to re-sync all of the files which loses the history of which files have been edited.  Could you have Lightroom recognize the drive and allocate it the original drive letter and retain it even after removal.

MacBook Pro M3 Pro and MacBook Pro M5 Max MacOS 27.0.1 aka Golden Gate I have a catalog i made for test purposes this June containing 109 Nikon Z8 non compressed photos.When i tick the Denoise box runtime is 3 seconds, great!However, if i make a new catalog with the same 109 photos then runtime is 11 seconds :-(I did many test and catalogs and same happen, denoise time is 11 sec on the M5 Max and 17 sec on the M3 Pro what is not surprising.It seems to me that the catalog who does denoise in 3 seconds have the photos only in a collection as but no photos are shown on disk. See the attached screenshotNow i am a bit confused about why i can edit photos if the original is not on the disk but in a collection ?Exporting the edited photo i get a warning window saying, but export works perfectly fineSo from what i understand in this case i work with smart previews instead of the original file.What i am wondering why is the Denoise time for Smart Preview so much faster; 3 seconds instead of 11

Installed this and my tethered camera setup no longer works.  It appears to work as before, but no images are transferred.  Canon R1, Windows 11.  Anyone else having tethering issues?
