Lightroom Classic

I am scanning a significantly large number of 35mm slides. The slides are stored in boxes and individual slide clips. To identify the location of the original slide, I am entering the box number, clip # and slide # of each slide in the source field (IPTC Status section). Example: Box 4 Clip#32 Slide 20. I would like to be able to search for slides by the source field. The metadata filters do not include a search for source. Can I add this field to the metadata filters? I can enter the information in the Label field which is a filter in the metadata search,  however it adds a white label icon to the photo which can easily be unchecked and then the search is lost. Any suggestions would be appreciated. Thank you,Ruth Goodman 

Hi Adobe Team, I’m posting this as a clear performance regression report for Lightroom Classic v15.x — specifically the Develop module image-to-image switching latency on Mac. REALLY SLOW. Please do not merge this thread into a generic “performance” megathread and then mark it as “Solved” as if nothing happened. Multiple users are reporting the same behaviour, and it deserves a proper investigation and acknowledgement (instead of being dismissed as an “NVIDIA driver” issue — this is Apple Silicon). What’s happening On Lightroom Classic v15.2, switching between photos in Develop is several times slower than in previous versions. This is not a minor “feels slower” issue — it’s a real, repeatable regression that drastically impacts professional workflows. My setup  MacBook Pro (M3 Max) macOS v26.2 Lightroom Classic v15.2 Preferences → Performance → Graphics Processor: ALL acceleration options manually enabled (not Auto)  Proof / Reproduction To remove any subjectivity, I recorded sc

Updated to Mac OS Tahoe 26.3.1 and my Lightroom Classic will no longer detect people in photos. I was running LrC version 14.1.1. I figured that was the issue so I updated to the newest LrC version 15.2.1. Unfortunately it still will not recognize people in the masking feature. It worked fine for me for many years and now nothing, I haven’t changed file type or the way I import photos so I believe it must have to do with my Mac update or Lightroom.  Any help is much appreciated. Apparently this info can be helpful  Lightroom Classic version: 15.2.1 [ 202603161217-0bf813d9 ]License: Creative CloudLanguage setting: enOperating system: Mac OS 26Version: 26.3.1 [25D2128]Application architecture: x64Logical processor count: 16Processor speed: 2.4GHzSqLite Version: 3.36.0Adobe GSDK Version: 1.4.0.212Power Source: Plugged In, 100%Built-in memory: 16,384.0 MBDedicated GPU memory used by Lightroom: 2,429.3MB / 4,080.0MB (59%)Real memory available to Lightroom: 16,384.0 MBReal memory used by Lig

The Windows icons for .lrcat files have been missing for several months. See attachments containing “NOK”.I fixed this for LrC 15.2 by changing the Windows registry entry HKEY_CLASSES_ROOT\AdobeLightroom7.lrcat\DefaultIcon from "C:\Program Files\Adobe\Adobe Lightroom Classic\Lightroom.exe",5 to"C:\Program Files\Adobe\Adobe Lightroom Classic\Lightroom.exe",1See attachments containing “OK”.After installing LrC 15.2.1, the registry entry reverted to '5', which caused the icons to go missing.

This post applies to Camera Raw and Lightroom Classic.   Dust Removal is no longer in Early Access status and can be found in the Remove edit panel for Camera Raw & Lightroom Classic. Dust Removal helps with removing distracting spots on an image that may be caused by dust on a camera's sensor.   Once enabled, your image will be scanned, and any detected dust spots will be automatically removed using Content-Aware Remove. For refinement, you can select one or multiple spots to delete or refresh. Batch removal is also supported; simply select the "Dust" checkbox under "Remove" in the copy settings dialog.Please note that scanned negatives are not in the scope of this feature at this time.    Dust spots on scans tend to be located in the focal plane, with the negative and very sharp, while sensor dust is typically positioned out of the focal plane and therefore not in focus. Scanned negative dust typically appears as white spots on a darker backgro

System: Windows 11 (25H2). Lightroom shows all pictures but doesn’t open them. Importing new images is totally impossible.

J’ai posé une question il y a plusieurs semaines sur le thème [Lightroom Classic Discussions] Re: problèmes récurrents de synchronisation impossible à diagnostiquer. Je n’arrive pas à la retrouver dans la nouvelle communauté, et les liens contenus dans les notifications ne débouchent sur rien. Je veux reprendre la discussion et qu’on trouve enfin une réponse à mon problème !une personne Anshul_Saini m’avait demandé de lui envoyer par message privé un gros fichier de diagnostic. Il m’en a fait un accusé de réception, depuis plus rien. comment retrouver les messages enoyés et reçus ?Comment peut-on avancer ? je suis las de la complexité du fonctionnement de ce forum.

Since updating to LrCC 15 yesterday (Windows 11), I find my workflow much slower. Both the library and develop modules are slower, photos taking a long time (a couple of seconds) to paste settings in the develop module (despite LRCC receiving the input to paste immediately, the effects take a few seconds to apply to the image - this is true across both my Phase One tiff/raw files and my Fujifilm X series raw files).   Anybody else experiencing some slowdowns (as usual with a new LRCC release, unfortunately). 

LR V15.2 hangs in denoise after several images were processed. That suggests a memory leak or a resource starvation, deadlock or any similar issue. LR hangs than, ignores the “cancel” button. When I click on the window [x] the window closes, but LR is still non responsive. When I try to terminate it, it hangs. Using Task Manager “kill process” stops LR finally.  After a restart the previously hanging image processes fine and fast. I am using W11 Pro on a Dell Xeon workstation with 48G RAM and the LR and its cache are on a NVMe drive. When it works, the denoise (and also the AI object removal or marking) are wonderful and they clearly improve the quality of work on our photography. 

Hi everyone, I'm currently trying to migrate my entire Lightroom CC library (about 41,440 images) into a new, empty Lightroom Classic catalog. However, the sync in Lightroom Classic is extremely slow: after more than 20 hours, only about 3,200 images have been downloaded. For comparison:On the same system, I also ran the Lightroom Downloader app, which downloads all images in about 20 hours total – many times faster. The app maintains a stable download rate of 30–100 Mbit/s, with peaks up to 200 Mbit/s. But when I pause the Downloader and activate the LrC sync instead, the download rate drops to below 1 Mbit/s, with only occasional peaks and very long idle times. Sync activity in LrC barely progresses, and it seems to load only 1–2 images at a time, with frequent stalling. Both apps are:Running on the same systemUsing the same networkTalking to the same Adobe serversSo I can safely rule out any system or network bottlenecks. I've already tried:Resetting th

Since the latest versions of Lightroom Classic and MacOS the masking of people always shows “No people found” – even on photos where it was working before. Lightroom Classic version: 15.2 [ 202602111402-ec4112e8 ]License: Creative CloudLanguage setting: en-DEOperating system: Mac OS 26Version: 26.3.0 [25D125]Application architecture: x64Logical processor count: 24Processor speed: 3,3GHzSqLite Version: 3.36.0Adobe GSDK Version: 1.4.0.171Built-in memory: 196.608,0 MBDedicated GPU memory used by Lightroom: 4.743,3MB / 16.368,0MB (28%)Real memory available to Lightroom: 196.608,0 MBReal memory used by Lightroom: 3.040,3 MB (1,5%)Virtual memory used by Lightroom: 55.303,7 MBMemory cache size: 62,7MBInternal Camera Raw version: 18.2 [ 2482 ]Maximum thread count used by Camera Raw: 5Camera Raw SIMD optimization: SSE2,AVX,AVX2Camera Raw virtual memory: 631MB / 98303MB (0%)Camera Raw real memory: 644MB / 196608MB (0%)Cache1: Final1- RAM:519,0MB, VRAM:1.818,0MB, ALP05331.ARWNT- RAM:519,0MB, VRAM

I have an image scanned from a print on bond paper. The image has horizontal lines across it from top to bottom. Is there a way to remove this pattern of lines without going through each one individually?

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. Please also include the following details in your post:  App versi
