Lightroom Classic

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?

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

I would like to know which “AI” processes are counted and automatically tagged as such.Since I’m required now to mark images as “Made with AI” and I’m still not sure how that truly applies; I’d like to see how much of the LR features that made it worthwhile I can still use without having to have my clients put AI badges all over the place, or having to provide them with 10 different versions for Social media so the markings are “clearly recognizable” on an iphone 4s as well.Discussing the principle of “faking”, i.e. retouching vs. doing it with/without AI is futile in the face of EU lawmaking, but what processes would I have to circumvent so my work doesn’t get automatically flagged via creator cloud?As much as I love the AI mass masking features, I’ve done well without them for decades and I’d rather live without my work being inadvertently AI tainted. Imo, many automated processes are and have been using some sort of artificial intelligence, video games with “opponents” always did. T

I upload Iphone photos from my phone to the LR Cloud using the LR Phone App. I then go into LrC and let them sync back down to my desktop. No problem so far. Once the photo files are safely on my desktop I unsync from the cloud. I then assign keywords and other metatdata whilst in LrC. My next step is to sync the photos back to the Cloud as smart previews. I do this by dragging the photos to an already synced collection. However, they don't sync. They try for about 3 mins and then they remove themselves from the synced collection. However, they still appear under "All synced Photos" and the blue sync ball continues to spin. However, when I remove these photos from "All synced photos" the green tick immediately appears. To sync these photos I have to restart LrC and then again drag the photos the the synced collection. They then sync properly in seconds. I should add it makes no difference whether I delete smart previews, delete the deleted original files from the deleted folder, save t

Compare view often incorrectly labels a photo as having an embedded preview. To reproduce on LR 15.5 / Mac OS 26.4.1 (see the attached screen recording): 1. Download and open the attached catalog. Observe that Catalog Settings > Standard Preview Size is 2880. 2. Right-click folder "test-pics" and do Synchronize Folder, selecting Show Import Dialog Before Importing. Set the import option File Handling > Build Previews to Embedded & Sidecar. Observe in Grid view that X.ARW is marked with the embedded-preview badge (correct). 3. Do Library > Previews > Build 1:1 Previews, selecting Build All. Observe that neither photo has the embedded-preview badge (correct). 4. With X.ARW selected, go to Compare view. Observe that it says Embedded Preview at the bottom of X.ARW (incorrect). 5. Go to Grid view. 6. Select X.jpg and go to Compare view. Observe that X.jpg is labeled with Embedded Preview (incorrect). 7. Go to Grid view and restart LR. 8. Select X.ARW and go to Compare view.

Olá, estou tentando realizar uma captura vinculada e o Lightroom não está identificando a câmera. Estou utilizando uma Sony 7CM2, um Samsung Book 4, Windows 11… Já testei em um Dell e a câmera vincula corretamente, mas no Samsung não conecta. Alguém enfrentando o mesmo problema?

While working on a project doing a lot of parameters sync, all the pictures suddenly disappeared from the directory.There were 258 pictures in this directory.The directory on the disk is also empty.I have copied back the files from a backup and re-sync the directory in Lightroom.I had to do again the modifications I have done before.

Select a number of photos say about 200 on the film strip. auto sync on Hit auto to adjust the settings automatically. Can be done on library or develop module does not matter to the issueLightroom will adjust the settings automatically and you can go to different photos and the automatic settings would have been applied to all the photos.Now adjust one setting on one photo with auto sync on (eg. bring the vibrance or saturation down back to 0 or a different amount….in this case vibrance to -5)Browse the rest of the photos … The rest of the photos should now have auto adjustments applied + the vibrace slider to where you adjusted it manually. However when I do this other than some photos that are in immediate to left and right of the photo that was active while I did the vibrance adjustment the rest of the photos has the auto adjustments back down to 0 and the only vibrace is at -5. This seems to affect tone and vibrance saturation.. not presence (probably because auto does not affect

Yes, this exact question has been raised many times in the past and those posts have all been closed as “answered” without any resolution.  This is still an issue.I open LrC, import and make edits.  LrC sits idle with computer running for at least an hour.  Try to close LrC and it spends several minutes  "Writing Metadata Changes into XMP" before the app exits.  What is LrC doing while idle after the last edit was made that it now needs to do when I’m trying to shut down the computer?  This is unacceptably poor performance but vaguely understandable as edits were in fact made.  Why are the XMP writes not happening during idle time rather than forced immediately at exit?The same delay occurs without making edits.  Open LrC, make no edits and immediately try to open another catalog.  LrC shows the "Writing Metadata Changes into XMP" message for several minutes before finally restarting with the other catalog.  This is after LrC spent several minutes  "Writing Metadata Changes into XMP" p

I’m running a printing workshop and had to setup a group of mac and windows computers to print on my Epson P900. The printer is using the latest firmware. All the Tahoe computers failed, everything else passed, here is what happened.For each computer, we went to the Epson support page and downloaded the driver for their operating system. None of the computers had connected to the P900 before, so there were no old drivers present. Most of the Mac computers were running Tahoe 26.6.1 or 26.6.2, some were on Sequoia, PC’s were on Win11.We ran the driver installers without issue. For all the Mac’s, we removed the AirPrint printers and added the Epson versions all went well.We opened the Print module in Lightroom and started to setup a print. As soon as I selected Page Setup and chose the Epson P900, something was sent to the printer and it started operating. The printer raises an error on its screen asking for the roll paper adapter to be added. The error can be cleared down and the printer

LrC --> Library --> library Filter: when I set on filter type "raw" and I view date by date, with every change of date the file type filter switches to "all types", so it does not stick on type "raw".  Can I keep it fixed on a certain type?

Oftentimes, I cull my images in Lightroom and rate my selections from 1–5 stars. Once I’m finished, I want to filter the images to show anything rated one star or higher. However, Lightroom frequently defaults the filter back to “equal to”, so clicking one star only displays images rated exactly one star, causing me to miss images rated two stars or higher.I recommend adding an option to lock the star-rating filter setting to “greater than or equal to” so Lightroom remembers the user’s preference instead of continually reverting to “equal to.”Rating is equal to - This auto populates all the time and sometimes I dont notice. 

In the Print Module, I select a paper profile and make a print.  If I move back to another module like Library or Develop to select/change a photo and then return to the Print Module, it has forgotten the paper profile and I must re-select it.  It used to remember the profile in much earlier versions.  I have 15.5 of LrC running on Win 11.  I know 15.4 had this bug and I was hoping that you had fixed it.

I installed the latest update a few days ago.  This is for Lightroom Classic 15. Ever since that time, when I try to read metadata from files, it never completes. I can highlight 5 images at a time and successfully get it to complete, but if over 6 images, it starts and never completes.  

Lightroom is incredibly slow to un-useable. I can use LrC with no problems on my M2 MacBook with 24Gb RAM Memory. I have cleared cache and cleaned my hard rive so plenty of space. all photos held on external 1Tb hard drive as well.

What an awful release. Don't get me wrong, I'm glad to see new developments, but this Lightroom update is an absolute disaster. After culling just 5-10 images, the AI Assist culling tool completely hogs all my RAM, causing my Mac to freeze and throw memory errors. It’s a total nightmare.Culling images via the library module is practically impossible right now - everything just locks up. Even with previews pre-generated and trying to run AI Assist culling, the performance is still abysmal. On top of that, it frequently fails to even generate a Denoise. What is going on, Adobe?! This is absolutely unacceptable!P.S. The RAM management is completely broken and goes beyond any acceptable limits!  

Since recent Lightroom Desktop updates, rapidly culling imported photos has become noticeably slower.Steps to reproduce:1. Open a large series of imported photos in Detail view.2. Enable Caps Lock for automatic advance.3. Press and hold Z to flag photos as Pick, or X to flag them as Reject.4. Keep the key pressed to move continuously through the series.Expected result:Lightroom should advance through the photos quickly and smoothly while the key is held down. Previously, this worked almost like watching a high-FPS burst as a video.Actual result:The flow now repeatedly stutters and stalls. Lightroom pauses between photos before continuing, making this fast culling workflow much slower than before.System:Lightroom Desktop, cloud-based version 9.5macOS 26.6.1MacBook Pro with Apple M3 Max and 128 GB memoryAdditional information:I work with Sony α1 II cameras, producing RAW files of approximately 55 MB each.
