Lightroom Classic

System:Lightroom Classic 15.3.1 running on Mac mini M4 Pro 48GB 650GB spare storage.Catalogue is on the internal Mac mini SSD. Problems:This problem occurs frequently:Open up LRC, Edit three or four images in Develop module. Proceed to next image, but the image in the Develop module doesn’t change, or there is a grey panel. Shut down LRC - Writing Metadata changes into XMP…sticks at 29% and makes no further progress. So I have to force close LRC. I have tried disabling GPU etc. Any suggestions please? Thanks Richard

Why is Adobe Light Room so slow? Simply scrolling through the film strip can take seconds between images. Newly added images can take up to 30 seconds. Stitching is super slow to create panoramas compared to other programs like PTGUI. Simply selecting the crop tool causes the LR screen to go grey and then refresh. Everything I do in LR is slow and I’m constantly waiting on it.   

when I try to use the replacement tool with the Generative AI option I get the message: “Generative Remove FailedWe've encountered an issue and can't complete your request at this time. Please try again later” this keeps happening no matter how much later I leave it

RAW file exported as jpeg (5 meg) in Lightroom Classic V15:3:1 with content credentials applied I see no CR pin on the image as suggested in Adobe help videos.

Lightroom Classic 15.3 intermittently becomes completely unresponsive (permanent hang, requires Force Quit) when opening RAW images in the Develop module or when generating previews during import. A macOS `spindump` captured during a live hang shows the cause is a **self-deadlock inside the Camera Raw engine** bundled with Lightroom Classic 15.3.The operating system's own deadlock detector flagged it. The spindump header reads:- `Deadlocked: 1 thread - Thread 0x11612a "Queue Processor - NegativeQueue_1"`- `Blocked by Deadlock: 3 threads - "Queue Processor - OpenNegativesForDevelop_1, _2, _3"`The deadlock graph points the thread **at itself**:`Deadlock: ... thread 0x11612a "NegativeQueue_1" -> thread 0x11612a "NegativeQueue_1"`The deadlocked thread's call stack runs through AgKernel (Lua) into CameraRaw, ending at:`... (CameraRaw) -> std::mutex::lock() -> _pthread_mutex_firstfit_lock_slow -> __psynch_mutexwait`with the kernel annotation: `(blocked by turnstile waiting for th

I run LrC 15.3 om a Mac Powerbook. I purchased a new WD 24TB hard drive when my old 12TB filed up, and moved my photo files to it. I also just returned from a trip where I imported several thousand pictures as well. When all migrating and importing was done, the catalog seemed happy. All pictures were recognized. Since then, pretty much every day for the last four days when I open a collection a number of pictures have the dreaded exclamation point indicating that the picture can’t be found. For the past three of those four days I’ve reimported those pictures from a 2TB travel drive and reedit the pictures. Yesterday evenoing all was well. This morning I have the same problem. I haven’t moved to 15.4 because I didn’t want to compound my problems with a new catalog and new version. Any thoughts or suggestions would be greatly appreciated. Thanks.Marty

I've been uisng LR for a while to apply my photo presets to video clips, as a simple means of getting my photo preset applied to clips for consistency. So applying the preset on import, then exporting the clip to edit in other software.Now with LR 17.4, when I go to export, the export dialog progress bar apepas in the top left, but there is no progress, nothing happens. It just sticks on 'Export XX files', and wil stay like that for hours or even days with no progress at all. There are no error messages, and when I work through the export dialog box there is no indication that it isn't going to export.Any ideas? Thanks in advance. 

I get this error message every time i try to apply an adaptive preset to an image.All the portrait ones do no work, same for subject and blur backgroundOnce you try to apply the preset, the error message pops up after 2 seconds. so it is not running and running to find something and then times out. Error Message pops up nearly immediately Categories not affected are the sky presets and the landscape presets.LRC Version : 15.3 Any idea how to solve this? Thanks Jay

I haven’t been able to sync my data to the adobe cloud. The sync keeps getting stuck and I’m not sure what’s hanging it up.

LrC won’t open as it is saying that my Master Catalog is corrupted.  But it doesn’t tell me what to do about it.  It gives no other options.  I need to be able to open LrC

I now have 15.3.1. Last update I remember I was prompted to answer a question about my catalogs. Maybe I did not answer the question correctly.

Hello, the “Adjust overall exposure” feature for multiple selected photos in the Develop-Module is suddenly grayed out / unavailable when I select “Right-click > Develop settings > Adjust overall exposure”.When I set “Auto-Synchronization” to ON, the grayed-out status disappears and the function becomes available again. I only have this problem in the Develop-Module - and only when using “Right-click > Develop settings > Adjust overall exposure".All other options work (without “Auto-Synchronization”):- In the Develop-Module, “Settings > Adjust overall exposure” works.- In the Library-Module, “Photo > Development Settings > Adjust overall exposure” works.- “Ctrl + Alt + Shift + M” in the Develop-Module works.- “Ctrl + Alt + Shift + M” in the Library-Module works. As I mentioned, only in the Develop-Module the “Adjust overall exposure” function suddenly is grayed out / unavailable under “Right-click > Develop Settings” and only works after enabling Auto Sync. I di

 I am having trouble accessing about five years worth of digital catalog photographs through Adobe Lightroom. My problem started I think when either my macOS system software updated or adobe Lightroom updated its software.  Originally, I couldn’t find these photos anywhere on my hard drive so I had to retrieve them through Time Machine on my Mac. Once I located these catalogues I copied them over from Time Machine. I am unable to open them through Lightroom. I keep getting this warning.  Can you help me with the ability to open my Lightroom photo catalogs again?    And what does it mean when the LrC warning says “does not allow files to be created within it.”?  

I am creating a book in Lightroom but the format is only US (20*25 cm).Is there a way to put it on A4 (21*29.7 cm) ?

When I press the denoise box, it doesn't do anything. It ticks for a split second and then doesn't do anything. How can I fix this? 

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

Hi - I have run into an issue this morning where Lightroom is reapplying a preset to images I have edited in Photoshop and have saved back into Lightroom. Usually I apply a preset to my images automatically when I import them and have no issue for any that I have to edit additionally in Photoshop, but today Lightroom has decided to add this preset on top of images that already have it applied, which is resulting in slightly off-looking images. Has anyone else run into this problem? I’ve spoken to my colleague with much more experience than me and he says he’s never seen this happen before. Thanks for any advice you can give. If it helps I’m using a Mac and running Lightroom Classic 15.3.1

I have tried to change setting in the LR Preferences Tabs, Changed  GPU for visualization only. Disactivated facial recognition, AMD GPU drivers are all updated, Changed file paging settings. After all these changes noted only slight improvement and erratic unstable behavior  This is my system configuration :     AMD Ryzen 7 260 w/ Radeon 780M Graphics         (3.80 GHz)     32,0 GB (31,3 GB utilizzabile)     Catalog on Internal SSD 215 GB available     Camera Raw Cache 100 gb     Windows 11 Pro 25H2 Build:26200.8655

I keep having trouble when starting Lightroom Classic.  It hangs withg the spinning circle and I have to Force Quit.  I can usually get it going, eventually, by going through the routine of Shift+Option start to reset preferences.  If that does not work I do an Option restart and check the box to check catalogue integrity (which can take some time).  If these fail then I reboot the Mac, and sometimes have to repeat the above before LR will open properly.This is on a New MacBook Pro with M5 chip, 32GB Memory and 4TB SSD running Tahoe 26.4.1.  It was happening before upgrading to this version of MacOS.  LR is on version 15.3.1 (LR Classic)Does anyone know how to stop this happening almost all the time? Hopefully, Richard

Hello, my raw files are getting color distorted in Lightroom.I tested different card reader, different apps and different PCs.This issue is showing on exactly one PC, not any other in the household.I will try updating graphics drivers tomorrow, Lightroom was up-to-date in the time of the incident.Image shows distorted even when exported.Attaching examples of affected images.Thank you for your tips. 

I moved my LR Catalogue from desktop to hard drive then copied it to laptop.  The collections did not load.  How can I get them back?

I do not find my two external hard drives any more in the folder besides the internal hard drive in Lightroom 3.6 although I did not change anything. Or is it correct that the external hard drives appear here in the subfolder in the internal hard drive named Macintosh HD?
