Can't use lightroom classic as can't access catalog.  I am getting the following error message:On windows 10.  All software including lightroom classic appears current and updated.  Tech note does not appear to relate to my issue and did not resolve the problem

Today after long editing session I noticed that my PC slowed down noticable. I looked up into task manager and saw that Lightroom uses 13GB of RAM + 12GB usage from Photoshop. I thought it isn't that much, because I have 64GB of RAM, but it's usage was at 98%. After I closed Photoshop RAM usage dropped by 15GB and after closing Lightroom usage dropped by 33GB! That's huge amount of RAM usage and it was 20GB more than task manager was showing next to Lightroom process. Is this a bug?LR Classic 13.1Windows 11 Proi7-13700KRTX 408064GB RAM

Lighroom Classic randomly stops exporting. I'll be exporting single images one moment, and then it simply wohn't export the next. The export bar appears but makes no progress. I'm exporting to a folder on my desktop, so nothing fancy. I've even tried exporting directly to my desktop to no avail. I can find the RAW file when I go to "Show in finder", so I know it's there. I can open it, so it's not corrupt. I've updated Lightroom and also reset the settings. I've also reset my computer. I've also made sure there's enough room on my computer to export this photo. What else can I try?

HiWhen you over crop an image you have transparent sections outside the image. when you export these as JPG, understandably it fills that with a colour (as JPG cant do transparent), but it always uses white. Is there an option to make the default another colour, ie black.  saves extra work thanks

Hello, I've seen this problem posted on several forums going back a few years with little resolve. After creating a mask on a photo and after so many edits to the mask, the program begins to lag and freeze so badly that it becomes unusable. 10-30 seconds for each mouse click to register. Click-and-drag functions, like using a mask brush, stop registering entirely.    I’m running on Windows 11 PC. My primary catalog and photos are saved on an internal SSD. Backup is on an external SSD. My computer is about 1 year old (see SYSTEM INFO below.) The problem is with Lightroom Classic only, all other software and OS otherwise run perfectly. This problem occurs with all image types, RAW or JPG. Catalog is backed up/optimized/integrity tested multiple times per week.   Here’s what I’ve tried: - Disable GPU acceleration in LRC (no difference.) - Update NVidia drivers. - Switch between Studio and Game Ready Nvidia drivers. - Run chkdsk from cmd prompt on all drives. - Lower desktop

I use One Drive to backup all the Lrc catalogues plus the recent year's of photos. One Drive is also my backup for all other files on the computer.I mistakedly blocked One Drive whilst editing. I have signed in again outside of Lr but One Drive seems to be trying to sych everything again - a process which will take days and might be wasting storage space.How do I re-establish things? 

I am a long time Adobe user and primarily use the Photography Bundle.  All the apps work but suddenly 2 days ago LRC died while using it. No response it trying to open it again. How do I install a new copy when the computer things it is stll there?  The version was the latest as of 5/24/2025Windows 10, last version.All other Adobe apps are functioning normally.  I went to the Adobe website to see if just downloading a new current version would work, but nothing started. If I can replace the failed version, would I lose the setting data of older edited files?LRC does not begin to load, as if the applicaion is not present, no error messagesThanks for any suggestions!Stan

I do real estate photography and a new work flow proces in my company has discovered a strange behaviour/bug in Lightroom Classic which causes a rather irritating time waste. I use Windows 11, LrC 14.3.1 and Camera Raw 17.3.1.We shoot 3 brackets -3, 0, +3 - I use Fujifilm so I get Fujifilm raw fileformat RAF.The proces is as follows for delivery of DNG-HDR to post production. 1. Convert the bracketed RAW files to DNG resized to 3000x2000px. The converted DNG files retains the lens correction. (this can be done in stand alone camera raw or through LrC - it makes no difference to the end result).2. Import resized DNG to LrC, autostack and merge the resized DNG to DNG-HDR. The problem now is that the DNG-HDR that is created, has lost the lens corrections and it cannot be (re)applied throught LrC. So there is vignetting and barrel distortion visible in the final. My colleagues using Canon, Sony or Nikon do not experience this problem. I and my colleagues that use fujifilm al

Hi,I need a way to remove all or specific metadata that Lightroom puts into the photos first time they are read, specific data that tells LR not to read or import those photos again.I know there are a few metadata handling standalone apps out there, but I don't know if any of them can do this, and preferably all photos in one specific folder.I can't start from scratch creating a brand new catalog as I have over 30000 photos spanning over 20 years and a very complex folder structure and advanced indexing of keywords.The problem is that a certain folder of photos, photos taken last year that I put on a temp external disk, won't get imported no matter what I try. They will show up in import, but only as grey icons, not as greyed out photos. Starting the import just gets me to a stalled process that when I stop it after a minute or after an hour just informes me that it couldn't find the photos. I've moved to other location on same disk (of course won't work) and moved them to the computer

I ask because a friend who is learning to use LRC sent me a screenshot of a message saying "425 photos were converted to DNG." He had just imported Sony camera raw files into LRC. For years, I have been using the DNG converter to convert my camera files BEFORE importing them into LRC. From the screenshot my friend sent, it appears that LRC is doing the conversion automatically. Is this possible? I am attaching my friend's screenshot:

Returning to the books module after a few years, the ability to adjust cells by entering values numerically seems to have disappeared. I have single photos on all my pages, I've adjusted the first cell size & position and now I need to match size and positions to this on all the remaining pages. Not possible to accurately adjust to match so how do I go about this?Thanks.

I develop photos exclusively for web use in Lightroom Classic. That means I'm exporting in sRGB colorspace to post images on my website and social media. However, exported photos look completely different than what I see while developing. I assume this is because Lightroom uses a different ProPhoto colorspace. My monitor is a Dell S2721DGF IPS monitor. It has a wide-gamut and excellent color reproduction, though I have not done any calibration myself.Now, I understand that Lightroom is a color managed program and windows/web is not, therefore I expect to see color differences when exporting to sRGB. I'm trying to use soft proofing to predict the differences and make changes, but the issue is that the soft-proofing doesn't appear to be working correctly. The picture I open in Windows does not reflect the soft-proofed sRGB copy displaying in Lightroom. Furthermore, the soft-proofed copy doesn't appear any different than the original in a side-by-side comparison inside Lightroom. See

I recently went to remove a group of images from my lr classic catalog, as I've done thousands of times before, and nearly all my images were seemingly removed from the catalog. Not just missing with an exclamation point, fully gone with most all my collections saying 0 images. First assumption was I messed up "somehow" in selecting images, but after investigation I found that the catalog size is still larger than my most recent backup. The .lrcat file size of the backup is 2gbs, whereas my current catalog experiencing this issue is 2.2gbs, despite nearly all the images being seemingly removed. I would assume the catalog size would decrease drastically if all the images were truly removed. Additionally, not all the images were removed, there are still ~200 images remaining from across the years.I can restore my most recent backup, but it was from a couple months back as I have a bad habit of skipping until next time while closing LR classic. Due to the mentioned catalog size

Please move to Discussions.Link to post: (Issue with Grayed-Out Files Appearing After Importing Photos) by Mrsemcampbell https://community.adobe.com/t5/lightroom-classic-bugs/issue-with-grayed-out-files-appearing-after-importing-photos/idi-p/15339736 In the last few photo imports to my Lightroom catalog, I've noticed that every few photos, a grayed-out file appears in the grid view. These files don’t correspond to any actual images—they don’t show up in Finder, and they aren’t recognized as missing by Lightroom. It's as if Lightroom is generating placeholder files with no data.     When I try to interact with these files (delete, edit, locate, etc.), nothing happens. Lightroom doesn’t respond to any commands related to them. The real issue comes up during the culling process: if any of these gray files are selected when I attempt to delete unflagged/rejected images, Lightroom throws an error and prevents the operation. I’m forced to manually deselect each gray file before I

Hello gang,Are there any LRC catalog utilities to scan the catalog for any errors or identify any possible issues?

Due to a series of unfortunate issues I'm forced to do a clean install of the Windows 11 and my Adobe products. my old system is still in operation and  I do have a up to date lightroom backup. My question is when I restore with the the back up does cover all the continous lightroom history, file locations and collection settings. or should I save the entire lightroom folder and pull it back once I have the clean install completed?  Second Thought Can I move lightroom to One Drive get it functioning there?

Hi I'm using the html/css/js tool from Adobe Lightroom Classic to generate code for web photo galleries. This is working on desktop, but on mobile I only have the first 5 images and I don't know why. In DevTools all images are loaded and displayed… Would anyone have identified and fixed this issue ? Could be in main.js file or in main.css file I suppose. Also posted this on Stackoverflow, here. (But could only paste the main.js file there, with main.js and main.css I reached the size limit…)

I'm using Lightroom Classic version 14.3.1. I'm on Windows 10, 64 bit. Whenever I import photos from my harddrive to Lightroom, they're significantly more pixelated and noisy than when I view them through the default Photos app on Windows. Lightroom still recognizes the correct dimensions for the photos, but whenever I export them the dimensions drop to 1365 x 2048. My .cr2 files are all between 20 to 25 megabytes but the exported ones are 3 or less. Even with photos I've already edited and exported at normal resolution, if I import those same files again the resolution drops when they're imported now. Anyone know how to fix this?  

When attempting to open, I get the spinning ball for about 5 seconds, and then nothing.Go into task manager, it is listed in Background processes using 0% CPU, not listed in AppsI rebooted,  uninstalled an reinstalled,  Did alt/shift to reset preferences,  checked for windows and driver updates.Nothing I have done so far has helped. I really need Lightroom working again. Any thoughts?

I see so many discussions and feature suggestions for changing the default sort order in LrC going back many years.Lightroom appears to default to capture time.  With our workflow we need to sort by filename.  It's one more step in our process that should be as simple as being able to specify our preference in Lightroom.Am I missing something or does Lightroom really not support sort defaults?

Hi. I have Lightroom & Lightroom Classis on my Windows 11 computer.I keep getting this annoying message. I have done the fix which said that to host file or something was fixed.Is there anything else I can try? The only thing I have not tried was to uninstall everything and install again. But I don't know if a normal uninstall will delete every little bit of adobe on my PC. I have no other Adobe products installed.Thanks. 

Hi - is it possible to adjust individual slide durations to better suit the audio when making a slideshow?LR's "set to music" tab does an OK job but not perfect. Thanks

So, I looked around, seems more have this issue, even with more powerfull PCs. I did a test, with the parallel building on and off. The difference in CPU usage? EXACTLY THE SAME!I timed it twice, on and off, both times in 30 seconds, it only build about 20 previews in both cases.Not seeing ANY difference with it on or off, seems its bugged. I would expect to see atleast some difference. I have to build 4000 previews, this is insanly slow, I need to wait almost an hour to get them build. That's unworkable. It's a 12 core/24 thread CPU, which according to benches is faster then a desktop i7-12700K on multicore benches, which also should be a more then suffcient powerfull CPU.I'm on windows btw, and its the latesest LR but has been always like that. Lightroom Classic version: 14.3.1 [ 202505061331-b063faef ]License: Creative CloudLanguage setting: enOperating system: Windows 11 - Business EditionVersion: 11.0.26100Application architecture: x64System architecture: x64Logical

IMPROVE PHOTOS AND AUTOMATIC NEXT SELECTIONGood morning, I'm Luca  and I use the Lightroom Classic license. I wanted to ask a question. Since I formatted my PC and reinstalled the Adobe package, I had a previous setting but unfortunately now it works the other way around. In practice!!! I click on a photo and I IMPROVE the photo with the button and the appropriate option, when it creates the second image at the end of the process, the photo that the program improved remains selected and the original raw one is deselected. I need the original ones to remain selected at the same time because I can delete them in a second, otherwise I have to select them and find them one by one. Before the formatting, it worked that the created and improved images were not selected, the originals remained selected. Is there another procedure that I can restore to be able to do this?I hope I was clear. Thanks
