Lightroom Classic

Hey everyone! First time posting so be kind ;) Been using LR for over a decade with no issues on an 11yo gen 3 i7. Perfect, never a problem Fresh new pc build with RTX 5070TI and LrC to move into the Ai world.I can go a week or two perfectly, then I get complete pc shutdown when trying to use AI Noise reduction. Studio Drivers installed.  I read that people have issues with this on the threads and stuff. Is it a stability issue with LrC? Do I move to cloud LR? Is it hardware? Is the AI just too new to be stable and this is life?  I’ve reinstalled LR, drivers, optimised catalogues, ensured there’s plenty of storage and ram etc. can’t seem to find the problem Open to suggestions, cause my tearing my hair out!

something has corrupted a LRC file   I can not delete the corrupt file and I can not open Lightroom because it says it is in use.  ????  help please    <removed for privacy>

Can i use Lrc both on pc as well as mobile?

Je suis habitué à travailler en mode connecté directement à partir de Lightroom Classic.J’utilise un Canon 5D Mark4.J’ai fait tous les tests et manipulations recommandées, mais rien n’y fait…J’ai cependant une piste : ce problème est apparu après mise à jour de mon MacOS. Je travaille maintenant avec macOS Tahoe (26.2). Je ne vois que cette explication…Avez-vous vu déjà ce cas ?I'm used to working in connected mode directly from Lightroom Classic.I use a Canon 5D Mark IV.I’ve tried all the recommended tests and troubleshooting steps, but nothing works…I do have one theory, though: this issue started after I updated my macOS. I’m now running macOS Tahoe (26.2). That’s the only explanation I can think of…Have you ever seen this happen before?

I have several catalogs. When I close one catalog and try to open another, the one I've selected doesn't open in Windows 11. I have to restart the PC. Does anyone have any ideas about this? Best regards, Thomy

I've searched in vain for a way to open Adobe Camera Raw from within Lightroom on my Nikon NEF RAW files. While I've read that ACR is built into Lightroom, I specifically want to use the new experimental "Distraction Removal->Remove Reflections" feature in ACR on a number of photos that I took out of a bus window in Cairo a few weeks ago. It works fantastically well.While I'm sure this feature will eventually be included in Lightroom, I want to use it now.  The only way I've been able to do it is to find the image in Windows Explorer and then choose "Open with Photoshop" , which brings up ACR. In Lightroom, "Edit in Photoshop 2025" doesn't enable the feature (I guess it's sending a TIFF or PSD) and "Open as Smart Object in Photoshop" and then choosing the Camera Raw filter doesn't enable the feature either -- says "wrong file type". Is there a .EXE for ACR that I can choose in Explorer, or add as a second "Edit in..." option in LIghtroom?  Or should I just wait for Li

I don’t know if it’s a bug or just something Adobe has to fix, but I am so utterly disappointed in the AI denoising feature in LrC.  What’s worse is that I’ve seen it evolve over time.  When you first implemented it, it was really inferior to other offerings.  Then it actually got good for awhile.  But now… it’s like it’s hallucinating and adding the wrong details to images.  If I turn it down, it doesn’t even denoise well.  As soon as I turn it up, it starts sharpening edges and adding weird swirls in facial hair.  It makes my pictures look like an AI generated cartoon.  I’ve been forced to go back to DxO Photolab to denoise stuff.  Not only that, but DxO can literally denoise a stack of 20 photos in the time it takes LrC to do one.  This is just unacceptable.  You can do better.  Please fix this ASAP.  

I worked with smart preview and used super resolution. This left obvious artifacts in form of grid.They do not go away when I have RAW available, I discarded smart preview, and even when I disable and re-enable super resolution for that file. (Without super resolution this grid is gone.)Artifacts are even visible in exports.These artifacts do not appear on very similar photo with same edits, but which was never edited as a smart preview. 

It is fantastic there is an option to create your own templates, but not everything is saved unfortunately. 

I managed to desync my folders from lightroom classic and have lost all my edits in progress, and edits made ready for export. Is there a way to restore this?

I’m done with this. With every single update, Lightroom becomes more of a mess. Now, out of nowhere, the brush tool and masking have completely stopped working. I can't get any work done.I have already tried all the standard "fixes":Toggling GPU acceleration on/off - no effect.Restarting macOS and Lightroom multiple times - no effect.Resetting preferences and clearing cache - still nothing.And don't even try to blame my hardware. I am running this on a Mac Studio M1 Max and a MacBook Pro 16 M1 Pro. The exact same issue occurs on both machines after working for a while. This isn't a hardware limitation; this is your buggy, unoptimized code.I posted about this exact problem months ago in this forum, and nothing has been fixed. You keep charging a monthly subscription fee, yet you fail to provide a stable environment for basic functions like masking. This is my last year with Adobe. I am officially looking for alternatives that actually work and don't waste my time and nerves.Fix your sof

I shoot with Sony a7v and Sigma 35mm 1.4 dg dn II. On may 22th 2026 I have updated  LrC and Camera Raw, which include the lens profile for this Sigma lens (verified archive .lcp into the folder lensprofile>>1.0).The Raw files taken with this lens edited in Lrc comes with “built in” profile, but when I try to change to custom and select Sigma 35mm 1.4 dg dn II (A026), it doesn’t show up, and when I select “auto” it selects a different lens.How can I solve this?thanks a lot,kind regards,Pablo 

I constantly have to tick 'photo comment ' away, it pops up at random or whenever you click on the photo frame. Does anyone else has this? 

There are some nice predesigned borders, but you cannot adjust the size or the position. Could that be made possible? 

i have a folder with a subfolder named MLS. when i exported images to it, i mistakenly entered “mls” (i.e. lower case. LrC dutifully created a subfolder labelled mls, and it now shows two subfolders: MLS and mls. i tried to move the image from the latter to the former but LrC wouldn’t do itWindows File Explorer only shows one subfolder: MLS, with all the images

I re-edit a photo from Lr Classic in Photoshop. It is in my target collection which is my sync collection. Lightroom Classic says the sync is done. The new version is visible in Lightroom on the web (Chrome). The thumbnail in Lr Mobile is correct. When I open the image in Lightroom Mobile it reverts back to the old previously edited version. Thanks

I have a book of multiple pages, and I need 10 pages to change place to another book. The only way I found so far to do this is to export the whole book to pdf, and put 10 pdf pages to the other book. But the problem is, you cannot change anything anymore (as it is a pdf and not the different photos). Is there a way to drag whole pages  from one book to the other, so if you would drag them, the photo’s and the layout on the page go as well to the new book? 

The only solution i have found is to open the photo first in another module, then go back to the book module, then add the photo in the book. But this takes extra time. 

I have a 5TB image folder on one external HHD. (Catalogues are on my internal SSD) The drive is showing signs of possible failure so I have split the images onto two external SSD for safety. (Also backed up twice) I used the same naming structure for the nested folder. Combined they have all the folder/images of the orginal drive. Is there a way to point the catalogue to these two different drives?Drive A (failing) Images_africa_32 nested foldersDrive B  Images_africa_12 of the 32 foldersDrive C Images_africa_20 of the foldersIn the Lightroom panel, if I choose the 12 folders on drive A that match Drive B and do Update location. And then chose the 20 and update location to drive C, will this work? Can it point to the two drives? I tested one folder and it seems to work, but before I do everything, I just wanted to see if I was handling this correctly?Any assistance would be very welcome. ThanksNancie   

When Soft Proofing viewing the monitor gamut warning just change the entire display area to red. Note this also happened in 15.3. Destination gamut warning works correctly.Windows 15.3.1 release, everything up to date. 

I purchased my sony a7V in February 2026 but the raw files are still not supported by LR classic. I was on the phone with your support twice this week. Although I’ve read online that LR classic now supports these files,  a supervisor from Adobe told me yesterday that it is not so.  Please get this update for us  asap - us Sony users feel left behind. I have 2000 photos not supported by LR and had to go back to using my A7iii until you update. thank you

When clicking on the Remove Section before it would automatically open all the Remove tab (as there wasn't a Distraction Removal tab) however now it's automatically closed and just means having to click on the Remove tab. I much prefered it before, as now it just means 1 more extra click! As there's only 2 sections in the Remove tab then it may as well just have both open.
