Lightroom Classic

Hello,I have a catalog with around 30k images, for which the .lrcat was stable at around 60Mb in size, and which gets backed up automatically into a Dropbox folder.A few days ago, the size of the .lrcat file suddendly jumped to around 400Mb. I'm not talking about the previews; just the catalog. When LC exits and backs up, even the compressed zip file that I archive on Dropbox is now >170Mb, which just isn't practical.  Does anyone know of any recent changes that might have caused this? I am discarding 1:1 previews daily.Any ideas gratefully received, (Am on MacOS 15.7.2 running LC 15.0.1 with everything on an external SSD drive.)

LRC V-15 Reflection Removal in the Remove panel is not working. It starts the process on the first image for approx 10 seconds and the progression bar ends with no result. When I make a new attempt, on a second image, the progress bar vanishes within less than 1 second, and nothing happens. No account in History for attempting this action either. If I exit lightroom, when I return, and make another attempt, it will try to complete the process, but then fail. It will not give it a try on the second image, and the preview of the first image is stuck in the view area when I move on the film strip or with the keypad to another image. Inorder to view a different image I must refresh the view system by switching to Grid and then back to Loupe.  I am working on a desktop PC. I have attached one of the images I tried to process with Reflection removal , as well as a screen shot of my components on my PC. Is this a Bug? or is my system deficient?

HiI want to import duplicates and this has been working fine forever but today I am getting grayed out images even though I have the duplicates box unchecked.  It's like it has stopped working and is still not importing duplicates even though I have it deselected.  Was there a software update and this is a bug?

Hi everyone, We're excited to announce a new Adobe Community experience is coming this January. A little bit about the update:The new experience will be simpler to navigate, make it easier to connect with other creatives and Adobe experts, and will give you clearer ways to share feature ideas, enhancement requests, and bug reports—with greater visibility into their status with our product teams. In the meantime: Adobe Community will remain active. Keep using it as usual—there will be no interruption in access. In fact, you’ll notice even more Adobe Experts on deck to provide faster responses before, during, and after the update. No existing content will be lost in the update. Every single post, reply, solution, feature request, and bug report you’ve made will be transferred to the new experience. You won't need to recreate anything. Existing content will reappear in two phases. When we launch the new community, all posts created on or before November 16 will be there from day one. Aft

Hi everyone, I’m encountering a significant issue with the HDR Output workflow in Lightroom (macOS) that seems to specifically affect blue tones in the highlights, particularly skies. The Problem: When editing RAW files in HDR mode, if I use a Camera Matching Profile (e.g., Camera Standard, Natural, etc.) instead of an Adobe Color profile, increasing the Exposure slider causes blue highlights to become unnaturally oversaturated and "neon-like." As the exposure goes up, the blues undergo a severe hue shift and lose their natural gradient. Test Environment & Findings:Cross-Brand Issue: I have confirmed this behavior with RAW files from Sony, Nikon, and Hasselblad. The result is consistent across all three brands.Comparison with OEM Software: Interestingly, when I process the same Hasselblad RAW files in Hasselblad Phocus with HDR enabled, this issue does not occur. In Phocus, the blues remain stable and natural even when pushing the exposure, whereas Lightroom seems to

I am running a Windows 11 and I am using Lightroom Classic 15.1. Just recently, getting to be a regular thing, when I want to rename a file I get a warning that the file cannot be renamed because it either missing or not writable. The file next to it, no problem. The file is there, no question, so what makes it not writable. I'm not doing anything different that I have in the past. Your help is appreciated. Thanks. 

Hi, I have had this problem already a few times:I imported some files from a folder and the day after when I am going to the catalog to see again the pictures, I receive this problem: This means that Lightroom says that there are no pictures in the selected folder! While there are 517 pictures in it already imported.I had to make an new folder to import them again and there they are stil in it.I work in Windows 11 with Lightroom 15.01 Can anyone give me an idea to solve this problem? Thanks anywayMarc Dooms (Belgium)

A partir de la version 15.0 de Ligtroom crea una extension acr. junto a xmp. por defecto.Para grandes lotes de edicion (miles), en mi caso, donde los ajustes son basicos de color y recorte, es un problema tener que gestionar el volumen de extensiones .acr que entiendo no tienen utilidad, si no me equivoco.¿Es posible disponer solo de las extensiones .xmp al exportar el Raw con los ajustes básicos que he comentado?Gracias!

I backed uo my LR catalogue yesterday and now the folders show as empty in LR, the pictures are still on my hard drive in their correct folders

Ive just got the new version, as I was away from my computer for a while.  I importet a bunch of Tiffs as well as some NEFs from my SD card. In both cases LrC doesnt create the previews, the sqaures in the gallery just stay grey. If I switch over to the dev module the image shows, and i believe it also renders a preview. The preview shows also then in gallery, but only for 3 images at a time, if i click a fouth one, the first one turns grey. Very weird.  Also if I try to force new previews, the progress bar just wont move and nothing happens.  Old previews are fine. I've also tried deleting the preview file, but didnt change anything. Setup and everything is the same.  Running on a MBP 2018 on 16GB Ram and Sonoma. Is maybe that the problem? Is Sonoma not supported anymore? If so can I revert back to an older LrC version? Help, please?

For some reason, importing the first folder for the new year, which should be showing in library inside the folder for 2026, came in showing the 'originals' folder outside on its own and not properly nested. How can I fix this?

I am running a Windows 10 PC with a 2TB SDD, with 400GB+ of free space on it.  I had a problem with my catalog a week ago, and Sameer K helped me get the catalog open, resetting my preferences.  Since then, however, Lightroom is exceedingly slow. When I open an image from the filmstrip using loupe view, it can take up to 15 seconds to open it.  The problem is worse tryimg to enlarge to a 100% view; the average time takes between 18-26 seconds.  Both these issues are new; it used to take just a few seconds to open and enlarge images when I was using my previous catalog. I have cleared my cache, but both problems existed before I did this, and still exist afterwards.  I have my cache set to 20GB.   Can anyone suggest any remedies to speed up the program?   Paul Lebras

Working on MacOS Tahoe 26.1 My Lightroom keeps crashing when I'm working on some of my catalogs (usually larger ones). This started about a month ago with the Tahoe update. It only affected 1 catalog in the beginning, and now another one of my catalogs is crashing continuously.  Lightroom is updated (uninstalled and reinstalled). I reset preferences and tested the integrity of the catalog. Turned off "hover previews". De-selected "Use Graphics Processor".  I have no idea what else to try, please help!

Using the following LrC 15.1 and PS 27.2 on macOS 15.4.1, "Edit PS" no longer works. This is very frustrating and unacceptable. It should work day in, day out. What do I do to solve this?

It's been a while, and i posted a couple of times, but unfortunatly no group expert replied or helped to figure out the issue. Please advise what i can do. This was such an expected feature, and now it's totally useless for me. Before and after are attached. Mac OS- 15.6.1LrC- 15.1Camera Raw- 18.1.1

A big userbase for Lightsroom (and Photoshop) are the vast community of photograpers associated to FIAP (La Fédération Internationale de l'Art Photographique) or PSA (Photografic Society of America).In a newly issued breif, FIAP and PSA have stated what use of AI support allowed when particapating in photocompetitions around the word associated to theese two associations.  THis means that all theese users need to know in detail what use of LR (and PS) can discualify them in competitions.https://drive.google.com/file/d/1Vnvyl0jFJW8JP_tvKpFNGiESLLd5REsq/view Prohibited are the use of:"any AI-assisted processes for synthetic imagegeneration that incorporate external image data, visual elements, textures, objects, orscenes not originally present in the authors photograph are prohibited." It is intuitive that functionality like "generative fill", and other functions named "generative..:" will be covered with this, but what about AI-based "Adaptive presets".&nbs

I am reporting a persistent crash in Lightroom Classic 15.1 on Apple Silicon (Mac Studio M1 Max). The application crashes immediately when using AI Masking (Subject/People) or the Brush tool. Troubleshooting attempted: Reset Preferences: Fixed it for 1 day, then crash returned. GPU Acceleration set to OFF: CRASH PERSISTS. This confirms it is NOT a GPU/Metal driver issue. I have analyzed the Crash Report. The crash occurs specifically in the CameraRaw framework (Thread 75), throwing a Segmentation Fault (SIGSEGV) due to an invalid memory write attempt. This indicates a bug in how the Camera Raw engine handles memory/buffer allocation for masking on ARM64 architecture in this specific release. Here is the relevant Stack Trace from the Crash Report:  Process: Adobe Lightroom Classic [16777] Identifier: com.adobe.LightroomClassicCC7 Version: 15.1 (15.1) Code Type: ARM-64 (Native) Hardware Model: Mac13,1 (Mac Studio M1 Max) Exception Type

When I add a caption to a photo in Photoshop, then save back to Lightroom Classic, it saves a grey screen. I have tried 'save as' and get the same result. I don't know what else to try. I am using a. Macbook Pro with Sequoia 15.7.3.

Hi everyone, I have a workflow challenge that I believe affects many users working across multiple locations with different Adobe accounts. My Situation: I work on photos at two different locations: Location A: Using Adobe account A (family member's subscription) Location B: Using my own Adobe account B When I edit photos at Location A, there's no practical way to sync those edits to my Lightroom Classic installation at Location B. What I've Tried: Yes, I know about "Export as Catalog" - but honestly, this is too cumbersome for regular use. I'm looking for something more seamless. What I'd Love to See: A way to sync edit metadata between Lightroom installations without going through the browser-based cloud interface. Something like: Lightweight export/import of develop settings that works across catalogs and accounts A "share edits" feature between linked accounts Or simply: CC cloud sync that works across accounts within the desktop app Why This Matters: Multi-location workflows with

  I have a new mac mini and have transferred everything over from my old imac.  I downloaded the installer for lightroom and creative cloud.  I have dragged my LR5 which transferred over from the old computer to the trash and emptied it.  When I double click the installer icon nothing happens - no error message - nothing - it will not start the install.  I have also tried restarting my mac mini.  What can I do or who can I talk to about this?  Is there an Adobr support number I can call - I'm very frustrated and losing days on my free trial version.

I've used Bridge for years, but it seems that with later cameras, like the Nikon Z9 it does not show thumbnails of nor play videos, unless there is some secret I don't know about.  I've never liked Lightroom, but I found that it does show theses thumbnails, which would make it much easier to add desired metadata without having to use free programs like Nikon Studio to show or play the video.  So I was trying to test how compatible the 2 program in the title.  I see that LR shows my entered metadata, and keywords.  but I also saw that it had dates for the videos, which bridge lacks.  I tried exporting a file with the date and also added a keyword, saving with the same file name and location and checking back to see the file in the same folder in Bridge and nothing new added.  Is there someone familiar with both programs who can explain why this is so.

I cannot publish any more (windows), the error message is not very helpful! Newest version of LR & plugin.   [Moved from ‘Bugs’ to ‘Discussions’ by moderator, according to forum rules. You cannot file a bug report for a third party plugin.]
