Questions

When I create a new collection in Lightroom Classic 15.2 in order to sync photos from my Mac to other devices (iPad + iPhone), sometimes none of the photos will sync, sometimes a couple only will. What is strange is that if I stay in the Collection folder and make a virtual copy of an “unsyncable” photo and make edits to it, that virtual copy will get synced, but the original photo will remain unsynced. When I look at “diagnostic” in the Synch section of the settings, all it will say under “Error/Synch details” is “Image”, which is not helpful at all. I’ve tried rebuilding the sync data more than once, but it didn’t work. I never used to have sync problems before 15.2, so I hope this can be fixed. Thanks!

Until this evening, I had 12,000 photos of my recent trip to Tanzania on Lightroom Classic. When I initially imported them, for some reason they imported to a folder on my desktop. However, I decided to go with this and have been editing without any issues. Today, when I went to edit some more images, it turns out that 11,000 of my photos now have missing originals. When I tried to locate them, LRC told me that the photos were in the folder on my desktop. However, most of the files have disappeared from that folder. For example, for one date when I have almost 3,000 thumbnails, there are only two remaining files in the folder for that date.  I don't know if this is an issue with LRC or with my imac, but the original files can't have just disappeared into thin air. Or can they?? Obviously, I am desperate to get them back!

Hi everyone!I hope I didn’t miss any already existing bug / issue posts for this issue. Here’s the short version again:After upgrading to Lightroom Classic 15.2, I experience an increase in repeatable and reproducable freezes with following crashes. These occur always when zooming into an image and are instantanous. The resulting CrashLog from the error report tool is attatched as well as the Lightroom System Info sheet.  System spec overview: Windows Desktop PC (custom)OS: Windows 11 25H2 Build 26200CPU: AMD Ryzen 9 7950x3D (+ integrated iGPU)GPU: NVIDIA RTX 4070ti (12GB GDDR6 VRAM) [591.74 - Driver info see below]RAM: 64GB DDR5 6000MTs CL30DISK: LRc installed on M.2 Gen.4 SSD; Library on same drive; Media on 7200RPM HDDVER.: Adobe Lightroom v15.2First observations:Since version 14.1, I have encountered random issues, from increased stuttering to freezing.

Here is a screen shot of the problem. All I am doing is selecting remove. The others disappear, switch to Library and back, and they all reappear.

I’m getting the “AI Edits Storage Error” in Lightroom Classic, and I’ve already followed all the steps listed on Adobe’s help page, but the issue is still happening.Here’s what I’ve tried so far: Confirmed there is enough free disk space Restarted Lightroom and my Mac Ensured only one instance of Lightroom is open Gave Lightroom Classic Full Disk Access and Files & Folders permissions in macOS Verified my user account has Read & Write permissions Checked that the catalog and .lrcat-data folder are accessible Not using any cleanup tools or cloud sync on the catalog while Lightroom is open Despite all this, the error continues to appear and AI edits fail to save properly.

Problem exporting pure grayscale RGB files from Lightroom ClassicHi everyone,I’m preparing images for a photo book and ran into a problem with grayscale files.For printing, I need RGB files that contain only neutral gray values (no color information) in order to avoid any color cast in the final print.Some of my photos were edited in Adobe Lightroom Classic and currently use a Color profile. When I switch the image to Monochrome or choose Black & White in Lightroom and then export the image as a JPG, everything initially appears correct.However, when I open the exported JPG again, the file is still in color mode, not a true grayscale-only RGB file. In other words, it seems that Lightroom still exports an RGB color file with potential color channels instead of strictly neutral gray values.This happens regardless of whether I overwrite the original file or export the image under a new filename. use jpg or nef  My question:Is there a way in Lightroom Classic to export RGB files th

I have just upgraded to lightroom version 13.0.01, the photo import is painfully slow. I started importing 30 photos at 9 am, it is now 09:47 and less than 15 photos have imported. any ideas? I have already carried out a restart of the PC to no avail (that was pre 9am). I should point out that I have never had a slow photo import problem before this version.

This post applies to Camera Raw and Lightroom Classic.   Dust Removal is no longer in Early Access status and can be found in the Remove edit panel for Camera Raw & Lightroom Classic. Dust Removal helps with removing distracting spots on an image that may be caused by dust on a camera's sensor.   Once enabled, your image will be scanned, and any detected dust spots will be automatically removed using Content-Aware Remove. For refinement, you can select one or multiple spots to delete or refresh. Batch removal is also supported; simply select the "Dust" checkbox under "Remove" in the copy settings dialog.Please note that scanned negatives are not in the scope of this feature at this time.    Dust spots on scans tend to be located in the focal plane, with the negative and very sharp, while sensor dust is typically positioned out of the focal plane and therefore not in focus. Scanned negative dust typically appears as white spots on a darker backgro

  How to provide Full Disk Access on macOS   Since macOS 10.14 (Mojave), Apple introduced a new privacy structure to help ensure that all applications obtain user consent before accessing documents, downloads, desktop, iCloud Drive, and network volumes. This has been reinforced in newer versions of macOS. This change prevents unauthorized access to user files and folders. When Full Disk access & Accessibility permissions are needed, users may be asked to or be required to change the setting in System Preferences > Security & Privacy > Privacy for Lightroom Classic manually.    While for the File & Folders access, the user is prompted to allow or deny when needed.    Why provide full disk access to Lightroom Classic? Insufficient or broken permissions may restrict Lightroom Classic from functioning correctly and break your workflows. All tasks that require access to the computer's storage — importing/exporting images, cross-app w

Tried everything as I really like these presets they are working on the app on my Mac but when I edit on my phone the app is glitchy and the auto + retro filters will not apply to any of my photos 

Lightroom Classic silently skips files during batch export if it fails to write Credit/IPTC metadata. Additionally, it misreports local file errors as network issues.Steps to reproduce: Select a batch of images (e.g., 120 files). Export with a metadata preset that includes Credit/Copyright info. Observe that some files are randomly skipped. Actual Results: Only a portion of the files (e.g., 106 out of 120) are exported without a proper per-file error log. A "No network access" error pops up mid-export despite a perfectly stable internet connection. The export engine deletes the entire image file if the metadata write operation fails, instead of just skipping the metadata and saving the image. Expected Results: Lightroom should export the image even if metadata injection fails (best-effort export). Errors should be accurately reported (local I/O failure, not "No network access"). A detailed log should show exactly which files failed and why.  

This post applies to Lightroom Classic and Lightroom Desktop.  Feedback for Camera Raw should be posted here.   Update February 2025:Adobe has introduced two Adaptive Profiles – Adaptive Color & Adaptive B&W.   Getting started with the Adaptive Profiles:  Access a profile inside the profile favorites menu.  In addition, there is a new section for Adaptive Profiles in the Profiles browser.  Enable the profile and adjust the ‘Amount’ slider as desired.  Use the rest of the Camera Raw tools just like you would otherwise.  Check out the Help Page for more detailed usage information. For more technical information on the underlying technology, please refer to this blog post.    Please try the profiles and share feedback in this community forum thread. It would help to include details like how you access Camera Raw (via Adobe Bridge or Photoshop), your computer system details, and as much information as possible about

Hi Adobe Team, I’m posting this as a clear performance regression report for Lightroom Classic v15.x — specifically the Develop module image-to-image switching latency on Mac. REALLY SLOW. Please do not merge this thread into a generic “performance” megathread and then mark it as “Solved” as if nothing happened. Multiple users are reporting the same behaviour, and it deserves a proper investigation and acknowledgement (instead of being dismissed as an “NVIDIA driver” issue — this is Apple Silicon). What’s happening On Lightroom Classic v15.2, switching between photos in Develop is several times slower than in previous versions. This is not a minor “feels slower” issue — it’s a real, repeatable regression that drastically impacts professional workflows. My setup  MacBook Pro (M3 Max) macOS v26.2 Lightroom Classic v15.2 Preferences → Performance → Graphics Processor: ALL acceleration options manually enabled (not Auto)  Proof / Reproduction To remove any subjectivity, I recorded sc

Since updating to LrCC 15 yesterday (Windows 11), I find my workflow much slower. Both the library and develop modules are slower, photos taking a long time (a couple of seconds) to paste settings in the develop module (despite LRCC receiving the input to paste immediately, the effects take a few seconds to apply to the image - this is true across both my Phase One tiff/raw files and my Fujifilm X series raw files).   Anybody else experiencing some slowdowns (as usual with a new LRCC release, unfortunately). 

Every time the user performs any of the following actions in the Develop module,the application becomes "Not Responding" for 3–5 seconds before resuming:  • Collapsing or expanding any panel (Basic, Tone Curve, HSL, Detail, etc.)  • Switching between tools (Crop, Heal, Masking, Object Remove, etc.)  • Switching from Develop to Library module and backThe freeze does NOT occur when:  • Navigating between photos (Next / Previous)  • Adjusting sliders within an already-open panelThis is a clear regression. The behavior was not present in LrC 14.x.The issue was first reported by many users with LrC 15.0 and was NOT fixed in 15.1 or 15.2.I performed detailed diagnostics with Claude Cowork; a full user-mode process dump was captured during an active "Not Responding" freeze and analyzed with WinDbg using the Microsoft public symbol server.Root cause was identified via WinDbg analysis.When any panel or tool transition occurs in LrC 15.x, the substrate event system spawns approximately 60 parall

Hello everyone! I am in a bit of a pickle, and I'm wondering if anyone can help me. I have two computers, one desktop (which is hwere I editmost of the time due to its massive screen), and a Laptop, which I only use to edit when I am not home. Note that I have my catalogs and files always in an external SSD, so I can easily switch from one computer to another.Recently I was traveling, so I opened the catalog on my laptop, and I received a promt to upgrade the catalog for compatibility, which I naturally did and proceeded to work, however, when I came back home and wanted to continue working on my desktop, I got an error message saying that “the catalog cannot be opened because it’s too new to be used by this version of Lightroom”. The issue is that I cannot upgrade Lightroom on my desktop, because the newer versions of Lightroom are not compatible with my MacOS, and I cannot update my MacOS anymore, because my Mac is old… So, I have two questions:1. It seems like Lightroom did not crea

When I launch adobe Lightroom on my windows desktop, I keep getting a system error because of a missing file mcf140u.dll. I already reinstalled Lr twice and restarted my laptop several times. The missing file is present in my windows folder. Does anybody have an idea how to solve this? kind regards, Bastian

I’ve been editing in HDR in LightRoom Classic for a year or two.  I create collections and sync them.When I open these collections with HDR photos in the Lightroom app on my M4 iPad Pro, these image look terrific, the highlights pop, bright and vivid.But when I play a slideshow of these collections, the photos aren’t in HDR like when I open these collections photos manually.Either in slideshow mode, they open SDR versions or maybe the slide show transitions too fast for the HDR metadata to be rendered?When I open them manually it takes a second or two for the HDR effect to load for each file. Beyond editing and viewing HDR photos in LightRoom Classic or the app on devices with HDR displays (or what Apple calls XDR displays), what other software can display HDR properly?  I’m enticed by the Studio Display XDR which Apple just shipped.  But hard to justify that price unless I can display HDR content as slideshows, screensavers, wallpaper, etc.

I’ve been using Lightroom for over a decade. Recently, I’ve toggled something and I now no longer have the option to select Fit, Fill, or Zoom % from the Navigator pane. I’ve gone to window to ensure it’s checked, etc. I have the thumbnail, but no drop down arrow. I’ve searched all over for the answer but haven’t found any other poss with a similar experience. Is this a bug? Please help!
