Lightroom Classic

Description of Issue:Merge to HDR stalls (application unresponsive, beachball) when merging exposure-bracketed images on 15.4.1. Another user in an original 15.3 thread reported this resolved after updating to macOS Tahoe 26.5. I am on macOS Tahoe 26.5.2, a newer build, with a fresh OS install, fresh Creative Cloud install, and a brand-new catalog, and the stall still occurs on 15.4.1. This rules out the macOS-update fix reported by others for the 15.3 version of this issue.Lightroom Classic Version Number: 15.4.1 (Help > System Info)OS Version Number: macOS Tahoe 26.5.2Camera Model: Sony a7r V & DJI Mavic 4 ProComputer Version: Mac Studio M3 UltraStep-by-step Reproduction Instructions:Fresh macOS install, fresh CC/LrC install, no plugins, brand-new catalog.

I moved a folder from one hard drive to another and Lightroom is throwing me in a loop. I’m at a loss, I don’t know what to do here! This makes zero sense I’m going in circles.   

As the title says the folder where my Lightroom catalog is stored only shows the folder 0 to 9 and A to F. In these folders there are seperate folders (like 0A2A). Is there a way I can rebuild/restore my catalog?  It is not showing any .lrcat / .lrdata files.

I am currently on LRC 14.4 and CR 17.4.  I have learned to work with the changes in the Denoise that got rid of the middleman DAT file and keeps the file naming of the original file.  I have learned to batch edit with pasting dev settings including denoise.  It has been ok. But now Adobe doesn't like that I'm running so far behind.    After having this version stable for several months, I am hesitant to upgrade.   Can anyone who has upgraded to the latest version give me any advice?  I only have a 1T harddrive, that I try to clean out by moving files to external SSDs as much as possible.  I am honestly scared to upgrade after seeing so many performance issues, etc from other posts.  I have 13th gen Intel(R), 32 DB RAM, and 8G Nvidia GeForce RTX 4060 Laptop GPU - ASUS TUF Gaming laptop Thoughts?  I can’t really afford a new laptop, so I am hoping to not have to do that again.  Right now, with 14.4, a single denoise takes about 4-8 seconds.

I use DJI drones, and their RAW format is DNG. Lightroom Classic is quite happy to accept these and successfully does an HDR merge on them. The output is once more DNG (or allegedly is).I use Topaz Photo to pre-process my images before doing most of my processing on Lightroom Classic. Topaz quite happily accepts DNG files straight from the drone. However, if I pass it a DNG that HDR Merge has generated, Topaz rejects the image as being an unsupported format.So it looks as if LRC is generating DNG files that do not quite meet Adobe’s own DNG specification in some way that neither Topaz or I understand.I use Windows 11 and the very latest LRC.  

Problem: LrC 15.4.1 - Receive “Lightroom has encountered an issue updating AI edits” & “unable to backup catalog error” after migrating catalog from Windows 10 to Windows 11.  =============== Background: Problems started when I moved LrC catalog/workflow from a windows 10 machine to a windows 11 machine. Backed up entire C drive from W10 PC to external hard drive (included the then-used LrC catalog). Signed out of all adobe apps on old machine before doing a “fresh”/”clean” install of Windows 11 to C drive. Kept all jpg/raw originals on F Drive, which on second catalog import attempt, had no issues on Windows 11.  Migration Attempt 1 (Failed, Abandoned): After Windows 11 install, and LrC install, tried to open old catalog from Windows 10 and could not get it to boot properly. Tried to copy the Catalog from old Windows 10 C drive (external) to new Windows 11 C drive (internal) --- Alt+Open LrC and selecting the copied old catalog led to: missing files, missing edit info, and AI Edit

When I start Denoise, instead of pop-u showing the progress the entire right side panel is grade out and a test says : An AI process is running on the photo. Editing is temporarily disabled.” Ok, There is a problem: A popup is the standard established way of visually indicate a process i progress. The ways this new bizarre way indicates the process is confusing. Sometimes the images flickers, making an optical indication I am Done , I click on something, but there is no response to anything because the process is in progress. Please stop the foolishness.  An example, a 45min running “dead process” on a 24 Mpix file: Even a sniping tool of Windows often hangs when Lightroom runs. The top apre aof the image shows a black background panel, which than disappears. and we cannot even make screens hot, because the entire windows hangs than hopelessly.  An example:Forever hanging, never finishing. A 20Mpix, small by present times. 

Lightroom Classic’s secondary display selection keeps switching from my preferred monitor to another connected monitor. This interrupts my editing workflow and forces me to manually reconfigure the setting.I use a three-monitor setup. Lightroom Classic runs on my left monitor, which is Windows display #1. My preferred secondary display is Windows display #2, the middle monitor. I use that screen to review crop changes and overall edits while working in the Develop module on monitor #1. However, Lightroom Classic randomly changes the secondary display to Windows display #3, and I have to go back into Preferences and set it again.This has been happening for years, and it occurs multiple times within an hour of editing. The repeated reconfiguration breaks my focus, and my current workaround is insufficient. I’m asking Adobe to confirm whether this is reproducible on their side.Steps to reproduce Open Lightroom Classic. Use a three-monitor setup. Set the secondary display to Windows di

When I paste settings threw Auto Sync. The AI processing will start. After while if it is multiple pictures like 30+ it will get stuck on Information "AI processing is in progress for this photo. Editing is temporarily unavailable." Even though the progress has already ended. So no proces is running. Obviously the photo can not be edited so I need to restart lightroom. Can you add some function to stop the proces on the photo itself? Otherwise I can not do anything with it.

SummaryLightroom Classic’s built-in catalog backup takes approximately 14–16 minutes to create a 39.1 GiB ZIP containing 39.7 GiB of nearly incompressible .lrcat-data.I tested the same catalog with two local internal storage destinations: WD_BLACK SN850 1TB, PCIe 4.0 NVMe NAND SSD Intel Optane SSD 900P 280GB, PCIe 3.0 NVMe 3D XPoint Changing the destination from the SN850 to the Optane 900P reduced the duration by only 105 seconds, or 11.24%. The completed ZIP remained approximately 39.1 GiB.The main issue is that almost the entire backup consists of .lrcat-data that provides very little compression benefit.Actual resultsWD_BLACK SN850 destination Source catalog: D:\Lightroom\Lightroom Catalog.lrcat Backup destination: same physical WD_BLACK SN850 Completed ZIP: 39.112012 GiB Backup folder creation to ZIP last write: 15 minutes 34 seconds Intel Optane 900P destination Source catalog: same catalog on the WD_BLACK SN850 Backup destination: separate Intel Optane SSD 900P Compl

Boy, do I need help! I'm 87 years old. I'm loosing my ability to use Adobe products, but want desperately to complete uploading my You Tube channel and need to use Adobe. I live in Kalamazoo, MI. Will some one out there help me over this hump? 

Hi Adobe Support,Since updating to Lightroom Classic 15.4.1, a large number of my Develop presets have disappeared from the Presets panel.My systemLightroom Classic: 15.4.1 Camera Raw: 18.4 macOS: 26.5.2 iMac 2020 Same Lightroom catalog I've been using all year (2026.lrcat).The issueAfter updating Lightroom, I was away for a week. When I returned, many of my presets were missing. The preset files (.xmp) are still present in the correct Settings folder. If I try to import a missing preset, Lightroom reports "Already Imported", but the preset still does not appear in the Presets panel. Some presets from the same collection are visible, while many others are not.Troubleshooting already completedConfirmed I am opening the correct catalog. Created a brand new test catalog – the exact same presets are still missing. Verified the preset files exist in: Catalog Lightroom Settings folder. CameraRaw Settings folder. "Store presets with this catalog" has been tested. Checked Manage Presets – th

I recently updated Lightroom Classic and Photoshop 2026 (27.8) I have Windows 11, My lightroom edit in choice to PS will open photoshop, it informs me to PS2026 not installed, once it connects, then keeps asking me if I want the program to change setting, Then the actual image to edit does not transfer across to PS, I have deleted both apps and re-installed, same issue.

Lightroom Classic on Win 11, 32GB RAM and a hobby photographer.I see on my Catalogue I have been using LR since 2008. I mainly (±80%) shoot wildlife. Ever since then I have shot in RAW with my Canon cameras which saved photos as CR2. I've always imported them: Copy as DNG. I must have done a tutorial those days telling me to do it like this.I now also have a Nikons Coolpix P950 and shoot in RAW as well.What is the best/recommended way to import RAW photos so I can make fulle use of all AI and other presets? I only use LR Classic for photo editing.Thanks.

Hi all. I’m on a M3 MacBook Air running macOS 26.3 and using  LR classic v15.2 with Camera Raw up to date at 18.2.1.My problem is that on one of my external SSDs, a 2TB Samsung T7, LR will not show the photos. In grid mode it will show empty thumbnails with meta data, like star rating, but no previews. In develop it will show only the background color.I tried building previews, both standard and 1:1, via the menu for individual files, for a group of files and for all files. The progress bar appears but does not move at all and no previews of any kind are created. I tried creating a new catalog and copying the files to another T7 SSD and creating a catalog on that, but that did not work either. The drives are all exFAT formatted. The catalog lives on the drive.I’m confused especially because for other photos, I use the same setup and it works well.The photos and folders were originally created on an HDD drive on windows and then also on windows 10 copied to the SSD and used on the SSD o

I have tried everything to delete Select A Source dropdown when importing an image(s):  a question in a browser or a video.  Nothing because they do not address bulk deleting.Recent Files: (Desktop)  You will see a box. Scroll all the way to the bottom.  There is a prompt: Clear Recent Paths.  Click.  They’re gone!

I am backing up my lightroom catalog and it's been 15 hours so far. Is that normal for a catalog with 170,000+ images on lightroom? Should I restart my computer or will that corrupt the catalog?

Further I initially had around 160,000 photos; now I have 390,000 photos.How did this happen and how can it be repaired?? 

I have just updated to Lightroom 15.4.1, since up dating when I open the masking option I go to people and I get a message no people found, even though the image is a portrait. This now occurs on every portrait I use the masking option.

I’m editing a folder that has 240 photos. They are slides from about 40 years ago that I digitized by taking photos of using Valoi easy35. I hadn’t realized how much dust was on them so I’ve been using the Remove tool with Use generative AI and Detect Objects selected. Because it takes a long time to run, some photos taking an hour or so, I’ve been working on it over a couple of weeks or so. Several times I’ve exited Lightroom and backed up the catalog. After I finally got through the slides I went back to the start to see if I’ve missed any. There are a number of ones that I specifically remember fixing certain blemishes, but were there when I went back a second time.
