Lightroom Classic

When multiple videos are selected, Edit Capture Time incorrectly shows the message for a single photo selected, rather than a message that indicates the capture times of the other videos will be adjusted by the same amount as the first: When multiple photos and at least one video is selected, the message incorrectly states that videos will not be adjusted: But in these cases, the problem is just with the message being displayed. Clicking Change All correctly adjusts the capture times of the other videos by the same amount as the most-selected photo/video. Tested on LR 15.4.1 / Mac OS 26.4.1.

Lightroom Classic version 15.4Mac OS 26, Version 26.5.1Mac Studio M4 MaxPrior to the latest upgrade to Lightroom Classic I was backing up my catalog to my Synology drive. I now get the unable to write to drive error, check permissions and available space on the drives. I can backup the file locally on my MAC and then copy that over to the Synology drive. So it does not seem as though permissions is the issue. Have 16TB of storage on the Synology and 782 GB free on a 1 TB SSD on the Mac. Only started when after the latest upgrade to Lightroom Classic.

In LRC, I have many hierarchical keyword structures, amongst which are locations, i.e. Country/State/City and in some cases location or street name.  Since version 15.4.1, LRC deletes upper level location keywords (Country and State, or when there's a fourth level then it deletes the city too) after a photo has been synced to the cloud. The keywords still exist in the cloud. I have checked other hierarchical trees and the keywords are all syncing correctly. If I reenter the locations the save metadata to file, the keywords once again disappear.I'm running LRC 15.4.1 on a Windows 11 Pro computer with Admin rights. Lightroom, catalog and photos are all on (separate) local nvme ssds. Plenty of space, plenty of speed.

Sync Settings with Upright Transforms checked doesn’t always check Copy automatically, as was intended by the undocumented change in LR 15.0.  To reproduce on LR 15.3 / Mac OS 26.2 (see the attached screen recording): 1. Save the attached file Upright-Transforms.lrtemplate (created in LR 14) to the Copy Paste Subsets subfolder of the Lightroom settings folder.  Restart LR. 2. Select two photos and do Sync Settings. Click Check None and click Synchronize. 3. Do Sync Settings again, select the subset Upright Transforms, and observe that Crop is checked (correct).  Click Synchronize. 4. Do Sync Settings again.Observe that the subset Upright Transforms is selected (correct) but that Crop is unchecked (incorrect). When you click Synchronize, the Crop is copied, even though it is unchecked.

Then I apply AI denoise, in LR Classic 15.3 it does it in the background which I really like, however once I apply it to let’s say 100 pictures, and start editing the ones that already editable, it is stopping at the last few images. It is toally random where it is stopping but all the AI denoise remains in a stuck position and I can’t edit those photos unless I restart LR Classic. Sometimes these are images that already have some AI denoise on them, I just don’t bother to select the ones that doesn’t have it, so I paste the settings to all. And usually it is stuck it one point of the process.It only goes through the process if I don’t start editing any other photos, just wait for the whole process to finish. Lightroom Classic version 15.3Mac OS Sequoia 15.7.5Maxed out M1 Max MacBook Pro with Apple Studio Display 5K.

The red-x Reject badges persist on thumbnails in the filmstrip even when all the Select and Reject checkboxes in Assisted Culling are unchecked.  To reproduce on LR 15.4.1 / Mac OS 26.4.1: 1. Download and open the attached catalog. 2. In the Assisted Culling panel, uncheck all the checkboxes. Observe that the red-x badges still appear on the filmstrip thumbnails:  I haven’t discovered any way to make them disappear, including by deleting the Helper.lrdata file.

This is core to my workflow, an absolutely necessary feature I use every single time I’m editing photos. In the Develop Module, under let’s say the “Basic” adjustments panel, one should be able to adjust values (such as Exposure, Contrast, Highlights, Shadows, Whites, Blacks, etc.) while hovering the mouse cursor over a section of the photo (in the Loupe View) and see RGB values changing under the histogram.In the latest version, the RGB values are no longer displayed under the histogram while those values are being adjusted. For example, I click the number next to the ‘Highlights’ slider and move my cursor over to a white part of the image. When I press the up arrow on my keyboard to increase the value of that number, the RGB values under the histogram *should* be displayed and also increasing. Instead, they are not displayed at all.I have downgraded to the previous version and the program’s behavior returns to expected. This is a brand new computer, fresh win 11, AMD Ryzen 7 7700X; 3

Recipe:  When the secondary window is in grid view, it doesn’t always respond to the keyboard shortcuts “f”, Escape, or Shift+g.  To reproduce on LR 15.3 / Mac OS 26.4.1, follow these precise steps (see the attached screen recording): 1. In LR, go to Grid view, close the secondary display window if it’s open, and do Window > Screen Mode > Normal 2. Restart LR. 3. Do the menu command Window > Secondary Display > Grid to open the secondary window in Grid view. 4. Select a thumbnail in the secondary window and type “f”. Observe that nothing happens (incorrect). 5. Do the menu command Window > Screen Mode > Full Screen Preview (the command invoked by the shortcut “f”) and observe that the image is displayed in full screen. 6. Type Escape to exit full screen preview and observe nothing happens (incorrect). Typing “g” and Shift+g also have no effect (incorrect).   7. Type Cmd + Tab and then Tab to switch to an app other than LR. LR is now no longer in full screen mode. 8. C

I am so SAD!  I have bought a new Macbook M4 Max However, Lightroom CC lastest version, cant EXPORT slideshows as videos! the progress bar is stopped at nearly 10% position. No matter if I wait several hours it won't move any progress = I Cant export slideshow as Video   I always used this function, for a few years, day by days   I uninstalled the LR and tried reinstalling it, but it still failed. Does anybody have the same issue?I wonder if it is a problem related to M4 chips. Please kindly help and fix please!

System: Mac M1 Air 16gb/512gb OS: Sonoma 14.3.1 LRC Version: 13.1 Release ---------------   Three Issues: 1) I have a preset folder with six custom presets.  When doing multiple exports using the batch export feature, LRC often doesn't launch the same number of processes as there are presets selected.  I select 6 presets and it will only do 4 sometimes, 5 others.  Sometimes it does all 6.  I have to examine the export folder, see which ones it missed, and go back and re-export the ones it didn't do.  Annoying.   Potential Fix:  If LRC can't do all of the processes because of system limitations (I don't know why on a Mac M1 that would be the case), at least inform the user which ones are being done and which are not.  Perhaps a loop to do sets consecutively with proper UI notification would be a good approach.   2) When doing multiple exports, a dialog comes up for each process, "Preparing to export".   "number of processes - 1

I want to just open adobe lightroom but it take me through the creative cloud and then it looks weird and not what it used to be before it got deleted. I want to just open my lightroom but i can’t and it looks the mobile version, i’m on windows 11 PC. I’ve linked an image as to what i have to open to get to lightroom and i don’t want to do that.  

Lightroom Classic v 15.4 backup attempt results in progress reporter showing “Checking catalog integrity → Copying catalog → Compressing catalog backup,” then reports “Lightroom was unable to back up the catalog named “Lr6 Catalog-v15-4”.  Please check your folder permissions, and make sure that you have available space on your backup drive and main catalog’s drive.”Lightroom has full disc access and backup folder is specifically set to “read & write” for all users.  The backup generator writes a folder named for the backup date into the Lightroom “Backups” folder, but that dated folder remains empty.System specs:  iMac Pro (2017) OS Sequoia 15.7.7, with Mac SSD 2 TB with 790 GB available (far more than the size of a catalog).  Chosing a different folder at parent level produces same result.  Restarting Lightroom produces same result.  Restarting iMac and Lightroom produces same result.  Lightroom restarts and functions (for now), but I am unable to back up my catalog. Thanks for a

it says “Adobe Lightroom Classic” is damaged and can’t be opened. The file was downloaded on an unknown date...

Even submitting this report has a problems. The category selection is organized weird as well. The Denoise function in Lightroom classic constantly need to be updated and never actually updates. The image never stays denoised. It just keeps asking the user to update and fails without notification of it. It just prompts you to update the denoise function again.

I import CR3 files in daily directories into my catalog. I process the CR3 files then export them converting them to JPG I then import the JPG files to put back into the daily directory they came from and to keyword them. The counters on all the directories are set to zero after this import. I have to exit and restart Lightroom to get the counters reset to their actual number of files in each folder. If I delete the CR3's as no longer necessary the counter goes negative by the number of photos removed.

I’ve already tried every option to improve or fix the slowness in Lightroom’s Develop module. Nothing worked—nothing at all—except downgrading to an earlier version (but that’s absurd; I pay to have the best).

Suelo trabajar con un ajuste general a todas las fotos y luego repaso una x una en caso de necesitar algo más.El caso es que a veces uso la herramienta quitar (con IA) o bien, algún preset que contiene alguna máscara.El problema ha empezado cuando le he dado a quitar ruido (y no funcionaba) he actualizado lightroom y ha funcionado. Pero a partir de ahí, cada vez que copio una foto que tiene la herramienta quitar o el preset con máscara, se convierte en una odisea, y me sale en el cuadro de ajustes esto: “El procesamiento de IA está en curso para esta foto.La edición no está disponible temporalmente.”Insisto, hace 4 fotos no me pasaba. Y no sé que hacer. Es muy desesperante.
