Lightroom Classic

Since updating to the latest Lightroom Classic 15.5 version on a MacBook Pro M1 Max, I have noticed several erratic display and navigation behaviors in the Develop module.First, when viewing photos in Full Screen mode (F key), the zoom setting of the Develop module no longer seems to be retained. For example, if the Develop module is set to 200%, clicking on the image while in Full Screen view unexpectedly changes the view to 33%, instead of retaining the previously selected zoom level.A second, and more significant, issue concerns navigation through the filmstrip using the arrow keys.A short press on an arrow key can now cause several photos to be skipped. Holding the key down launches extremely fast scrolling through the filmstrip, sometimes advancing through several dozen photos. With a longer key press, the scrolling can even continue indefinitely and can only be stopped by clicking directly on the filmstrip.During this scrolling, the main Develop view becomes completely frozen and

I edit a photo, go back to Library grid, open another file for editing, when I enter Develop module loupe view what appears to be a double exposure appears. Problem is resolved by quitting LR and reopening, but returns after a few additional edits. Mac M2 Mini with Graphics Processor ON; Sequoia 15.6.1 

Hi there, I’ve been struggling with a recurring bug in Lightroom Classic (v14.3.1) related to the AI-based Remove tool and the “Update AI Settings” prompt. Here’s what’s happening: I’ll use the Remove tool on an image and allow it to finish processing.I’ll then move to another image and continue editing.When I return to the original image a few minutes later, the removed object has reappeared.A triangle with an exclamation point shows up, prompting me to “Update AI Settings” — even though I’ve already done this previously.This cycle keeps repeating, and edits don’t stick.     What I’ve tried (and confirmed):  I’m running Lightroom Classic v14.3.1 on Windows 11.GPU settings are set to “Auto”, but I also tried manually enabling full GPU acceleration.I’ve restarted Lightroom, reinstalled Lightroom, and even paused cloud syncing.I’ve waited for the AI edit to finish before moving to another image.I cleared the masking cache by deleting the Helpe

Auto updated to LrC 15.5 on my MacBook Pro M3 Max last night. Came home from shooting a concert and the import dialogue would appear to function normally, but after hitting the actual button to import, nothing happened. It went back to the grid view, briefly the import status bar appeared in the top left then just as quickly disappeared. I tried different ways of doing it, enabling full disk access (already was set), copy vs convert to dng, even created a whole new catalog and did a hard reset on my computer. Same issue every time. Decided to downgrade to 15.4.1 through the creative cloud as I was able to recently import and edit on that version. Opened Lightroom back up and viola, everything worked just fine. Gonna stick on this version and disable automatic updates until I hear adobe fixes this.

Hello, I have installed LR 6 on new machine. I can't activate it unless deactivated on other machine. So on other machine I did "Sign out". There is a message - "it will deactivate LR on this machine" - I clicked OK. Still can't activate. On my Adobe account there is nothing under Plans and payment->Activated devices. So haw can I use a product on new machine? I know LR 6 is quite old, but still it is something I purchuased and I want to use.

I’m a heavy volume shooter, I see daily that Lightroom Classic will fail on HDR merges. No errors, no crashes, LRC will just hang indefinitely on “Merging HDR….”.  You can use the program normally. The only way to fix it is to terminate LRC, re-open then merge the stacks again. I notice it usually hangs on large volumes, say 30-40 stacks at a time. 

Latest LRC, during a session right click ceases to work as do all keyboard shortcuts. on macOS Tahoe with an M1 Max. This happens hourly. 

After upgrading to Lightroom Classic 15.4.1, I find that the Before image in the Develop module is often blank.  I have undertaken all of the possible troubleshooting steps with no success.Downgrading to 15.3.1 solves the problem in a new catalog but if I then upgrade that new catalog to 15.4.1 the problem returns.Is this a known bug???

I am truly flummoxed! I’m having major issues printing from Lightroom Classic and I’m wondering if it is due to the update to v15.5. It takes about 5 minutes to print one image. In addition, color is completely off now, and it was fine just a few weeks ago. I’m using a Mac, OS Tahoe version 26.6.1 … and that is a recent update as well (so is is double trouble?). I am printing using my Canon Pro-1100. I print on a variety of Red River papers, and use color profiles provided by Red River. Prior to the update things worked quite well. When I print from the Mac Preview app rather than Lightroom the colors are correct and it prints at a normal speed, which is why I’m thinking it might be a Lightroom issue. 

LrC 15.4.1. MacOS 15.6.2  When LrC is opened for a longer period of time the upper tool bar locks up. I can't hide LrC or access any other tools. I've had to force quit LrC a few times.

Applying Quick Select or keystroke ‘B’ to images in the list of “Deleted Photos to Remove” from a Publish service fails to select images. Only by mouse-selecting to activate the “Photo is in Quick Collection” icon will said image be added to the Quick Collection.  Multi-selecting the “Deleted...” photos is often necessary when metadata for many images needs to updated so that they remain published.

GPS Coordinates bug. When CTRL-Click selecting multiple images on Map view, they all inherit the same GPS coordinates. Restoring coordinates requires reading file metadata.

LR 15.2 introduced inconsistent names for the Backspace and Delete keys in the French in-program shortcut help. WindowsLibrary Help:Map Help:“Supprimer” is French for the Delete key. But on Windows, the Backspace key is called “Retour arrière”. MacLibrary HelpMap Help: On Mac, the Delete key is called “Supprimer”. So the two instances of “Arrière” should be replaced by “Supprimer”. 

quando faça a exportação das minhas fotos em Raw no meu Lightroom (Lr), fica aparecendo uma mensagem que não está sendo possível pois não encontra o tamanho original em nuvem, e está assim a algum tempo, e por mais que meu armazenamento não esteja cheio  fica aparecendo assim. vou deixar aqui o print da mensagem, eu utilizo o computador e o Ipad para trabalho nas imagens, e outra erro e que o uso de IA de um aparelho para o outro não se atualiza sozinho e tenho que ficar perdendo tempo atualizando manualmente.

OK. Now I see what happened, so I’ll start over. I’m hoping that someone has an idea for a fix for this.Re: LRC 15.4.1Running painfully slow. A little history: I’ve been a Lightroom user for over 10 years, along the way Lightroom would bog down once in a while, but it always seemed to function good enough, until it became unacceptable. I was due for  a new system so in 2012 I purchased a new XPS8500. Things went well, but the day came where Lightroom slowed to a crawl again.

I am currently running version 15.5 of Lightroom Classic.  I have had an issue over the past few versions where while in the Develop Mode and trying to  enlarge or magnify the image during editing the screen goes black.  I can only get the picture back by selecting the fit to screen option, but I am unable to utilize a zoomed in version of the image for more refined selections or any other type of editing.  Is this a common error or after all these years am I doing something wrong?  Any help would be greatly appreciated, thank you.

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

Summary: Lightroom Classic throws a generic "unknown error" when importing HEVC video files tagged as hvc1, which is the default output format for DJI cameras (tested with DJI Osmo Action 6). The same file remuxed to use the hev1 codec tag imports without issues. No re-encoding is performed — the video bitstream is identical.Steps to reproduce:Record video on a DJI Osmo Action 6 (or likely any DJI camera outputting HEVC). Or use attached input file.

Hi everyone. I am posting in this forum as Lightroom is what I’ve used, and I cannot find a support email address to ask Adobe directly.I subscribe to a 1TB/month cloud storage, as well as to the Creative Cloud monthly applications package. I am cancelling both services as I haven’t used them much in years. However, there are warnings upon cancelling that photos may be lost if I cancel. I’d like to not lose any of my photos, as I may want to pick my editing back up at a later time. Does anyone know the following:If I cancel my services, if I re-subscribe later, will all my photos be there again in my photo library, or would I be starting from scratch with an empty library and need to re-import everything? If the photos would still be there - will any edits I’ve made still show up, or no? Also… my mind boggles with the locations of all of my photos - when I first started they all lived on hard drives nicely organized, but once services started switching to cloud I became very confused w

Hi.Frontline chat support refused to help me. I have an active Photography plan subscription. My 2015 MacBook Pro is limited to macOS 12.7.6 Monterey and Creative Cloud won't let me download older versions. Can a staff member please provide the official direct installer link for Lightroom Classic v13?Thanks.
