Lightroom Classic

Heard a comment from a respectable photographer that LrC could run into a 'won't run' issue with about 5TB of images referenced, irrespective of the size of the .lrcat file itself.  Is this true (I have already exceeded this so worry that I'm on thin ice now)?  Or is the limit on previews?  Or anything else?  Or is this urban legend from someone with a corrupt catalogue?thanks, Bill

intensité du cache quand on selctionne une photo de la grille.   sur les anciens diapositifs il y avait une partie image et une partie cache en plastique ou en carton. sur lightroom quand on selectionne une photo ce  cache est plus sombre quand la photo est sélectionné. etant malvoyant je ne vois pas la difference si une photo est selectionné ou non selectionné. ma question peut-on modfier la couleur ou l'intensité du "cache" selectionné?   merci de vos réponses.

I just started using an identity plates to "sign" my work for shows.   I use custom text.  It works well for landscape orientation -- the text shows up as expected with the baseline near the bottom and reading left-to-right.  When I switch to portrait orientation, the text rotates 90 degrees clockwise, so the baseline is along the left edge and it reads top-to-bottom.   I can find no way to rotate it back to "normal".    Is this a known limitation or am I missing some simple way to have landscape-oriented identity text in a portrait print?

I'm using LR Classic and I'm not seeing the latest features, particularly Remove People and Remove Reflections.  I presume this means I need to update? How do I do that.  I've seen a link in a previous post to an LR Install site, but I'm concerned to do this incase it affects my catalogues etc.  Thanks very much. 

It's 2025.07 and this problem still exists. How hard could it be to fix a slideshow feature in the "leading" photo editing software... ?!@Adobe Team - that's not cool.

I just installed LR CC 12.1 on my desktop running Windows 10.  I noticed it acting strangely (e.g., not zooming when I clicked on a photo, but then randomly zooming later; masks taking like 10 minutes to pop up, etc.)  I finally discovered the pattern - LR is not recognizing many of my left-mouse clicks until I move the cursor out of the LR window.  For example, in Develop, when I left-click on the mask tab, it comes up as expected.  When I click on the mask type - let's say Radial Mask, it doesn't do anything.  It doesn't freeze and I can click other things as well, but the Radial Mask doesn't apply... UNLESS I click Radial Mask, and then move the cursor down to the task bar or to my second monitor.  As soon as the cursor moves out of the LR space, the left-click that immediatly preceded the move applies.  So, my workflow to apply a mask is click Masks tab, click Radial mask type, move cursor to task bar, click on the photo and set the radial mask (w

Hi everybodyThe problem I had repeatedly since the last year: after upgrading LrC to versions started from 13.5 and consequent updating the catalog (which is mandatory!) I get a new catalog which contains NO edits history at all! And the size of the new catalog is 4 times smaller (4 Gb instead of 16,25 Gb).Last year I just reverted to version 13.0.2, and waited since then for newer versions . Today I've tried to install version 14.4 – the result was unfortunately the same as earlier. All edits history (years of work) is lost. My previous catalog saved, but now I even can't see the option to revert Lr version back to 13.0...Does anybody know what might be wrong? Should I have more space on my HD? Should I save my current catalog as a different file? Maybe this is a known bug but then why it lasts so long? I run LrC on a MacOS Sequoia 15.5Thanks in advance for any help or hints. 

I have the 1TB photography plan.  I have been using Lightroom Classic for over 10 years now.  I want to move to Lightroom.I migrated my files to Lightroom and it's being saved on Adobe's cloud storage.  I want to free up my local storage now.  Do I still need to keep my photos locally?  Can I delete my photos now? Does Lightroom (non-classic) need to save photos locally as well? In case this is the wrong community forum, I will post on Lightroom (non-classic) as well. 

Hello,A small mystery here, hoping someone can advise or help 🙂Why will LrC AI Denoise (aka Enhance afaik) process some RAW files but not others, from the same (now quite old) Canon 400D 10MP Camera? Even if I 'reset' the DNG file to remove all changes.Thanks!Andrew

Does Adobe Lightroom have an SDK or a set of APIs that will let me do something like this:// fetch a photo image file from local hard drive or network Image img_original = Image.FromFile("C:\Event123\original\DSC_1337.jpg"); // Use Lightroom's ToneControl.Auto on the ORIGINAL image to create a NEW image Image img_new = LightroomUtilities.ToneControl.Auto(img_original); // take that NEW image and perform Lightroom's WhiteBalance.Auto on it img_new = LightroomUtilities.WhiteBalance.Auto(img_new); // save the NEW image to a local folder img_new.Save("C:\Event123\corrected\DSC_1337.jpg"); I've researched Lightroom's APIs and Firefly APIs several times for the past several months.  And I do not thing this is possible. Here's the context... I photograph events where I may shoot 1000s (or tens of 1000s) of photos.  Then after the event, I load the photos into Lightroom and run Tone Control > Auto on all of them.  And often White Balance > Auto as well.&n

Hi,Does anybody know if there is a custom filter setting to search for all images with a metadata error warning.My catalog seems determined to annoy me on multiple levels.The latest issue is it's decision to begin to create a warning on my images "There was an unknown error while writing metadata to this photo" Retry?This has happened before and I resolved it by selecting every image in my library and clicking the option to "retry metadata export", which seems to mysteriously solve the issue.This took a long time and I was very worried that some kind of keywording would be lost during the update.Keywording is my main way to locate images within the catalog.I don't understand the export option, why am I exporting my metadata, where am I exporting this metadata to?Anyway, I'd like to be able to use some kind of a searchable field or filter setting to select all the effected images, that way I can update all the latest images to suffer and move on.Until next time.Thanks  

My computer is a desktop with an Intel i9 13900k, 64GB DDR5, GTX 1080 8GB. So fairly modern, except for the GPU. I don't want to upgrade the GPU because I have no use for a more modern GPU, I don't play games on this machine.   I recently upgraded to an OLED, 4K, HDR Monitor: ASUS ROG Swift OLED PG32UCDM. Monitor is connected to my GPU via DisplayPort 1.4. And after upgrading the monitor I had to enable HDR on Windows, otherwise the colors would not look accurate:   -------- Now comes the Lightroom settings:   As we can see, Lightroom is correctly detecting my GPU and is going to use it, but the problem is that if I have GPU acceleration enabled Lightroom gets completely laggy and unusable. I can't do anything on it.   I have tried disabling Windows HDR, and that fixes the issue, but then I get awful colors on the monitor. I have tried disabling GPU acceleration and that improves it a bit, but then it uses the CPU for everything and is also not great (but still mu

Release 14.3.1  In attempting to create a new top level keyword. Results in creation of a sub keyword of an existing keyword. 

LRC has become slow to open since yesterday, and freezes when I try to open the print module. Any ideas?

Moin, schon seit dem vorletzten Update wurde Lightroom immer hakeliger. Aber seit dem aktuellsten Update ist es noch schlimmer geworden. Einzelne Fotos bearbeiten mit zum Beispiel Automatisch geht oftmals nicht auf den ersten Klick. Synchronisation über mehrere Fotos ist sehr langsam. Mehrere Fotos (10) gleichzeitig zuschneiden funktioniert sehr langsam. Die Darstellung in den Miniaturen dauert sehr lange oder funktioniert garnicht. Der Katalog und die Fotos liegen auf 500 GB System ssd. Der Mac hat 24 GB RAM.  Kann das jemand bestätigen?   Hi,Lightroom has been getting increasingly clunky since the second-to-last update. But since the most recent update, it's gotten even worse. Editing individual photos using Auto, for example, often doesn't work on the first click.Synchronizing across multiple photos is very slow.Cropping multiple photos (10) at once is very slow. Displaying the thumbnails takes a very long time or doesn't work at all.&nbs

If I enter lightroom classicdirectly from the app on my mac mini I see the normal lightroom screen.If I am viewing a photo in the mac Photos app and then click on the link to edit in lightroom ,I get the screen layout shown in the attached screen shot. Ive no idea why but how can I fix it?Im running mac Sequoia 15.5 and lightroom classic version 8.4 

Hi, I am running LR classic on a Macbook Pro.  I had hard drive issues and had to migrate my collection to a new drive to try to fix it.  Since then some of my collections in LR Classic will sync to LR mobile and others just won't.   Some have a rendering error message.  

I have tried to import new photos into Lightroom Classic Mac from my iPhone, but the import is very, very, very slow. So slow that I use a work-around. I have 59,000 photos on my iPhone Pro Max 15, which has ample free storage, and connects to my iMac Pro using a cable.  My Lightroom is up to date. My solution was to export the new photos from the Photos app on the iMac into a folder on my computer, then import to Lightroom from this folder. Is there a better method?Are 59,000 photos on the iPhone causing this speed problem? Thanks  

For the past couple of weeks, Lightroom prevents me from switching to other programs, either using the ALT-TAB feature or by clicking on the icon in the taskbar. Lightroom always remains the top-most program, even if I run it as a window, rather than full screen. I have to minimize it in order to look at other programs. LR Classic 14.2 and Windows 11, latest updates. Also latest video driver.

Hi,  I'm using Lightroom Classic 14.4 on a Macbook Pro. I deleted by mistake a subfolder with lots of image settings. I still have the original files, but it took me a very long time to edit all the images. How can I restore the deleted folder with the image settings in LR? I went through several threads here and they all talk about finding the backup folder and taking it from there, but there is not such folder in my laptop, see below. Thanks for any help!

This occurs regardless of the number of photos imported (e.g., 100, 500, or 1000) or the clarity of the images. All faces are correctly detected as face regions during import, but only ~100 receive the correct names, even for individuals who are already tagged and recognized in other photos within the catalog.I have Automatically Detect Faces In All Photos enabled in Catalog Settings > Metadata. However, no matter how long I wait after import (hours or even days), the remaining faces with question marks

Attempting to open my catalog, I get no further than :" Lightroom-Opening Catalog_ND_24_1.zip "which appears centre near top of screen.The same thing happens and exactly the same line appears when I click on any earlier back-up file.I have restarted computer many times now and have uninstalled Adobe Creative Suite and reinstalled it with no change !I recently had an issue with an AMD driver which has been updated to solve computer crashing issue (Windows 10 ). LR Classic intitially opened OK after that update but now will not open at all.Any ideas appreciated.

Hallo,ich benutze die aktuelle Version zum Bearbeiten, 50% Bildschirmhelligkeit mit einem iMac. Als Farbprofil verwende ich das voreingestellt "iMac". Problem ist, dass die Helligkeit der Bilder nach dem Export aus Lightroom (und nach dem imDruck) so wirkt, als wenn ich sie auf der niedrigsten Helligkeitseinstellung des Bildschirms bearbeitet hätte. (Export: JPEG, Volle Größe, Qualität 100%, Alle Metadaten, Farbraum: sRGB) Also alles ist extrem dunkel. Mache ich hier einen komplett offensichtlichen Fehler den ich übersehe (bin relativ neu mit Lightroom)? Ich würde ungern alle Bilder noch einmal bei niedrigster Bildschirmhelligkeit nachbearbeiten... . -.- Danke für die Hilfe!
