Lightroom Classic

I used to use HDR editing all the time and one day about 2 weeks ago it stopped working and says it's not compatible with my Pixel 10 Pro XL. I've tried all the troubleshooting steps. 

Ever since LRC 15.2 I’m no longer able to create AI masks on any image. It starts to createthe mask then exists the mask creation with out creating the mask.  I’m on the latest build of LrC and have updated the drivers for my Nvidia 5020 GPU. I do not get the same behavior on Mobile. 

Dear I would like to use a smart collection that depends on the keyword and I am having many problems:if the keyword has many words for instance “blue birds” and there is also a keyword “birds” if I look for photos with just “birds” it also shows photos of “blue birds” if I work  with keyword trees, for instance I do have “birds” and inside two other keywords “small” and “big”. Some photos do only have “birds” and other do only have “small” or “big”. If I ask the filter to show “birds” it also shows those photos with “small” or “big” keyword and that do not have the “birds”. another problem with the keyword trees: supose that I add another keyword “dogs” and inside it I have “small” and “big” keywords. I did not find the the solution to make the smart collection show photos with the specific  “big” keyword inside “dogs”. I have tried “dogs > big”, “dogs / big” but didn’t work I have been trying to use a synonim for each keyword with a code without spaces and asking to include the co

Hi, I had new 2nd shooter working with me yesterday, his CR3 files don’t show in my Lr Classic. I downloaded normal version of LR and all fine. I worked with CR3 files before and didn’t have this issue. Photos show fine in Photomechanic too. When i open a photo via photo viewer, it says “Locked” though i checked all settings and files are not locked, or read-only. I am lost of what else i can do ? 

I’m curious how other Lightroom Classic users handle the file-management side of their workflow when working with a lot of photos.After culling/editing/exporting, do you still end up doing things manually outside Lightroom — renaming files, moving images between folders, separating selects/exports, preparing files for another tool, etc.?I’d be interested to hear what your workflow looks like, especially the repetitive parts that Lightroom Classic doesn’t completely cover for you.

On my laptop I use Lightroom & Lightroom Classic. I am told that Lightroom Classic can be used on 2 devices. How do I get it on my phone. I downloaded the free Lightroom from the App Store. Is that different to the version I pay for.

i deleted light room classic files and now im trying to export files from aftershoot to lightroom classic and it wont open 

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.

See attached screenshot.

Lightroom Classic 5.7 terminates when trying importing files.Worked well av few hours ago but now when starting the computer and Lightroom it terminates immediately.

When I want to skip through hundreds or thousands of photos in Lightroom Classic (Version 15.0.1) in the film strip I mostly get this very annoying problem: after holding the arrow key to the right or left for a few seconds it doesn't stop anymore to speed through the images though I'm no more holding the arrow key. Sometimes it's going on for "just" a couple of hundred further photos and sometimes even through thousands of photos until the very last photo in the strip. I can't even stop it.This first started three months ago when I updated on a new MacBook. On my old Macbook this never happened in years. Does someone got an Idea to fix this bug?

1-i click normalwell than just do this and no Denoise3-now I can click again but no work ofc 

I’m trying to bring out more luminance in my photos on my MacBook Pro with an XDR display. When I increase Exposure, Lights, or Whites to expand the histogram into the extra HDR stops, the colors end up looking like they came from an acid festival.When I check the exported HDR photo in the Gain Map Demo App, I notice that the gain map contains colors. However, when I look at HDR photos from Instagram or the Radiance+ app on iOS, their gain maps appear monochrome.Why is it like that, and how can I change it? Also, why does adjusting the HDR version of the photo affect the SDR version too? I already have a finalized SDR photo—I just want to add luminance for HDR without altering the SDR image.

In Lightroom Classic, when I use either the Radial or Graduated Filter, there is no handles. I cannot adjust the filter because there is nothing which allows me to move it with. Is this how it should be. It is not like this in Lightroom.

This is the screenshot…  … anyone else get this?

If I have two keywords, say, “Bob” and “Mary” I know how to search for all photos containing BOTH keywords. Is there a way to search for all photos containing one OR the other (or both)?

Create collection in LR not working. I click the button, nothing happens. Even with Smart Collection too.. no error message or anything.  I’ve tried to reset the preferences, I created a duplicate/new catalog. Nothing is working. Also, I can duplicate a collection, but I cannot rename it.. 

Bonjour,Je constate pour la première fois que mon LRC m’affiche “analyse des photos” et que progressivement sur chaque vignette il apparait une croix rouge. Qu’est-ce que ça veut dire ?  

J’ai posé une question il y a plusieurs semaines sur le thème [Lightroom Classic Discussions] Re: problèmes récurrents de synchronisation impossible à diagnostiquer. Je n’arrive pas à la retrouver dans la nouvelle communauté, et les liens contenus dans les notifications ne débouchent sur rien. Je veux reprendre la discussion et qu’on trouve enfin une réponse à mon problème !une personne Anshul_Saini m’avait demandé de lui envoyer par message privé un gros fichier de diagnostic. Il m’en a fait un accusé de réception, depuis plus rien. comment retrouver les messages enoyés et reçus ?Comment peut-on avancer ? je suis las de la complexité du fonctionnement de ce forum.

can’t elaborate any more . It makes no difference if I select brush, objector any other mask, the area selected area is blue and yellow. I have tried to get copilot help, but all to no avail. It seems to be since the last upgrade 15.5.1

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
