Description of Issue:When Auto Upright is applied to a batch of photos, Lightroom Classic does not run the Upright analysis on each photo. The other photos get a transform that looks like it was computed for the active/source photo. Each photo only gets its correct, individually analyzed correction after I open it and click "Update" in the Transform panel. On an interior shoot (kitchen cabinets) with dozens of frames, this means clicking Update on every single photo, which defeats the purpose of syncing. This is NOT the known "uncheck Upright Transforms" issue from the thread "Batch Auto-straightening isn't working" (961997). I followed that accepted answer exactly and synced Upright Mode ONLY, with Upright Transforms unchecked. Same result: every other photo still needs a manual Update. Lightroom Classic Version: 15.6 [202609251514-f839cde9], Camera Raw 18.7 (also reproduced on 15.5.1)OS Version: macOS 26.5.2 (25F84), Apple M3 Max, 48 GB RAMCamera Model: Sony A7R V (ARW raw files) Ste

มีใครใช้ Intel Arc A380 กับ Lightroom Classic บ้างไหม? AI Denoise ใช้เวลานานแค่ไหน?

VueScan can save film scans as DNG files with four channels: R, G, B, plus an infrared (I) channel that is used for dust and scratch removal. Older versions of Camera Raw could not open these files at all. The current versions of Lightroom Classic and Adobe Camera Raw now open them, which I really appreciate.I tested most of the Develop tools on these files: Exposure/tone, Tone Curve, Color Grading, Color Mixer (HSL), and Calibration. All of them work correctly.The one problem is the White Balance eyedropper. When I click a neutral gray area with it, the resulting white balance does not neutralize that area. Instead, the area turns magenta/purple-red. The same thing happens in Adobe Camera Raw [version] inside Photoshop [version], so the problem seems to come from the shared Camera Raw engine rather than from Lightroom Classic alone. Lightroom Classic Version: 15.6, CameraRaw 18.7 [202609251514-f839cde9]OS Version: macOS 26.0.1（25A362）Scanner / Software: Epson GT-X980, VueScan 9, outpu

Add Face Recognition to People masking so that a mask for a certain person can be synchronized with other photos and the mask will only apply to that person in all the photos.As an example: I am editing the group photos from a wedding.  I make a change to the brides dress using a People/clothes mask.  I would like to apply that mask to all the group photos.  I can currently synchronize the mask to the set of group photos, but it will currently apply it to the first person it finds in the group.  I then have to go and “add” the bride(cloths) to the mask then remove the incorrect person mask.ideally I could identify the bride in the first edit then when the mask is synchronized, it would face-detect the bride in each photo and appropriately apply the mask to them. 

I’m currently stuck with macOS Monterey. Is there a way to install older version of Lightroom Classic?

Hi I accidently started face detection and now I cannot stop it I think I must had done some sort of keyboard shortcut when it started I checked in catalog preferences- metadata- and the auto face detection was not ticked I shutdown computer and restarted lightroom but it automatically is detecting faces PEOPLE is showing on the bar under LIBRARY, DEVELOP please help!

Hello Adobe team, I am posting here because I am unable to resolve a persistent Lightroom Classic ↔ Lightroom (cloud) synchronization issue after multiple troubleshooting attempts, and I would appreciate guidance from an engineer or someone who can escalate this if needed. ## Subscription contextI have been an Adobe photography subscriber continuously since approximately 2017, originally through the standalone Lightroom mobile subscription purchased via Google Play. In June 2023, I deliberately migrated to the **Creative Cloud Photography plan with 1 TB** specifically to gain the bidirectional synchronization between Lightroom (cloud) and Lightroom Classic - that capability was the entire reason for the migration, since I wanted to keep editing on a desktop in Classic while having all assets and edits accessible on mobile and on the web. Reliable two-way sync is, for my workflow, the core value of the plan. ## Why I am only now setting up the full Classic ↔ Cloud bridgeI want to addres

I exclusively use the Library text filter with comma delimited lists of filenames. Why does this field consistently default to “contains all” instead of “contains?” “Contains all” is not even the first option in the drop down. Is there a way to make “contains” the default?

If you have a catalog with family photos spanning generations there is a real risk of you having more than one person with the same name. And unless one creates an endless amount of Parent > Child hierarchies the risk of ending up with two or more people inside the same Child drawer of the hierarchy with the same name is high. So far the only way I have found as a workaround is to give them numbers. For example John Smith #1 and John Smith #2. My suggestion is that when you place a keyword in the People category it is assigned a unique ID number, which allows you to create more than one identical People keyword inside the same hierarchy drawer as they will have different ID numbers. You’d also need a couple of more fields in the system to associate to the names, like the synonyms field already there. Maybe a small text field where one could write things like “Born 1949”?

Hi,  Can´t acces a download link for v12.x for LrC anywhere, I run Big Sur so I need that version.  Has it been cancelled? Best, Martin

It works fine for a few days and then won’t open.  Task Manager says it is running but I see nothing.  What gives?I should mention my catalog is huge … don’t know if that has anything to do with it.

Hi,I am looking to upgrade my Windows PC and was hoping someone may be able to tell me how long it should take to Denoise one 45MB photo in Lightroom using the recommended spec'ed PC for Lightroom Classic? My current PC takes about 14 minutes per photo.

Hello Adobe Community,I am exploring the development of a local desktop photo-editing tool that integrates with Lightroom Classic through its official SDK.Before proceeding, I would like clarification regarding Section 6.16 of the Adobe Developer Terms of Use (June 18, 2024), concerning machine learning and artificial intelligence.The proposed workflow includes: Analyzing RAW photographs owned by the user, using locally developed image-processing algorithms. Calculating exposure, white balance, contrast, and color adjustments. Applying those adjustments through the official Lightroom Classic SDK while preserving non-destructive editing. Potentially training a local AI model to learn editing preferences from Lightroom Develop settings and edited photographs, but only if explicitly permitted by Adobe. My questions are: Is it permitted to use independently developed algorithms to calculate photo adjustments and apply them through Lightroom Classic SDK APIs? Does Section 6.16 prohi

So since 2 days ago, every time I try to apply a preset I get this pop-up saying “Some AI models are downloading. Please try again later.” that stays stuck at 0% and doesn't move.I saw one of the possible fixes may be to log out and back in, but when trying to log out I also get an error, the one in the attached picture.I've tried restarting my computer and router, changing firewall/antivirus settings, running as administrator, reinstalling LrC, and none work.It seems like all of a sudden LrC can’t recognize that I am connected to the internet.Does anyone have any other potential fixes? Thank you. 

Description of Issue: I recently upgraded Lightroom classic to version 15.6. Before that it used to take around 10 seconds to run Denoise in one of my files (photos from Nikon Z8). Now it takes around 25 to 30 seconds. This time does not change if I set the “Use Graphics Processor” preferences to off or custom. It seems that the software is always using the CPU instead of GPU. In spite of this behaviour, the application is recognising my processor (Apple M1 Ultra) and it says that it supports full acceleration.Lightroom Classic Version 15.6OS version 26.7.1Camera model: Nikon Z8Hardware: Mac Studio M1 Ultra, 128 GB

AI Denoise consistently fails to complete on my machine. This is 100% reproducible and has persisted across multiple Lightroom Classic and Intel driver versions, including the current pairing of both.System:Lightroom Classic 15.4.1 [202606201310-b9f148a4], Camera Raw 18.4 Windows 11 Home 26200 Intel Core Ultra laptop, 16 logical cores, 32 GB RAM Intel Arc 140T integrated GPU (16 GB shared), driver 32.0.101.8860 WHQL (current, verified in Device Manager) Files: Fujifilm RAF (X-Trans)Symptom:Click Denoise. The background progress indicator (top-left) immediately shows roughly 10% progress, then never advances — waited well over an hour. The photo becomes locked: "AI processing is in progress for this photo. Editing is temporarily unavailable." Task Manager shows the Arc 140T near 100% compute utilisation for the entire time, so the GPU is actively executing something — it just never finishes. Exiting Lightroom during this state leaves orphaned Lightroom processes that must be killed in T

Hi all,I'm using a four-year-old laptop with an 11th-generation Intel CPU for LRC. The AI-driven features, especially noise cancellation, are incredibly slow. I've decided to buy a new, future-proof laptop, but what CPU/GPU should I get? LRC used to not use a GPU in the past, but now it does for AI-powered features. But some of the latest processors, like the Intel Core Ultra 7 258V, support AI without graphics acceleration.I'm curious what are your experiences which is the best solution? Does anyone uses Intel Core Ultra 7 258V with LRC? Could it be enough for AI supported functions? Or go for a good CPU/GPU like the Asus ProArt 16 which has AMD AI 9 HX 370 + RTX5080? Or should I switch to MacBook Pro which is also could be case. Regards,Jani

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. 

It seems to happen when syncing images to the Cloud, but LrC is stripping the paragraph breaks/returns from the caption field in the metadata of images, creating one large block of text impossible to read. When you Read Metadata from File, the breaks are restored and the caption field looks normal again. Then a few moments later the breaks disappear, I think when the image syncs to the Cloud. The Caption field text was created in Photoshop not in LrC. But Classic reads the data, then ruins it. This behaviour started about 2 months ago.
