Lightroom Classic

I am writing a Python program that analyzes my images and gives me not only feedback about the images but editing tips. Currently it will write a new XMP file based on its findings. What is not included in the XMP file are any masking edits. Where are masking edits and their associated data stored, and are they in a place that I can access programmatically?

I just did the update TODAY & THIS IS THE WORST THING I’VE EVER USED. Just adding a basic backgound/subject mask is taking 20 minutes per photo and it doesn’t seem to sync. I’m not even going to start in on Denoise. I am so frustrated as I just updated, have a huge workflow and cannot edit at all. WTH is going on????

I lost my serial number and I don’t know where to download it again on my MacBook Pro.Can someone help me out?  TIA

Description:When working quickly in the Develop module — applying an adjustment, navigating to the next photo with arrow keys, then immediately applying another adjustment — the second adjustment is visually applied for a fraction of a second, then automatically reverted. Both the image and the slider value return to their prior state. This is not a display/refresh glitch — the slider value itself rolls back, indicating the catalog write is being overwritten.Steps to Reproduce:Open Develop module, select any photo. Apply an adjustment (e.g., Exposure +1.0). Press the Right Arrow key to move to the next photo. Immediately (within ~0.3–0.5s) apply another adjustment (e.g., Exposure +1.0) via slider or keyboard shortcut. Observe: the adjustment briefly appears, then both the image and the slider revert to the original (unedited) state.Expected Result:The adjustment applied in step 4 should persist, as it does when waiting ~1 second after switching photos before adjusting.Actual Result:The

Lightroom Classic 15.4.1 Duplicate Detection appears to ignore duplicate photos stored on an exFAT external drive.Configuration:Windows 11 External NVMe SSD connected via Thunderbolt Drive F: formatted as exFAT Lightroom catalog functions normally Photos open, edit, and save correctly on the external driveDiagnostics performed:fsutil fsinfo volumeinfo F: reports: File System Name: exFAT Is ReadWrite chkdsk F: Completed with no file system errors. Lightroom has full access to edit and save files on the drive.Issue:The new Duplicate Detection feature reports "No Duplicates Found" even though duplicate images are known to exist on the external drive.Because the drive is confirmed to be mounted read/write and Lightroom can edit the files normally, this does not appear to be a Windows permissions issue.Could you please confirm whether Duplicate Detection in Lightroom Classic 15.4.1 fully supports image libraries stored on exFAT volumes, or whether this is a known issue requiring NTFS?Than

I need to do this since I have a project catalog I work in occasionally that needs to stay in sync with another computer that only works up to ver 14.0.1. ChatGPT says it should ask if I want to keep an old version when updating but it did not.  Adobe support says that's right no option is given and it will always remove an older version. My idea is to change the CC program file location, then re-install the old version I want, then change the location back.  Is that going to work or will Adobe still find a way to disable my current updated version?  Adobe support says they don't know if that will work. Windows 11.  

Title: Restore direct Flag and Color Label assignment in the Develop module toolbarFor many years, Lightroom Classic allowed photographers to assign flags and color labels while working in the Develop module. This made perfect sense in a real-world editing workflow.A typical workflow is: Cull and make an initial selection in the Library module. Edit the selected images in the Develop module. After finishing the edit, immediately decide whether the image should be promoted (for example, from Yellow to Green) or receive a Pick flag. Today, the toolbar icons in the Develop module act as filmstrip filters instead of assigning flags or color labels. Because the icons look almost identical to the original controls, it is easy to activate a filter by mistake. In many cases the current photo disappears from the filmstrip because it no longer matches the selected filter.Filtering the filmstrip while editing is rarely part of an efficient workflow, whereas assigning flags and color labels im

it just spins and wont load 

This happens on every photo. I don't remember this from previous versions of Lightroom Classic. 

I am using an Nvidia 4080 on Win11 pro. All drivers and software up to date. I have no idea why Lightroom sees it as windows 10 business. It's windows 11 pro. Regardless, the card obviously blows the system requirements out of the water. Any idea why I can't use this new, 1200$ card for full acceleration? 

(This post isn’t really a “Question” but I felt it made sense to put it under “Questions”)LrC 15.4.1I realize that a chain link fence is not a "reflection", but I got a little crazy and tried Reflection Removal on this photo of a Black Howler Monkey at the zoo. First, the image before Reflection Removal.  Next the image after reflection removal. I think you will agree that this has improved the image. 

When updating metadata fields for a multiple selection in the grid view, only the current photo field updates.It used to update the metadata field for all selected photos.I use this lost feature to update metadata fields such as sub location, caption etc for a couple of hundred photos at a time.I am now having to enter the data per photo which becomes a huge task.

Print module preview randomly turns blank. Sometimes the image appears briefly before disappearing. Epson ET-8550. Reset preferences, disabled GPU, restarted Mac, issue persists. Apple Photos and Epson Print Layout work.

Lightroom Classic 15.0.1, Windows 25H2 26200.7171, Nvidia GeForce RTX 3060 (32.0.15.7602)   I took a photo of a bunch of fish swimming around behind a glass window. I wanted to use both reflection removal and AI Denoise. According to this page, I perform the AI Denoise first.   Here is the photo I used: https://www.dropbox.com/scl/fi/2zqjndbvb4i2mcwqqrgku/PMC_3135.NEF?rlkey=gq1w1mwdiu86oab9avto3wj9i&st=bi4tyj72&dl=0   Here is a screen capture of the unedited version of this photo, you can see reflections as well as noise       Here are the steps I followed:   1. AI Denoise, slider at 50, works as expected, noise is reduced.  2. Distraction Removal: Reflection, slider at 100. Reflection is not removed. Here is a screen capture after both steps, the noise reduction remains effective, but the reflection is not removed.     Also, please note that if I perform the steps in the opposite order (Remove Reflections first, the reflections are removed) but when I then add on the AI Deno

Currently I use the gauss tools from Photoshop to blur faces. Is there something within Lightroom I can use for this? There is this new feature for getting parts of the image out of focus but I could not find a quick way to use it for my task. Thanks!

Hardware & Storage Environment Workstations: MacBook Pro Max (M1, macOS) & Windows 11 Pro Desktop NAS Model: Synology DS920+ DSM Version: DSM 7.3.2-86009 Update 3 Lightroom Version: Lightroom Classic v15.4 / v15.4.1 (Currently parked back on v15.3.1 for data safety) The Workflow & The Breaking Point My core catalog runs locally on a high-speed internal SSD. All original RAW files, heavy Linear DNGs (HDR/Panos), and asset folders live on an SMB-mounted network share mapped via a Synology Drive Team Folder. The moment I updated to Lightroom Classic v15.4 / v15.4.1, heavy transactional network writes—specifically bulk metadata flushes (Cmd+S / Ctrl+S) and file saving operations—began dropping out. This resulted in truncated file sizes, corrupted DNG headers ("file appears unsupported or damaged"), and failed catalog backups directly to network paths. Crucial Note: Completely rolling back to Lightroom Classic v15.3.1 and restoring a catalog backup completely resolves th

My lightroom has been crashing constantly all day since the new update loaded.  I can’t import and if I open an existing catalog I might get to edit a photo before it crashes, but usually not.

I've been using Lightroom Classic to share albums for years using the Share & Invite feature, and this is the first time I've run into this issue.My workflow:Create a shared album. Enable Allow Downloads. Send the shared link to desired party.Recently, I’ve been told that the downloaded JPGs are much larger than expected. I confirmed the same thing myself. When downloading a single photo from the shared album, I can choose between a full-size JPG or a smaller version. However, when downloading the entire album, there is no size option, and it appears to download only the larger JPGs (my last album averaged about 8 MB per photo, some 10-20 MB).I don't remember this being the case in the past. Has Adobe changed how shared album downloads work, or is there a setting I'm overlooking that allows entire album downloads to use smaller JPGs instead of full-size files? My goal is share reasonably compressed JPGs without having to export and upload a separate gallery.

For the second time in a month, LrC when opening says it can’t find the catalogue. Today that happened and I had just used the catalogue yesterday. Today I am trying to use the most recent back up. Last month when it happened, I had to reconnect all my images. This was time consuming. Am I doing something wrong or different. Have not had these problems in the six or so years using the app. 

I have just got an ASUS ProArt 279CRV monitor and 8GB Graphics card but I cannot get Lightroom Classic to develop HDR.  I have ticked the HDR boxes in Preferences presets and performance.  I have uninstalled Lightroom Classic and reinstalled but still no joy.  Any ideas?

I’ve been using 15.4.1 for the past 10 days now and thought I’d share some experiences and issues I’ve found with the latest version;The new subject selection tool in masks is superb! I rarely need to make further adjustments after using it now. I’ve not noticed any change in speed over 15.3 either way and I use a fast W11 PC with 64GB of RAM and multiple SSD’s. My catalog contains circa 15,000 images which are stored on a NAS with the catalog on an internal dedicated SSD. Every time I start LRC since the upgrade, the NAS is running flat out for the first 5 minutes after which it calms down, why? Initially I assumed it was a catalog upgrade but considering I use it every day surely thats been completed by now? Duplicate image detection and catalog sort functions are both turned off in the preferences panel as I have no use for them. I’ve included this comment to try and help isolate the issue in point 3 above. With a slider active, you lose the RGB or LAB read outs below the histogram
