Lightroom Classic

In the Send Book to Blurb function first the pages are rendered. Thereafter the upload takes place, during that second part the upload is very often stopped with this pop-up:Error appearing many timesThe pop-up shows very often, like dozens of time (100+ page book, 300+ images). The interval between messages does not seem to be fixed.This is the behavior of machine network while sending (between the errors):Data sent while continuingUnknown if this is normal…The progress bar does continue to go forward, so progress seems to happen between the errors. However, as too many errors are given no full book is uploaded currently.The screenshot is using a cable connection (from machine to router), using WIFI gives the same.This is behavior is observed in the LrC 15.3 and 15.2.1 and previously in early 2025 (LrC version unknown).Machine is Microsoft Surface, current version of Windows, ARM64; further info in attached file.

In Lightroom 15.4.1:Open Image with blue sky Generate a virtual copy Set copy to B&W in Basic panel. Sky retains a blue tint. Adjusting blue tones in B&W mix panel deepens or lightens tint but retains the blue colour. This also happens when using B&W preset such as InfraredNOTE: In further testing, I have only found this behaviour in two images which have been edited in Photoshop and saved at TIFF. 

some of these files date back several years.  How do I best manage them and how do I free up disc space?

Hello, Community.   I'm a photography hobbyist who chases the aurora. Novice-level LRC user. Mostly illiterate when it comes to the details of monitors/sRGB color space.  You guys will be lightyears ahead of me in technical acumen, but I’m hoping you will be able to point me to on-line resources or provide “Dummies” level info to help me understand the image discrepancy I find between the RAW image and what I import into LRC.  Currently working on an older MAC (newer more robust MAC sitting here waiting to be unpacked).   When I started post-processing RAW image from my 2026 aurora trip I immediately noticed a SIGNIFICANT difference between the intensity of the RAW image colors (MAC Preview app) compared to the image imported into LRC Develop module. (both displayed on 5-6 year-old DELL monitor, with same discrepancy seen on husband’s newer DELL monitor)   LRC import images are 1:1.   Is it my monitor settings?  Any information or resources for a novice LRC user to help me understand w

Meine KI preset Maske wird teilweise nicht übernommen. Im Raster Entwickeln ist mein bearbeitetes Bild wie ich es haben möchte - sobald ich in die Bibliothek umschalte ist die Maske weg und somit der Bildlook ganz anders. Auch beim export ist die Maske nicht drauf!

In my Lightroom Classic (15.4.1), the icon for each layer mask located next to the mask name has disappeared. Previously, each mask had an eye icon and I could click on the eye which would turn off the mask visibility and change the eye icon to an eye with a slash through it.  Now there is just a dark gray area with no eye. The only way to turn a mask on or off is to control click on the mask and select hide which is clunky. Is there a hidden setting that will restore the eye icon? Thanks

Lightroom 15.4.1 on Windows.As GPU I have an NVIDIA 4070 with 12GB of VRAM, latest studio driver  6.10.62.In the Graphic tab of the NVIDIA App I can choose to "Optimize" LrC, but if I do then in LrC settings under Performance tab it sets automatically CUSTOM under "Use GPU", option "GPU for export" is disabled and greyed out and it says I have only "Partial graphic acceleration".If I manually force AUTO under "Use GPU" than when i go back to NVIDIA App it says LrC is not optimized, and if I select OPTMIZE again than under LrC Performance it goes back to partial accelleration. Any idea?

Subject: Lightroom Classic creates duplicate NEF files (-2) when importing from Nikon Z8 via USB with dual-card backupProduct: Adobe Lightroom Classic 15.4.1Operating system: macOSCamera: Nikon Z8Issue:When importing photos directly from a Nikon Z8 connected via USB-C, Lightroom Classic creates duplicate NEF files during import.The camera is configured to record identical NEF files simultaneously to both the CFexpress Type B card and the SD card (backup mode).Although Lightroom displays only one import source (the camera), each imported image is copied twice into the destination folder:DSC_1234.NEF DSC_1234-2.NEFThe two files are bit-for-bit identical (same file size in bytes).Important observations:The duplicate files do not exist on either memory card. The camera itself shows only one copy on each card. The “-2” filename appears only after Lightroom imports the files. “Make a Second Copy To” is disabled. No cloud synchronization or third-party sync software is running. Import method

AI Denoise creates rectangular artifacts in smooth sky areas.The artifacts are not limited to the Lightroom preview. They are permanently written into the generated DNG and remain visible in Photoshop and exported JPEG files.The artifacts become much easier to see after increasing the Dehaze slider, but they are already present in the DNG.I reproduced the issue with:- Canon EOS R6 Mark II (CR3)- Canon EOS R5 Mark II (CR3)- iPhone 17 Pro Max (DNG)The issue occurs in both Lightroom Classic and Lightroom Desktop.Disabling GPU acceleration does not change the result.SystemLightroom Classic 15.4.1Camera Raw 18.4Lightroom Desktop 9.4.1macOS Tahoe 26.5.2MacBook Pro 16"Apple M4 Pro48 GB RAMSteps to reproduce1. Open a RAW/DNG with a smooth blue sky.2. Run AI Denoise with default settings.3. Open the generated DNG.4. Increase Dehaze to reveal the artifact more clearly.5. Export as JPEG.6. Open the DNG or JPEG in Photoshop.The rectangular artifacts remain visible.

Environment Adobe Lightroom Classic 15.3 Lightroom SDK Windows 11 Standalone Lua script attached SummaryTransparent PNG images displayed in an overlapping layout do not reveal the underlying image on Windows.Instead, transparent pixels are rendered using the Lightroom dialog background color, resulting in visible rectangular artifacts around the overlay image.The same code behaves correctly on macOS. Steps to Reproduce Create an overlapping view (place = "overlapping"). Add a background image (blue PNG). Add a second image consisting of a 45×45 RGBA PNG containing a single red pixel and otherwise fully transparent pixels. Position the overlay image using a child container (f:row with margins). Display the dialog. A complete standalone reproducer is attached. Expected ResultOnly the red pixel should be visible.The transparent pixels of the overlay image should reveal the underlying blue image. Actual Result on WindowsA visible 45×45 rectangle appears around the red pixel.T

Lightroom Classic Version: 15.4.1OS: macOS 26.4.1 (25E253) Description of Issue: Lightroom Classic sync gets stuck on a single photo. The app does not hang or show an error - it continues running at 180%+ CPU indefinitely, draining laptop battery, until force-quit. Step-by-step Reproduction Instructions:1. Have a photo in the sync queue that triggers a malformed internal lookup (exact trigger unconfirmed - possibly a corrupted preview or malformed XMP metadata)2. Sync begins processing uploads/downloads3. Console log shows: Exception Caught. Name: NSRangeException, Reason: *** -[__NSArrayM objectAtIndex:]: index 18446744073709551615 beyond bounds [0 .. 2]4. That index is NSNotFound (-1) cast to an unsigned 64-bit int, being passed into objectAtIndex: on a 3-element array5. App does not crash or recover - it loops on the same faulty state, spinning CPU Expected Result: Sync should fail gracefully with an identifiable error naming the problem file, or skip the file and continue. Actual R

A while back I wanted to make more space on an external HD and foolishly deleted 5 years worth of travel photos, thinking that I had copies elsewhere. Apparently not 🤔.Since then I’ve relied on previews of those deleted originals, sometimes upscaling them to produce full-screen sized digital memories.I’ve been reluctant to delete old catalogs, thinking that the current catalog references them when displaying previews of the deleted original photos.Those old catalogs now occupy Squillagigs of drive space. Can I safely delete them and still be able to access all previews?

Hello,I’d like to know if it is possible to export in webp format from LrC ? I don’t see this possibility.Is it possible with Photoshop ? Except with save as where I can’t choose size of file.Thanks in advance. 

When I open my pictures in LRc they seem to be OK in the first second but then the views of a number of ‘damaged’ files changes to a corrupted view. Because the view of these files is not ‘corrupted’ in other browsers (Windows, Canon DPP etc.) and only in Adobe views I prsume this is caused by a kind of Bug in the adobe software. Also the fact that it only happens to a number of files that seem to be damaged during the backup some time ago excludes that the reason is my PC/hardware.Making a copy or exporting from windows view or DPP (to jpg or else) does not result in Adobe readible files either.Then repair software (Stellar or else) shows to be unable to recognise the problem.See below an example of:The view in windows The view in LRc in the first second(s) The view in LRc after that The overview in LRc showing it happens to specific files onlyAny idea how to ‘repair’ the files in a way Adobe keeps the undamaged view?  Thanks,Louis

I would like to add some text to my photos after I edit them in lightroom CC. Like, I do bird photography and I want to add the bird name in a corner of the photos. How can this be done? I have attached an example. The only way I have figured out is to add such text as a watermark, but that is not my intent.

I want to sync an new Lightroom Classic catalog to cloud.  I understand from what I’ve seen that anything synced in the cloud on the old catalog will sync to the new one.  Do the collections show in the new catalog as they are named in the cloud or are they named something else?  I have seen  screen shot which shows date taken folders.

Hay Everyone... Has anyone experienced when applying Lens Blur in Adobe Lightroom 13.3 (Windows) cannot execute it?, display "Somethink When Wrong" as per attached screenshot. Please advice how to resolve it. Thank you    

Sometimes, when I’m making a new mask (object selection or brush), the selection will go to the far right in a straight line. I am using an iMac M3 26.5.2 and Lightroom Classic 15.41 at the moment, but this problem has persisted through many LR and OS updates. You can see it in the attached screenshot. I was trying to dodge certain areas on the bronze plaque, and the selection went feral! I have contacted Adobe Help, but they didn’t solve the problem. 

I was editing wedding photos without issue, when suddenly I get this black overlay show up when I did a mask instead of red.   I thought maybe I pressed something that caused the default red to change so I went ahead and did my edits, but then the photo remained with a black muted color on top of it.  I tried choosing a different color overlay color, but with the same result.  HELP PLEASE!! I need to deliver these photos to my client.  Thank you!
