Lightroom Classic

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.

Hello so basically i was editing photos and exported and it when it was done it crashed, i opened it again and it keeps crashing after a few minutes i tried Doing these things -updating drivers-updating windows-reinstall-fresh reinstall-optimized catalog -reset preferences -deleted the lightroom document but none of them still works

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!

When importing photos, Lightroom Classic sees to card, but only pictures on one of them. Then copy the pictures ad try to sync the catalog. Same problem. LR read raw cr3 from canon R5, but not dng files from DJI Mavic2 pro!What to do?

When importing images (I shoot Nikon D800 and D850 with Nikon lenses), lightroom will not identify the lens correctly.  The import shows up as a generic lens:import will be 24.0-120.0 mm f/40 Correct is:Nikon AF-S Nikkor 24-120mm f/4G ED VRThere are a small amount of images that have the correct information in the catalog.  If I look at the EXIF data from a sample of two files, one that is correct and one with the generic name, both have the correct information.  HOWEVER, comparing the xmp files is not.  The DSC_9863.xmp file is the one that works and the DSC_9729.xmp is the one that is the generic name. This has been a pain in my backside for a LONG time and I hope someone has some suggestions. 

When importing Leica M11 DNG files using Adobe Default (as shown in the Preferences / Presets -- Global setting) Adobe Standard is applied as the Profile instead of Adobe Color.  When I create and specify a Preset which specifically uses Adobe Color as the Profile, Adobe Standard is still applied.  If I specify to use Camera Setting, then the embedded M11 profile is correctly applied.  As a work-around,  I can indeed force the Adobe Color profile to be applied if I specify it as the Apply During Import - Development Setting (right-hand panel when importing) and select under the Defaults presets - Adobe Color + Lens or similar. [Moved to Color Management by moderator authority]

Hey there, currently I'm trying to improve my understanding of the RAW development pipeline in lightroom and Camera raw. I am interested in the order of adjustments that are made to an image if I adjust the sliders. Not in the recommended order that people suggest for their workflow to be efficient, but in the order they are implemented in lightroom by adobes software engineers. In Adobes dng format documentation for developers I found that white balance is applied first to an image before it comes to exposure, contrast and so on. For all other adjustments the order is not given. Contrast can be adjusted using the contrast slider and also using the luminosity tab in the tone curve. Since these adjustments are not linear it makes a difference in which order they are applied. I can emulate this process in photoshop if I apply two adjustment layers to a photo, 'Brightness/Contrast' and 'Curves'. If I switch their position the outcome will differ in general. So also in light

When an image is leveled, the crop tool's boundaries are restricted to the rotated canvas to avoid empty corners. However, if I try to expand the crop rectangle toward an area where there is still room, it gets blocked by the opposite edge that has hit the canvas limit. It would be a great improvement if the crop rectangle could automatically shift or slide along the boundary so it can be expanded into the available space, utilizing all available pixels without needing to manually reposition the corner or center handles.

hola, el LR en el dia de hoy no funciona? no puedo editar ninguna foto. cuando se solucionara el problema? la actualizacion se hizo hace 16 dias

I got the 20GB subscription. Since a long time I get warnings about it being full. I have tried everything suggested on your site. Including looking for files on the computer. Have only two photos when I check. My son previously used the other seat when I had the subscription that included Illustration.  Could it be that big files are left from that?

Hello Dears, I have a problem with synch. Last night I tried to synch with 493 photos. Most of development setting was Ok but some of ones missing and/or not correct. For example; linear mask starting point, color adjustment and crop position are different some photos.I tried remove all 492 photos in lightroom and called again. I kept original one which is modified than I tried synch but no change. Issue still there. Is there anybody to face same situation and know solution. I’m using creative cloud desktop version. Thanks in advance for your help.
