Bug Reports

Lightroom was working perfectly this morning.. I come to load in new images and edit some while sitting here.. and as soon as Lightroom opened up - I tried to slide exposure (and other ones to test those...) and the slider immediately jumps one way or another.  I have reset preferences, turned off GPU.. NOTHING is helping.. please help me! 

Lightroom Classic Version: 15.5Operating System: macOS Tahoe 26.6.2 (25G83)Steps to reproduce: Open a primary Lightroom Classic catalog. Go to File > Import from Another Catalog. Select a large secondary catalog (e.g., 16,000+ or 43,000+ images). Start the import process. Expected result: The catalog import should process all images and complete successfully.Actual result: The import process fails midway with a generic "An unknown error occurred" dialog box.Key Pattern Identified: The import process stops at exact, round batch numbers: On a catalog containing 16,623 images, the import halted at exactly 15,000 images. On a catalog containing 43,881 images, the import halted at exactly 25,000 images. Additional Diagnostic Details: Telemetry log right before crash: last_command = "ag.file.import.fromlibrary" RAM usage remains low (under 3 GB / ~8% memory total), ruling out memory saturation. The exact round numbers (15k / 25k) strongly suggest a batch transaction commit fai

I click on my Adobe Lightroom classic icon, and nothing happens.

Lightroom Classic fails to open after update to rev 16

Hallo,   trotz aktueller Version 14.2 funktioniert bei mir in LightroomClassic seit mehreren Tagen das Kartenmodul nicht. Ich bitte um Hilfe bzw. Aufklärung!

After starting LR, clicking the GPS badge of a photo centers the map on the last-displayed location rather than the coordinates of the clicked photo. To reproduce on LR 15.5 / Mac OS 26.4.1: 1. Open the attached catalog. 2. Go to Map view. 3. In the filmstrip, click on the GPS badge of "miami.jpg". Observe the map centers on Miami (correct). 4. Go to Library. 5. Restart LR. 6. Click on the GPS badge of "san francisco.jpg". Observe that the module switches to Map view and the map centers on Miami rather than San Francisco (incorrect). 7. Go to Library. 8. Click on the GPS badge of "san francisco.jpg" and observe the map moves to San Francisco (correct).  

When using the color grading panel the numerical fields for the Hue and Sat input behave erratically. When moving the Hue slider sometimes the last digit disappears. This happens with single Color Wheel interface. So instead if displaying 235 the field displays 23. It shows this behavior with various value: 231 shows 231, but 220 shows 22. You can check this  when displaying all 3 color wheels simultaneously. The hue values in both image is 235.Lightroom classic is showing this behavior since the last update, 15.6 release. This seems like a bug. I have tried resetting everything to the default settings but that doesn't make any difference.When I edit the same photo in Photoshop Camera Raw, Color Grading behaves as expected.

Description of IssueI believe that at times, Lightroom Classic 15.5 produces phantom pins on the map, that is, pins that appear to be locations of photos, but either the count of images is wrong, or the pin itself doesn’t work (when you hover over the pin, nothing happens), or both. I understand that a major malfunction of the Map module was fixed in 15.5, but this seems like a different problem.Lightroom Classic Version Number (Help>System Info…) Lightroom Classic 15.5OS Version NumberWindows 11 25H2 (26200.9168)Camera Model (sometimes necessary)Nikon Z6 IIStep-by-step Reproduction Instructions (in precise terms, please)Step 1: Select a lot of images and display the map (in my case, all photos in New York State).

Hi everyone,I'm having an issue with the latest version of Lightroom CC on a MacBook M5 Pro running macOS Tahoe 26.5.1. (I was experiencing the same problem on 26.5 and decided to update hoping it would fix it, but unfortunately it didn't.)Since this morning, it's been impossible to to use Noise Reduction, even though my internet connection is working perfectly. I've already updated both Lightroom CC and macOS, cleared the cache, and optimized the catalog, but I keep getting this error screen whenever I try to use Noise Reduction.Has anyone experienced the same issue or knows how to fix it? Any help would be greatly appreciated. Thanks! 🙏 

I exported 479 photos to a folder with “Add to This Catalog” selected.  The export proceeded as expected but the operation to add the photos to the catalog was painfully slow.  It was taking 4-10 seconds for each image.  During the time to add the photos to the catalog all other importing operations are frozen.  During the extended add photos operation LrC is consuming about 7-10% of CPU.  The rate at which photos were added to the catalog is much slower than other operations that add photos to the catalog.LrC 15.3Win11 

This has been happening for probably a week or two. I have it by default apply content credentials to every jpg I export - can’t hurt, right?In every single export lately, a random number of them ‘fail to apply’ and hence do not export at all. I have to keep going to the export dialog, click ‘skip’, and it will export a few more and fail to export a random number. Currently I have done this 8 times to a set of 148, and am down to one single file that it just doesn’t seem to want to apply them to ever. I assume this is a bug and I should give up on credentials until this is fixed.  Mac Mini M4 Pro, OS 26.5.2 

Lens corrections don't work with Photo Merge HDRs merged from DNGs. They do work correctly with DNGs not produced by Photo Merge.   Tested with LR 14.3.1 / Mac OS 15.5:   1. Download and open this catalog:  https://www.dropbox.com/scl/fi/vhm0r8s17csaatgs153pw/hdr-dng-lens-profile-bug.zip?rlkey=6i2o4jgomfzpfbj8gm4eizak8&dl=0    It contains raws from five cameras: Canon EOS R6m2, Fujifilm X-T5,  Nikon Z 7_2, ODS OM-1, Sony ILCE-7C. All the raws have Lens Corrections > Enable Profile Corrections checked.   2. Observe that for each camera, there are three stacks containing these stack tops:   - an HDR made from two copies of the original raw, e.g. DSC_0102-HDR.dng.   - an HDR made from full-resolution DNGs exported from two copies  of the raw with the options Image Format: DNG, Lossy Compression, e.g. DSC_0102-full.dng.   - an HDR made from reduced-resolution DNGs exported from two copies of the raw with the options Image F

Hola;Es mi primer post, he estado indagando por la comunidad, y no he acabado de encontrar la solución.Uso LRC en un MacBook Pro y en varias ventanas de ajuste tengo problemas de redimensionar (salen cortadas). Me di cuenta en la de ajustes de mascara (adjunto captura), pero repasando algunas otras secciones como Ojos Rojos, Recorte… también tengo el mismo problema (adjunto capturas)He probado en modo pantalla completa y nada, se queda igual.Alguien sabe como solucionarlo? Es muy molesto no poder trabajar bien.Muchas gracias.  

Bug Report: Existing AI Sky Masks are deleted when applying another Develop Preset containing an AI Sky MaskProduct: Adobe Lightroom ClassicVersion: 15.6Operating System: Windows 101. Description of the problemI have discovered a reproducible issue when creating and applying Develop Presets containing AI-based Sky masks.When I apply a Develop Preset containing an AI Sky mask to an image that already has an AI Sky mask from another preset, the previously existing mask is deleted and replaced by the mask from the newly applied preset.This happens even when both presets were created independently and contain only one selected mask.The problem also occurs with newly created presets. Therefore, it does not appear to be limited to older or corrupted preset files.2. Steps to reproduceOpen an image in Lightroom Classic. Create an AI Sky mask and adjust its settings, for example Exposure, Highlights, Shadows or Whites. Save these settings as Develop Preset A, selecting only Masking. Modify the

The previous behavior was to match a caption or filename that starts with the search string.   For example, searching for filename that "Starts With" "FE" matches both "FeeDemoWall.jpg" and "Big Tree 12 Feet.jpg"   The same behaviour happens searching for captions. Maybe other things too but I only tested these two.

The new Glow effect in Lightroom Classic 16 contains some confusing and inappropriate translations in the Italian interface.In particular, two preset names deserve attention: "Giorni di seguito" – This literally means "consecutive days" in Italian and makes absolutely no sense in the context of a photographic glow effect. It appears to be an incorrect translation of an English term. "Movimento" – This means "Movement". Although not necessarily incorrect, it is rather generic and does not clearly describe the visual effect. Steps to reproduce: Launch Lightroom Classic 16 with the interface language set to Italian. Open the Develop module. Locate the new Glow ("Bagliore") effect. Examine the available effect styles. Expected behavior:The Italian names should accurately describe the corresponding photographic effects, using appropriate photographic terminology.Actual behavior:At least one style, "Giorni di seguito", has a completely unrelated meaning in Italian.Environment: Adobe

Je suis toujours très ennuyé avec les problèmes de synchronisation.D’un coup je me suis retrouvé avec la totalité de mes photos en cours de synchronisation avec de nombreuses erreurs, au point que j’ai supprimé TOUTE les photos de LRcloud.Je tente depuis de reconstituer à partir de LRC en faisant ça année par année, mais il y a beaucoup de “erreur de synchronisation” que je tente de rétablir, mais il en réapparait d’autres.à ce stade il m’en reste 48 en attente, mais je n’arrive pas à savoir lesquelles ni ce que je peux faire pour corriger.par ailleurs, le panneau en haut à gauche m’indique qu’il ya 639 enregistrements de métadonnées. JE NE SAIS PAS CE QUE çA VEUT DIRE ni QUELLES PHOTOS sont concernées, ni si c’est un enregistrement dans le cloud, dans le catalogue sur mon PC ou si c’est dans les fichiers ! img]IL faut m’aider à résoudre ces problèmes, ça ne dure que trop !comment puis-je avoir une synchronisation fiable et performantes ?Merci de votre aide, c’est URGENT !NB j’ai une l

Description:I have noticed a localization/UI minor issue with the new Vectorscope introduced in Lightroom Classic 16.When using Lightroom Classic with the Italian interface, hovering the mouse pointer over the skin tone indicator (the person icon) in the Vectorscope displays the truncated tooltip "incar" instead of the complete Italian word "incarnato".This appears to be a text clipping or insufficient tooltip width issue, possibly because the interface was designed around the shorter English term "Skin".Steps to reproduce: Launch Lightroom Classic 16 with the interface language set to Italian. Open the Develop module. Display the Vectorscope. Hover the mouse pointer over the person icon representing the skin tone reference. Actual behavior:The tooltip displays "incar", cutting off the remaining characters.Expected behavior:The tooltip should display the complete Italian label "Incarnato", without truncation.Environment: Application: Adobe Lightroom Classic 16 Operating system:

 I am reporting a longstanding and reproducible issue in Lightroom Classic for macOS concerning the Print module and the way color management settings are saved in user-created print templates.This problem was already present in previous versions of Lightroom Classic and still persists in version 16.When selecting "Managed by Printer" under Print Job > Color Management > Profile, the setting is immediately lost after updating an existing print template.The Profile field becomes completely blank.Steps to reproduce Open Lightroom Classic 16 on macOS and switch to the Print module.

I open LrC. I pick an image. I open the map tab.  the data in the upper right corner of the map does not coincide with the data.  It's not even close.See the attachment.
