Hello, I'm creating photo series for photo booths and I need to stay within Lightroom to manage the flow of automatically captured images. I need a plugin for Lightroom Classic that allows me to automatically apply background transparency and apply an image that I load to the background of a series of images in print mode.

Hi everyone,I had to replace the hard drive on my MacBook Pro, which uses Monterey and cannot be updated.I was using Lightroom Classic v.13, but I can no longer download that version from Creative Cloud because, unlike Photoshop or other software, the menu with the three dots only shows the Available Plug-ins option and no longer allows me to download previous versions. This was possible until recently. What can I do? I can't change computers right now, and I need the software (which I pay for) to work. Thank you.IP 

I cannot create a Mask since LrC v15.2 installed.Steps to reproduce: In Develop module, click on Mask icon, select subject nothing happens.Select object and draw round the subject, the Masks panel briefly appears then disappears but no mask is selected.Repeated the process on other photos with a very clearly defined subject and had the same result.I’ve re-installed v15.1.1 and used select subject on the same photo and it worked perfectly.Windows 11 Pro 25H2 Build 26200.7840 Nvidia GeForce RTX 4080 Super

Dans Photos E je ne retrouve que les photos à partir de 23 04 10. Tout le reste est introuvable.

The sky detection mask stopped working. When I click on “sky” icon, the “detecting sky” message comes up for a split second, but nothing. Also the mask and brush selections work intermittently - I can’t tell when or why.I re-installed lighroom, switched GPU on and off in lighroom settings. Any help?UPDATE: I reset all the preferences (shift + option ) on startup and that seems to have resolved it.

Dear,I would like to know how to obfuscate or protect Lua Lightroom plugins. The SDK manual tells just to compile, but with well known decompilers I can recover the source code without any problem.I have tried Hercules-Obfuscator, and some online obfuscators, but they do corrupt the code. They brake the code in: Changing the names of table’s keys that Lightroom need to know (for instance “LrPluginName” in Info.Lua Changing names of exported functions/variables in one file and then it can not be recognized in another one. If I make a file “helpers”  that returns “{ onefunc(), anotherfunc()}” the obfuscators I tryed change the exported names and can not call them from another file with requiere(‘helper’)  and  helpers.onefunc() Probably other parts I have tried turning on and off hercules options, but failed to be able to run the plugin Is there any way to protect the code?

I have a library of around 200k images held in folders in date order. I like to have standard previews built so that I am not waiting for images to load for a particular folder before inspecting them.  So  when trying to build standard previews for large nyumbers of images, it takes just one flaky image to stop the whole process and trying to find the one image that is preventing preview build, it is highly frustrating.  Why on earth can’t the code be written in such a way, that if it takes too long to build a preview, just mark it as broken and move onto the next?  Or at least telll me which image is causing trouble?Thanks

trying to import edited jpegs from lightroom cloud to lightroom classic, ironically for better export settings. exported from lightroom cloud with ‘original + settings,’ yet when importing to lrC, no metadata seems to have transfered (photo is unedited). am i forced to export as full quality jpg? with a base file in .jpg format, is this equivalent to exporting with ‘original + settings’?thanks

Dear,Is there any way to set and get the color label of a collection from the SDK ?

Seit dem Update auf 15.2 funktioniert die Maskierung von Personen nicht mehr, selbst auf Bildern im Katalog auf denen Personen zuvor erkannt worden sind. Es erscheint stattdessen "Keine Personen gefunden".

Is it possible to options to context menus with lightroom SDK? I can add menu entries in the menu bar, but it would be much satisfiyng if I can right click on a photo/collection and the my menu appears there.

I'm attaching a screenshot of what Spotlight shows under the Apps icon on the task bar.Adobe Creative Cloud installs ten (10) separate "helper apps" under Applications,  It's mess.Could Adobe at lease consider recoding these so they only appear under "Other"?  

My lrcat-lrdata folder is corrupted, online i read to delete it and lightroom would reacreate it but it did not fix the issue. Now if I open the pictures in the develop module i see an uknown error shown but my edits are loaded as the values are shown on the slider but they are greyed out. I contacted support but they told me to remove and reimport the pictures but it’s quite useless as I would lose all my work and all the settings since they are not saved as xmp. I cannot export the xmps now and it says I/O error if i try to do so.

Since the update to LR 15, I am having a frustrating problem with grid view, where tint grid cells with label colors is no longer working for items that were previously tinted. Instead in the upper left corner of each of the image grid windows, it will say “[Color label name]/[number of stars]” in the upper left corner. For example if I had it labeled red with 3 stars it will say “Red/3,” and if it is yellow with one star it will say “Yellow/1.”  The stars do show up with the image, as do the flags, but not the color tint. I can add the tint by selecting the image and tapping the associated color number. For example, I select images  that have Yellow in the upper corner and tap the 7 key and it adds the tint and changes the text to “Yellow_Published” which is a nice idea to include the word “Published” which is what Yellow signifies to me. The screenshot of grid view attached shows what all the images look like now (left) and what happens if I hit the 7 key (right). But I have tens of

There is zero activity on my machine while waiting for Lightroom to open,  When it did open I ran the diagnostics and found this of interest,  it correlates to the wait time,  in the middle it mentions the user id key ?2026-01-29T17:12:31Z: cloud model cache refresh failed: 2000072026-01-29T17:12:33Z: cloud model cache refresh failed: 2000072026-01-29T17:12:36Z: cloud model cache refresh failed: 2000072026-01-29T17:12:39Z: cloud model cache refresh failed: 2000072026-01-29T17:12:42Z: cloud model cache refresh failed: 2000072026-01-29T17:12:45Z: cloud model cache refresh failed: 2000072026-01-29T17:12:48Z: cloud model cache refresh failed: 2000072026-01-29T17:12:51Z: cloud model cache refresh failed: 2000072026-01-29T17:12:54Z: cloud model cache refresh failed: 2000072026-01-29T17:12:58Z: cloud model cache refresh failed: 2000072026-01-29T17:13:01Z: cloud model cache refresh failed: 2000072026-01-29T17:13:04Z: cloud model cache refresh failed: 2000072026-01-29T17:13:07Z: cloud model cac

Nikon Z8 Camera lens Nikon AF Nikkor 24-70mm F/4S is not listed in the supported lens list for Lightroom Classic 15.2 version. In LRc 15.2 in the Develop Module in the Len correction panel the Lens is not showing although we open a Nikon .nef file format. This specific lens was released on 23 August, 2018.

During export I want to rename my exported images to <uuid>.jpg.Is there a smarter way then my code below?exportPath = "D:/Temp"for i, rendition in exportSession:renditions(renditionParams) do -- Wait for the upstream task to finish its work on this photo. local success, pathOrMessage = rendition:waitForRender() if (success == true) then local newFileName = LrPathUtils.child(exportPath, rendition.photo:getRawMetadata("uuid") .. ".jpg") local result, message = LrFileUtils.move(pathOrMessage, newFileName) endend 

Example of the issue: ISO 250 EXPOSURE:+2.00 AI Denoise 50%When running denoise and raising exposure on my X-H2, I notice a pattern of colorful artifacts throughout the darker areas of the image. The above image was a screenshot taken at 300% zoom to visualise it more readily, but it is visible at 100% zoom (and persists after exporting to jpeg). The behavior is present on all photos I have tested. This does not occur when using the DxO demosaic/denoise algorithms, so I do not think it’s an inherent flaw of the photo. Is there a way to fix this? Software: Lightroom Classic version: 15.2 [ 202602111402-ec4112e8 ]License: Creative CloudLanguage setting: enOperating system: Windows 11 - Business EditionVersion: 11.0.26200Application architecture: x64System architecture: x64Logical processor count: 12Processor speed: 4.7GHzSqLite Version: 3.36.0Adobe GSDK Version: 1.4.0.171CPU Utilisation: 2.0%Power Source: Plugged InBuilt-in memory: 31814.8 MBDedicated GPU memory used by Lightroom: 5238.7

My problem is described in an previous,elaborate post (Lightroom Classic automatically restores all changes done on "develop" module) although I am using a Mac M5 OS 15.1.Library module does not automatically read and implement edits made and recorded in history until manual click on history thus I must navigate to Develop module and navigate to left-most panel in history, which is inevitably at the bottom, then scroll up to historyThis is time consuming, frustrating and maddening.Even if the LR tecs can’t fix this problem, which I believe is shared by many judging from the past, perhaps they could add a toggle in library that automatically updates history in the Library module. 

This is the lamest community bulletin board software ever implemented.  Way too hard to just give Adobe a rarely deserved compliment.  Adobe is so lame at all but a few things.

I have a query about being unable to 'Vote' for a post in 'Questions'.In the previous version of the forum we could vote on a discussion (now 'Questions').  Some discussions had many, many votes, showing that a lot of users had the same problem as the initial poster.  The number of votes was an indication that it should probably be investigated by Adobe or could even potentially be a bug.As I understand it, a discussion is not moved to bugs until it can be reproduced by Adobe (see a couple of posts by ​@Rikk Flohr_Photography at the top of the 'All posts' page).  It can take a very long time for Adobe to acknowledge an issue as a bug, so how do we now indicate in 'Questions' that we also have the same problem?  If the answer is to click 'Like', then to my mind this is not really the same as upvoting to indicate that you have the same problem.  It just means that you like the post!  Can the option to ‘Vote’ be reinstated in ‘Questions’?
