Lightroom Classic

Hello everybody, I want to upload a photobook to Blurb, but while uploading it stopped by half upload saying 'An internal error occurred, ?:0: attempt to perform arithmetic on field 'chunk_size' (a nil value)'. How can I upload my photobook? Thanks for your support. Guenther

I'm photographing a professional doctor for a magazine cover and will teather my Sony A7iv to my Mac Book Pro to LRC. How can I use a PNG, PDF or other format overlay over my image of the doctor so I know where the cover text will located. 

Whenever I try to apply any AI mask to a photo in Lightroom, the app buffers as if it's working on creating the mask, and then the screen turns black. After a couple seconds, the screen comes back but every panel in Lightroom is pure white and I can't perform any actions until I restart the app. Up until a few days ago, the issue only happened occasionally and I was able to live with it. However it now happens every time I use an AI mask, which makes it almost impossible for me to edit photos efficiently.Here's what I've tried so far to fix the issue: Updating GPU drivers, rolling-back GPU drivers, turning off GPU use in Lightroom preferences, editing in a new catalog, installing cloud-based Lightroom (still crashed with same issue), rolling-back Lightroom Classic, changing to lower performance Arc GPU, and clearing Lightroom preferences.Any help would be greatly appreciated!

Problems with Lightroom Classic – ”An error occurred when attempting to change modules”. What to do?I have a huge problem using lightroom. Suddenly I can not change modules. I can sometimes go to the module Web, Book or Map – but not to Develop or Library. Tried calling Adobe Support but after 40 minutes the call got disconnected and I never got called back and the problem is unsolved. The supporter was trying making a second profile on my Mac and probably wanted to install another version on this profile to check if the computer is OK – I’v got no other problems on my brand new Mac. But since the call got disconnected we never ever finished. Setup:Mac Studio Apple M3 UltraSeqoia 15.5RAM 96 GB2 TB of free diskAdobe Cloud installed on main disc I tried uninstalling LR Classic three times. Booting, deleting temp-files, running Disc Doctor etc. EVERY time including repairing disc permissions of course – did not help. I tried twice uninstalling the whole Adobe Cloud pac

Do I not understand something, or is the Lr Catalog Backup completely useless if you don't have the couple of other files in the directory it operates within?  Why aren't those included? I get it that the images are just links. I've been going along, backing up regularly since Lightroom v.1. to an external drive, thinking I was covered. I finally had a HD fail. Bought a new computer and went to recover from my so-called backups, only to discover that each catalog requires three other files not included in its backup file to be able to open and use the backup.. I've wasted three full days. J Kost, in her tutorial on how to move to another machine, explains it all. But if you can't get those other few files, you are screwed. TIP: If you aren't copying the entire folder the catalog operates within, your backups are usesless if you have to move to aniopther machine. TIP: Dont put your catalog in the Onedrive/Pictures as they recommend. That is another nightmare. Getting thos

The LRC mask function do't work. The Radio & linear gradient do not show the boundary lines and center point. It only show the overlay in red. I can not move the masked area around. 

When specified in the import settings (Lightroom Classic/Preferences.../Presets), development presets are incorrectly applied for the Calibration values ​​"Process Version" and "Shadows Tint").( Lightroom Classic V14.5 / Apple M1 Pro Sequoia 15.6.1 / Leica M11 Firmware 2.5.1 ) 

Hello everyone, I'm currently having an issue i can't manage to fix myself. My Lr CC is running on my Windows 10 computer and i have a one for all library in it that holds every images i've taken. Every images with a certain rating goes either in a "saving" dynamic collection or in a "portfolio" dynamic collection based on the stars given. In my case the saving collection has something around 500 images and 100+ for the portfolio one. Then i have a folder that has 2 copies of the dynamic collections but not dynamic to sync them with my cloud in order to find them in Lr on my other devices (iphone/ipad). The thing is that since they are not dynamic at all unlike the 2 that they are meant to stricly copy/paste, whenever i make a change in my ratings or add images, to save me some time, i just clean out the collection completly and select all images in the refering dynamic collection (Ctrl+A) and clic and drag in the normal synced collection. It's important to note that when i do this, i

Oh my goodness. I want to bash my head in. I'm 100 photos away from finishing a wedding, and Lightroom is being so so slow that I can't even stand to work in it right now. I've tried adjusting preferences, upping cache size, disabling parallel previews, turning GPU on and off, resetting all preferences, using only Smart Previews, etc. All it's done is make it even more sluggish and given me more grief with editing. It takes at least 8 seconds to switch between edited images, preview presets, and forever to sync edits...I just want to rip my hair out!! Here's my computer stats:Processor 11th Gen Intel(R) Core(TM) i9-11900K @ 3.50GHz (3.40 GHz)Installed RAM 64.0 GB (63.6 GB usable)System type 64-bit operating system, x64-based processorEdition Windows 11 HomeVersion 24H2Installed on ‎2024-‎12-‎17OS build 26100.4946Experience Windows Feature Experience Pack 1000.26100.197.0 And I'm running Lightroom Classic 14.5.1 that just updated today.

I'm using a powerful Epyc 9575F+RTX5090 workstation, but I find that Lightroom classic's performance is way underwhelming. The example is doing a batch enhance detail for 500 images. This is AI based so it should run under GPU and yes it run under GPU on my old computer and Mac. But I find that in here it runs on CPU, and more disappointingly not fully saturating the CPU. I enabled CCD as virtual NUMA node so task manager will show 8 graphs, and each graph present 8 cores. You can see that only one CCD is used (likely to because of Windows's scheduler trying to bin on one NUMA node aka CCD, which is the reason of enabling virtual NUMA to enhance L3 cache hitrate), and only half is saturated. There's VRAM allocated but GPU not computing. Except for AI functionality speed the overall performance is even worse than my M4 Pro, which is so disappointing. The system information also shows only 6 maximum camera raw threads. Full GPU acceleration is manually enabled and system information prov

Salve, ho davvero bisogno di aiuto sulla mia versione di lightroom classic. Premetto che ogni volta che esco da lightroom faccio sempre il backup, che viene salvato in una cartella nominata: cataloghi ligntroom con data di salvataggio. Lavoro sempre con un unico catalogo su cui ho salvato migliaia di foto rinominate e con vari tag e informazioni inserite. Il problema è che dall'ultima volta che ho salvato con il bakup, riaccendendo il giorno dopo, apro lightroom e è VUOTO dalle fotografie!!! Ma coem è possibile. Non ci posso credere avevo catalogato migliaia di foto. Fatto sempre il backup. Qualcuno mi può aiutare? 

My Lightroom Classic is stuck in full screen. I cannot access the three buttons in the top left to reduce it. I tried the usual; restart but no change. Please advise, Thanks. iMac-macOS Monteray with latest downloads.

If I export original LR only outputs the .xml file not the raw .NEF aswell. Any idea why this is? MacBook Pro Mac OS 14.6.1Adobe Lightroom Classic 14.5.1

Get started with editing your astrophotography images using Lightroom Classic with this easy step-by-step guide.    Editing images is a very personal thing. Some people like a lot of contrast in their images, some like a lot of color and others like to keep things as natural as possible. In this tutorial, I will show you the basic workflow I use to edit my Astrophotography night-time images. You can either use your own image to work on as you follow these simple steps or you can download my sample photo here.   The image I am using for the tutorial was taken on a Nikon APS-C camera mounted on a tripod in portrait orientation. I used an 18-55mm kit lens set at the maximum aperture of f/3.5 for 30 seconds at ISO1600. For this particular image, I left the shutter open slightly too long and as a result, you may see some star trails because the Earth's rotation, but zoomed out the stars look acceptably round. The ideal shutter speed for this scenario, considering that it was

How can I make Lightroom import only RAW and not JPG files? (Some camera's require you to save a JPG next to a RAW to generate the best preview on the camera LCD)

I have recently updated to Lightroom Classic version 15.5 and am having problems opening the app on my M3 Pro MacBook Pro, running MacOS 15.6.  When I first try to start a session it either fails to open and I have to force quit and try again, or takes a very long time to open.  When I do eventually get it to open if I close it down and reopen it does so with no problem. I have tried uninstalling reinstalling the app, but this makes no difference. 

I'm seeingt a bug in LR Classic Print Module's Identity Plate. Now that I've upgraded to Big Sur (11.5.2), I can no longer select the text to edit in a text box. The text shows up when I add it in the Idendity Plate panel window, but then I cannot select it on the image, so I can't move it. Useless this way, since it just shows up over the middle of the photo.  Is anyone else having this problem?    This is the second, and probably more serious of the Big Sur Print Module bugs. The other one is that the image has a color shift and desaturates when viewing in the Print Module.    I'm on an M1 iMac, MacOS 11.5.2, v10.4 LR Classic.

I just installed Lightroom CC on my Windows 11 PC, when I apply Denoise AI, my picture turns blue/purple. Any help please!

Hi everybody, I hope somebody can provide me with the right hint. I would like to view/play my slideshows with a stroke border, black or white, on the edge of each file/photo. However, when the file is cropped, very often the desired border does appear correctly in the preview but does not show at the edge— but rather at a distance from it—when the slideshow is played; the larger the crop, the more distant it shows. Why is this? I've tried with several combinations of Crop & Straighten settings (custom, original, locked/unlocked, etc.) but could not find the correct way out. Can anybody help? Thank you in advance.

In LrC I click on the Mask icon ... when I click on the brush and go to paint everythings seems fine.  When I want to lighten/darken that area there is no eposure (etc) slider ... I know it's somewhere!  An easy fix for sure but I've tried all I know ... Thanks for your help!
