Slow at starting up and loading all of its assets

Why is the latest version of Lightroom so incredibly slow even with a 8-core I7- 10700K 32GB memory and RTX 3060 12GB and installed on the NVME my Windows 11 is on?!?!?!?!?! The program is incredibly slow at starting up and loading all of its assets, using things like sky mask is atrotious and the overall experience makes me wanna ip my hairs out of my hair! GLITCHY SOFTWARE! even with all the Catalog and Preference settings recommendations dont make a light bit of difference in performance!

Can't get rid of "Welcome to People View"

Hi,I was entering keywords for my images and suddenly the main panel was filled with "Welcome to People View."  I can't find any way to get rid of it.  Google says to go to Edit > Preferences > General > Privacy Section > deselect Enable Prople View.  But when I go to Preferences > General, there is no Privacy option and I can't find it anywhere else.  I don't want to use People View.  Please help me get rid of this screen and disable it in Preferences.  Thanks.Zaffer

P: Allow Assisted Culling to analyze only selected photosOpen for Voting

Currently, Assisted Culling analyzes all photos on the memory card, which can take a long time. Please add an option in the Assisted Culling window to exclude specific photos or folders from the analysis, so only the selected images are processed. This would significantly reduce analysis time and improve workflow efficiency.

P: Ability to name custom crops and have more than 5Open for Voting

I would like to be able to name custom crops in Lightroom. Saving them as ratios is great but one step further would be the ability to give them a relative name for certain projects or uses.Perhaps also not limit me to 5 custom ratios. Image is not available

Erx: a need to save and organize my crop ratios as presetsOpen for Voting

I use 11 different aspect ratios for my fine art crops and would love the ability to save and organize them as presets for a quicker workflow. Right now, the crop ratio menu feels disorganized because it shows random ratios instead of the ones I actually use.Ratios I use: 4:5 - 5:7 - 3:4 - 1:2 - 2:5 - 1:3 - 1:4 - 9:16 - 3:5 - 1:1 - 2:3

Erx: Assign a name to an aspect ratio in CropOpen for Voting

I often find myself wanting to crop an image for one of several frames I have. Or for different social media uses. But I don't always remember what aspect ratio should be used for this or that frame. Therefore, it would be very useful if it were possible to save cropping presets with a name, just like importing or editing presets.

Lightroom Classic is not transferring Lens Corrections and Transform adjustments to Photoshop

Hi everyone,I’m experiencing a strange issue with Lightroom Classic and Photoshop, and I’ve already ruled out most of the common causes.System:Lightroom Classic 15.4.1 Photoshop 2026 Camera Raw 18.4 macOS 26.5.2 Apple Silicon (M4 Pro)The problem:When I use Photo > Edit In > Adobe Photoshop, the image opens in Photoshop, but all geometric adjustments made in Lightroom are missing.Specifically:Lens Corrections are not applied. Transform/Upright adjustments are not applied. Perspective corrections are lost.However, other Lightroom adjustments (such as exposure, white balance, etc.) appear to transfer correctly.What I’ve already tested:The issue happens with all lenses, not just one. Exporting the image as a TIFF from Lightroom and then opening that TIFF in Photoshop works perfectly. All Lens Corrections and Transform adjustments are preserved. The issue only occurs when using Edit In > Photoshop. I have tried both the latest versions and older versions of Lightroom and Photoshop.

I allowed LRC 15.4.1 to upgrade my catalog, now it shows me previews but cannot find the photographs.

Using a MacBook Pro Sequoia 15.7.7. I tried an ‘Old Lightroom Catalog’ from finder but result is the same.

Help with accessing photos after transfering files to a new hard drive

I was close to running out of space on my hard drive (“X”) so I transferred > 190,000 photos and the Lightroom Classic to a new hard drive, which has a different letter (“Z”). I did this using Windows Explorer instead of within Lightroom as I understood it was quicker and more reliable to use this approach. I then disconnected the old hard drive (“X”) to ensure all access to Lightroom was via the new hard drive. I am able to open the catalog in Lightroom but the folder structure does not appear. The Photos folder is on the hard drive but I can’t get the software to recognize it. It is my understanding that I shoud not use “synchronize” since I would lose all past edits. Is that correct? I also read about using the “Find the Folder” function but I don’t see that option anywhere. How can I get Lightroom Classic to recognize the photos that are stored on the hard drive and hopefully not lose the edits that are already incorporated in the catalog?

I love PS denoise for my bird shots but for some reason it no longer works. I get an "unknown error" message.

I have been using Photoshop Ai denoise since last year when it first appeared in a regular update sometime in late? 2025. I since have used it to improve hundreds of old raw files going back several years and last I used succesfully on some high iso bird shots in Feb this year. I tried to fix some noisy shots yesterday July 6, 2026 it gave me the “unknown error” message. I went back to several raw files that I had previously created enhanced .dng files but I always got the same error message. Something has changed in the four months since Feb.I use a 27” Retina 5K iMac, late 2015, running OS Monterey Version 12.7.6.32 GB memory, AMD Radeon R9 M395X 4 GB. I have purged the cache, and the scratch discs have plenty of space left.

2-3 mins while I wait for an image to load.

So I am going through trying to edit and my Lightroom is lagging so so badly. Like it's been between 2-3 mins while I wait for an image to load. As well as I am trying to select images it will give me grey squares in the reel and waiting for another 5 mins for things to load. Anyone else had these issues?

I use two smugmug plugins to separate watermarks and image size. After last update, one was disabled. I can see the galleries but cant reconnect it to lightroom.

I use multiple plugins for lightroom including smugmug, adobe stock and wix. After the last upgrade of lr, and windows 11, I have lost connections to these plugins. The folders are still there and I can view the images in lr but get a “null error” and cant access them to add or change content.The worst is smugmug where i use two plugins for two different watermarks. One for my normal business watermark, one for person images. This avoids having to edit the gallery settings each time I load. I still see one enabled but not the other. The images in the disabled gallery cannot be copied to the other gallery so I have lost access to 5k images. Is there anyway to reconnect or resync the disables galleries?

I wish Hasselblad devices could work in connected mode in Lightroom Classic like Capture One. Is it possible?

Good morning,I use Nikon and Hasselblad cameras. I saw Capture One's announcement about their latest update and support for Hasselblad devices, as well as the connected mode that will arrive a little later. I must say that I am a little shaken and thinking. Can we hope that Lightroom classic will do the same? I may be wrong, but I feel like LRC is really more focused on consumer photographers and influencers, while Capture One is more aimed at professionals and serious amateurs.

I'm unable to open any Adobe 2026 applications or products on my Windows system.

I've been having an issue for quite a while where I can't use any Adobe 2026 applications on my Windows PC after updating.I've tested Photoshop, Illustrator, Premiere Pro, and After Effects, and they all behave the same way:The application launches and starts loading. After a few seconds, a pop-up appears with Error 224. The application then closes and cannot be used.The only workaround I've found is to roll back to the previous versions, which work normally.Here are the versions I'm currently using:Premiere Pro: v25.6.6 After Effects: v25.6.6 Photoshop: 26.0.0 Illustrator: 29.0 (64-bit)My hardware:GPU: NVIDIA GeForce RTX 4090 I've already updated both the latest NVIDIA Studio Driver and my GPU drivers, so everything is fully up to date.Could you please let me know how I can resolve this issue? I've been dealing with it for a long time and haven't been able to find a solution.

P: SDK: Restore ability of Copy Settings plugin to work around longstanding LR bugsOpen for Voting

LR 15.4 changed the representation of brush masks returned by photo:getDevelopSettings(), making it impossible for the Copy Settings plugin to provide a workaround for the numerous, longstanding bugs copying local adjustments between photos with different orientations. A relatively simple change to the implementations of SDK methods photo:getDevelopSettings() and photo:applyDevelopSettings() would restore the ability of Copy Settings to copy local adjustments correctly, lessening the need for Adobe to fix all the bugs in Copy/Sync Settings. Details Prior to LR 15.4, the strokes of a brush mask were represented by a "Dabs" array of points: Dabs = { [1] = "d 0.038236 0.022757", [2] = "d 0.037902 0.025261", [3] = "d 0.037802 0.027775", [4] = "d 0.037799 0.030289", [5] = "d 0.037798 0.032803", When copying a brush mask, the Copy Settings plugin would translate these points to match the orientation of the target photo, so that the mask would appear in the correct positi

Bug Reports

I start with an edited version (lightroom adjustments only) of a photo in lightroom. I make a copy of it and then click reset on the new copy. This copy is essentially no modifications at this point. I then edit that copy in photoshop. When I am done editing in PS, I save it. I then open that PS-modified version in lightroom and paste ALL settings I have copied from the original to this new TIFF version. I expect the changes to work but it looks wrong. I notice the REMOVED tool item masks are strange. It looks like the REMOVE masks in the version that I pasted to are 90 degrees rotated - clockwise. Basically, copy/paste of masks does not work from a raw file to a tiff version. It’s like PS messed up the orientation indicator or something and LR got confused?

Mask information in LRC. Where is it stored? Does the SDK allow me to read and write to it?

I am writing a Python program that analyzes my images and gives me not only feedback about the images but editing tips. Currently it will write a new XMP file based on its findings. What is not included in the XMP file are any masking edits. Where are masking edits and their associated data stored, and are they in a place that I can access programmatically?

Lightroom v15.4 Update Broke Masking Performance, denoise and Cloud Sync

I just did the update TODAY & THIS IS THE WORST THING I’VE EVER USED. Just adding a basic backgound/subject mask is taking 20 minutes per photo and it doesn’t seem to sync. I’m not even going to start in on Denoise. I am so frustrated as I just updated, have a huge workflow and cannot edit at all. WTH is going on????

Lightroom Classic 15.4: Develop adjustment is silently reverted when applied immediately after switching photos with arrow keys

Description:When working quickly in the Develop module — applying an adjustment, navigating to the next photo with arrow keys, then immediately applying another adjustment — the second adjustment is visually applied for a fraction of a second, then automatically reverted. Both the image and the slider value return to their prior state. This is not a display/refresh glitch — the slider value itself rolls back, indicating the catalog write is being overwritten.Steps to Reproduce:Open Develop module, select any photo. Apply an adjustment (e.g., Exposure +1.0). Press the Right Arrow key to move to the next photo. Immediately (within ~0.3–0.5s) apply another adjustment (e.g., Exposure +1.0) via slider or keyboard shortcut. Observe: the adjustment briefly appears, then both the image and the slider revert to the original (unedited) state.Expected Result:The adjustment applied in step 4 should persist, as it does when waiting ~1 second after switching photos before adjusting.Actual Result:The
