Ligtroom Classic Windows  does not merge PEF raw files to HDR - have to convert to DNG first

When selecting multiple photos and applying auto settings (Devleop Settings > Auto Settings), only a small portion of the photos have auto settings applied. This can be anywhre between 50 and 700 photos. There seems to be no logic to how many photos correctly have auto settings applied. It seems to work for more photos when selecting in the Library tab as opposed to selecting in the Develop tab.    Running Windows 10 on Lightroom 13.2. This has been happening for a couple years now.    Same as post: https://community.adobe.com/t5/lightroom-classic-discussions/auto-adjust-settings-does-not-apply-to-all-the-selected-images/td-p/13511661

Bonjour je ne vois pas comment m'abonner à LRC rien que LRC. merci

MacBook Pro M1 internal SSD 1 TB 16 GB RAM Sequoia 15.5 When assigning keywords, it sometimes happens that the input is not visible when trying to enter a new keyword because the input window becomes white and remains white. You no longer have any control over what you write or which keywords were already there before. Sometimes the error occurs after 10 photos, sometimes after 500 and sometimes never during a session. It is a different number of photos each time. By closing Lightroom Classic and open it again, the error is eliminated until it happens again. What is the problem and what can i do about it? 

I have created a DNG profile for my Leica Q3/Q343 cameras using the X-Rite ColorChecker Camera Calibration export option. I apply these profiles to the photos in Lightroom Classic. I create a collection and sync it with Lightroom. The profile shows up on the photos in Lightroom Desktop and Lightroom Mobile (I had to import the profiles into Lightroom Desktop), and also if I view the photos on the Web by right clicking on the Collection and selecting Lightroom Links, Public Link, View on Web.  I might have to be in the Edit panel on the Web for this to happen. But if you look at the photos on the Web by copying and using the Public Link, the custom DNG profile is not applied. When I apply a DNG profile which already exists in Lightroom to my photos which I didn't create, the profile is applied on the web so I am guessing that it is something to do with the fact that I created the profile. How can I make the custom DNG profiles show up on the photos on the Web when using the Public

Does the 13" M4 iPad Pro work as an HDR screen for the Develop module of Lightroom Classic when used in the sidecar mode with an Apple Silicon Mac (M1 Mac mini in my case) when the non-sidecar screen is an SDR screen (Studio Display in my case)?If it works as an HDR screen, how many stops of HDR can it do? Does the iPad Pro have to be in Reference Mode?

I have some CR3 files from a Canon R5 and they aren't being recognized by lightroom, photoshop or bridge.  I am running the latest versions of all 3 apps and the latest version of camera raw.  (ACR17)  It says that it doesn't recognize the file type.  

I have a Microsoft Surface Pro 11 with a fast ARM processor, but Photoshop will not open a photo using the edit in command from LR Classic.Is this a bug, or am I doing something wrong?

I have a plugin that uses external binaries.  I have binaries for Windows, Mac ARM, and Mac AMD that I provide with my plugin.  When I run LrTasks.execute, I need to determine which one to use.  I have searched all over the SDK, but have not been able to find anyway to determine which one to run.  Any suggestions for introspection? Paul

Since I have upgraded to Classic 14.4 I have noticed the ketwords are not uploaded to LR-Cloud Sync. I have tested with several files and purged smart previews / save metadata to files etc  (All the advice given on  google search).  Has anybody else seen this issue, and hopefully have a workaround / Fix. Classic V14.4 on Windows 10

I remember using and loving this special Touch UI mode on my old convertible laptop but one day the icon was gone. I thought this was a firmware bug with my laptop but the button is also missing on my brand new Surface Pro 11. Is there a hotkey to open it or some settings file i have to edit to get the button back?

Something else I’ve noticed about the denoise function – by the way, I’m really happy with it, especially since it doesn’t create an extra DNG file, which is great for my workflow. Maybe except for the progress window. When I apply it to a photo with a high ISO value of 8000 (using the default denoise value of 50), and then use the AI Remove tool afterward, the noise seems to come back more than in the original photo. This is also when I first use remove and then denoise.  Here are the steps with images I follow: This is a standard imported raw file  Denoise applied  Then I want to remove the yellow line in de upper right corner  The line is removed, but there is a strange effect in the place of line now  Here under a detail  I hope you can see this.

Some how Windows onedrive moved my LRC Catalog to the cloud.  I had the Lightroom catalog in my pictures folder. After several attempt I moved the Lightroom folder from teh cloud to my 😧 drive on my desktop PC.  Now when I attempt to Backup the the Catalog I get a Error... Ive tried to select my Server or other storage. and it failes  Could there be a parm incorrect?  

Hello everyone.   I have a big issue, when clearing out my laptop, i was deleting a lot of stuff. What I thought was an old backup was my current catalog and i cant recover it.   Before this happended all edit were synced to the cloud.   My question is if i begin a new catalog and allow it to sync to the cloud, will it pull down all the edits into the new catalog and from there can I just relink the images to the raw images I have. 

Hello, I'll give a bit of backstory, explain my dilemma, and describe the fix I'm attempting—but can’t seem to figure out. I set up an ingest/export folder structure for shooting. I’d been using Lightroom Mobile for about 2.5 years, but I was getting annoyed with (1) the speed of the software, (2) the lack of robust features, (3) the cloud storage space being eaten up, and (4) the inability to delete rejects from local storage. So I started using Lightroom Classic, and it solved my qualms with LrM. But unfortunately, about 3.5k images were already in Mobile, many of them edited. I spent weeks trying to figure out how to best move the edits to Classic—into the same 'ingest' folders—while maintaining the edits and knowing which were flagged to keep and which to delete. I went through discussion after discussion and found there was no smart, easy way, so I brute-forced it. I set up empty folders on my local drive and manually copied over the ~3.5k images from the synced 'Collect

Hello, I have been meaning to purchase a new computer for a few years now, as my 2012 iMac 27" just wasn't able to process most functions any longer and certainly not Lightroom 5. I was able to download and install Lightroom 5 onto my new Mac Mini, but when i submitted my serial number to register the product, Adobe rejects it. The application still seems to "function" but I have come to realize it's no longer supported. I wanted to simply migrate my Lightroom catelog from my old iMac to my new Mac Mini and start catching up on the last few years of photos.    I'm a hobbyist and mostly just have family photos and sightseeing. I'm not a professional. I just want to be able to use the software I purchased. If i MUST subscribe, I can...but $240/yr for a hobby seems....steep.    Seeking any help or assistance from the community on the best way to move foward here.    Summary:   1. Old 2012 iMac 27" with LR5 that has thousands of photos. 2. Brand new power

Heard a comment from a respectable photographer that LrC could run into a 'won't run' issue with about 5TB of images referenced, irrespective of the size of the .lrcat file itself.  Is this true (I have already exceeded this so worry that I'm on thin ice now)?  Or is the limit on previews?  Or anything else?  Or is this urban legend from someone with a corrupt catalogue?thanks, Bill

Faz um tempo que não consigo usar a Remoção Generativa usando a IA.Já desistalei e instalei e mesmo assim não resolve.V 14.0.1

intensité du cache quand on selctionne une photo de la grille.   sur les anciens diapositifs il y avait une partie image et une partie cache en plastique ou en carton. sur lightroom quand on selectionne une photo ce  cache est plus sombre quand la photo est sélectionné. etant malvoyant je ne vois pas la difference si une photo est selectionné ou non selectionné. ma question peut-on modfier la couleur ou l'intensité du "cache" selectionné?   merci de vos réponses.

I just started using an identity plates to "sign" my work for shows.   I use custom text.  It works well for landscape orientation -- the text shows up as expected with the baseline near the bottom and reading left-to-right.  When I switch to portrait orientation, the text rotates 90 degrees clockwise, so the baseline is along the left edge and it reads top-to-bottom.   I can find no way to rotate it back to "normal".    Is this a known limitation or am I missing some simple way to have landscape-oriented identity text in a portrait print?

I'm using LR Classic and I'm not seeing the latest features, particularly Remove People and Remove Reflections.  I presume this means I need to update? How do I do that.  I've seen a link in a previous post to an LR Install site, but I'm concerned to do this incase it affects my catalogues etc.  Thanks very much. 

It's 2025.07 and this problem still exists. How hard could it be to fix a slideshow feature in the "leading" photo editing software... ?!@Adobe Team - that's not cool.
