AI Denoise creates rectangular artifacts in smooth sky areas.The artifacts are not limited to the Lightroom preview. They are permanently written into the generated DNG and remain visible in Photoshop and exported JPEG files.The artifacts become much easier to see after increasing the Dehaze slider, but they are already present in the DNG.I reproduced the issue with:- Canon EOS R6 Mark II (CR3)- Canon EOS R5 Mark II (CR3)- iPhone 17 Pro Max (DNG)The issue occurs in both Lightroom Classic and Lightroom Desktop.Disabling GPU acceleration does not change the result.SystemLightroom Classic 15.4.1Camera Raw 18.4Lightroom Desktop 9.4.1macOS Tahoe 26.5.2MacBook Pro 16"Apple M4 Pro48 GB RAMSteps to reproduce1.

I would like to add some text to my photos after I edit them in lightroom CC. Like, I do bird photography and I want to add the bird name in a corner of the photos. How can this be done? I have attached an example. The only way I have figured out is to add such text as a watermark, but that is not my intent.

:I can't open Lightroom CC on my MacBook Pro M1 Max 64gb ram 4tb hard drive

I click on my Lightroom button to open it on my Mac and it bounces once and then stops. Nothing opens. I’ve tried reseting the starting option. I’ve reinstalled it. And have tried other tricks recommended online. Nothing will open my Lightroom app… 

It works fine for a few days and then won’t open.  Task Manager says it is running but I see nothing.  What gives?I should mention my catalog is huge … don’t know if that has anything to do with it.

I was editing wedding photos without issue, when suddenly I get this black overlay show up when I did a mask instead of red.   I thought maybe I pressed something that caused the default red to change so I went ahead and did my edits, but then the photo remained with a black muted color on top of it.  I tried choosing a different color overlay color, but with the same result.  HELP PLEASE!! I need to deliver these photos to my client.  Thank you!  

Hey there, currently I'm trying to improve my understanding of the RAW development pipeline in lightroom and Camera raw. I am interested in the order of adjustments that are made to an image if I adjust the sliders. Not in the recommended order that people suggest for their workflow to be efficient, but in the order they are implemented in lightroom by adobes software engineers. In Adobes dng format documentation for developers I found that white balance is applied first to an image before it comes to exposure, contrast and so on. For all other adjustments the order is not given. Contrast can be adjusted using the contrast slider and also using the luminosity tab in the tone curve. Since these adjustments are not linear it makes a difference in which order they are applied. I can emulate this process in photoshop if I apply two adjustment layers to a photo, 'Brightness/Contrast' and 'Curves'. If I switch their position the outcome will differ in general. So also in light

Adobe Lightroom 15.4.1 is crashing repeatedly during the culling process and causing my  pc computer to run terrible slow.  I had to remove it and roll back to a previous version of LRC

When an image is leveled, the crop tool's boundaries are restricted to the rotated canvas to avoid empty corners. However, if I try to expand the crop rectangle toward an area where there is still room, it gets blocked by the opposite edge that has hit the canvas limit. It would be a great improvement if the crop rectangle could automatically shift or slide along the boundary so it can be expanded into the available space, utilizing all available pixels without needing to manually reposition the corner or center handles.

When importing photos, Lightroom Classic sees to card, but only pictures on one of them. Then copy the pictures ad try to sync the catalog. Same problem. LR read raw cr3 from canon R5, but not dng files from DJI Mavic2 pro!What to do?

This post applies to Lightroom Classic and the Lightroom Ecosystem products. Camera Raw feedback can be found here.   Generative Remove makes it easier to remove unwanted objects and distractions with a simple gesture, even on complex backgrounds. For more accurate results, be sure to include the object's shadow in your selection and/or expand its size.    Detect Objects uses AI to find the objects underneath a brushed area. The masked areas will now appear larger than the Early Access version of this feature. You can also circle objects for quicker selection now.    We have also updated the spot selection experience to make it easier to manage variations, switch the fill type, refine the selection area, or re-generate as needed.    Batch updating is also now supported for Generative Remove spots.    Try out the latest updates and share your feedback with us here. Please also include the following details in your post:  App versi

When I switch to the developement modul, the warning sign in the thumbnails don’t show anymore. When I switch back to Bibliothek, they show again.How can I get rid of the red symbol with the white "X" on my thumbnails in the bibliothec modul? All pictures are correctly connected on the hard drive; lightroom can show them in the finder. Is it a problem with the new analyzing tool? 

hola, el LR en el dia de hoy no funciona? no puedo editar ninguna foto. cuando se solucionara el problema? la actualizacion se hizo hace 16 dias

I got the 20GB subscription. Since a long time I get warnings about it being full. I have tried everything suggested on your site. Including looking for files on the computer. Have only two photos when I check. My son previously used the other seat when I had the subscription that included Illustration.  Could it be that big files are left from that?

Hello Dears, I have a problem with synch. Last night I tried to synch with 493 photos. Most of development setting was Ok but some of ones missing and/or not correct. For example; linear mask starting point, color adjustment and crop position are different some photos.I tried remove all 492 photos in lightroom and called again. I kept original one which is modified than I tried synch but no change. Issue still there. Is there anybody to face same situation and know solution. I’m using creative cloud desktop version. Thanks in advance for your help.

Summary: Lightroom Classic throws a generic "unknown error" when importing HEVC video files tagged as hvc1, which is the default output format for DJI cameras (tested with DJI Osmo Action 6). The same file remuxed to use the hev1 codec tag imports without issues. No re-encoding is performed — the video bitstream is identical.Steps to reproduce:Record video on a DJI Osmo Action 6 (or likely any DJI camera outputting HEVC). Or use attached input file.

Hi Adobe Team, I’m posting this as a clear performance regression report for Lightroom Classic v15.x — specifically the Develop module image-to-image switching latency on Mac. REALLY SLOW. Please do not merge this thread into a generic “performance” megathread and then mark it as “Solved” as if nothing happened. Multiple users are reporting the same behaviour, and it deserves a proper investigation and acknowledgement (instead of being dismissed as an “NVIDIA driver” issue — this is Apple Silicon). What’s happening On Lightroom Classic v15.2, switching between photos in Develop is several times slower than in previous versions. This is not a minor “feels slower” issue — it’s a real, repeatable regression that drastically impacts professional workflows. My setup  MacBook Pro (M3 Max) macOS v26.2 Lightroom Classic v15.2 Preferences → Performance → Graphics Processor: ALL acceleration options manually enabled (not Auto)  Proof / Reproduction To remove any subjectivity, I recorded sc

This post is applicable to Lightroom Classic. ETAs for tethered support for specific cameras are not available.   Tethered Capture is a feature of Lightroom Classic that allows the direct connection of your camera to the Lightroom desktop environment. Images are imported into your Lightroom catalog as they are captured via the connected camera. New camera support for reading the raw files is generally added quickly after a camera is released by its manufacturer.  New camera support can be verified here: https://helpx.adobe.com/camera-raw/kb/camera-raw-plug-supported-cameras.html.  Tethered support for a particular camera model normally follows a version or two after the raw file support. Adobe relies on the manufacturer’s (Nikon & Canon) SDK (Software Development Kit) to facilitate the tethering of your camera to Lightroom. The timing of the release of a manufacturer’s support via their SDK greatly affects the time to release for tethered support. In additi

Since the recent updates I have intermittently experienced a number of issues when using Lightroom Classic 15.4.1 on a Windows 11 PC (System info below):program crashed on one or two occasions; program switches from Develop to Library mode by itself;  clipping indicators show in green rather than red;  ‘Before’ image does not appear when selecting Before / After; Masking fails to find landscape features, subject or object and pop-out closes; Adaptive colour profile does not work.None of these issues were present before the update, and I tried the masking in Lightroom (desktop) without problems on an image where LR Classic failed to find the subject or landscape features. I have tried switching between ‘use graphics processor’ and ‘off’ but it does not seem to make a consistent difference - sometimes things work as expected, the next time they don’t.Lightroom Classic version: 15.4.1 [ 202606201310-b9f148a4 ]License: Creative CloudLanguage setting: enOperating system: Windows 11 - Busine

I am using an Apple studio computer.  In both the Library Module and in the film strip, when selecting a file, the next file is also selected.  When trying to scroll through the other pictures in the folder, it only scrolls between the selected two files.  This problem started after updating to the latest version of Lightroom Classic.  I can only advance by using my mouse to click the next file.  Then it will also select the file next to it.Does anyone else have this problem.  If so how did you fix it?

How do I get Lightroom to write the metadata directly into the original jpgs?In my Lightroom catalogue are two folders with images from my smartphone (Pixel 9 Pro). One contains the original jpgs plus dng raw files of some of those images. The second folder holds images edited on my phone with Snapseed. I use Lightroom to edit the keywords and filenames.If I add keywords to a Snapseed edited photo those keywords are immediately written into the jpg image but if I do the same for an original photo the keywords are stored in a xmp file. Even if I manually ask Lightroom via right click Metadata > Write Metadata to file all I get is a xmp sidecar.
