Here's the system info for my studio computer (one month old), which has an Intel(R) Core(TM) Ultra 7 265K processor. My home computer (one year old) has an i9 processor, 64 GB RAM and an RTX 3060 with 12 GB RAM. The LrC catalog is on a fast M2 disk on both computers, and LrC performance is about the same on both.  Note that these are desktop computers – not laptops.   Lightroom Classic version: 15.0.1 [ 202511041508-dddee541 ] License: Creative Cloud Language setting: en Operating system: Windows 11 - Business Edition Version: 11.0.26200 Application architecture: x64 System architecture: x64 Logical processor count: 20 Processor speed: 3,8GHz SqLite Version: 3.36.0 Adobe GSDK Version: 1.4.0.171   CPU Utilisation: 0,0% Power Source: Plugged In Built-in memory: 64865,3 MB Dedicated GPU memory used by Lightroom: 543,3MB / 16050,0MB (3%) Real memory available to Lightroom: 64865,3 MB Real memory used by Lightroom: 1164,6 MB (1,7%) Virtual memory used by Lightroom: 2068,6 MB GDI objects count: 816 USER objects count: 2769 Process handles count: 2913 Memory cache size: 84,2MB Internal Camera Raw version: 18.0 [ 2389 ] Maximum thread count used by Camera Raw: 5 Camera Raw SIMD optimization: SSE2,AVX,AVX2 Camera Raw virtual memory: 107MB / 32432MB (0%) Camera Raw real memory: 114MB / 64865MB (0%)   Cache1:  Final1- RAM:61,0MB, VRAM:221,0MB, Såheim stasjon 1.tif NT- RAM:61,0MB, VRAM:221,0MB, Combined:282,0MB   Cache2:  m:84,2MB, n:58,2MB   U-main: 123,0MB   System DPI setting: 96 DPI Desktop composition enabled: Yes Standard Preview Size: 1440 pixels Displays: 1) 1920x1200, 2) 1920x1200 Input types: Multitouch: No, Integrated touch: No, Integrated pen: No, External touch: No, External pen: No, Keyboard: No   Graphics Processor Info:  DirectX: NVIDIA GeForce RTX 5060 Ti (32.0.15.9144) Init State: GPU for Export supported by default User Preference: Auto Enable HDR in Library: OFF GPU for Preview Generation: On (S5_15)   Application folder: C:\Program Files\Adobe\Adobe Lightroom Classic Library Path: D:\Dropbox\Lightroom\PB-v15.lrcat Settings Folder: C:\Users\xxx\AppData\Roaming\Adobe\Lightroom   Installed Plugins:  1) Any Shortcut 2) Helicon Focus Export 3) LensTagger Exif Tool 4) Topaz Photo AI   Config.lua flags:    Adapter #1: Vendor : 10de Device : 2d04 Subsystem : 812b1462 Revision : a1 Video Memory : 16050 Adapter #2: Vendor : 1414 Device : 8c Subsystem : 0 Revision : 0 Video Memory : 0 ...

Richt click the Intel UHD Graphics 750 and choose Disable.   For the record, I find version 15.0.1 to be faster and more responsive than version 14. In fact, I can't remember any version running so smoothly, and I've been using LrC since version 2 in 2008. ... View more

I agree with what others have said here – your catalog file is very small, considering the number of photos you have. I have almost twice as many photos as you have (56k), and my catalog is four times bigger than yours, 1.65 GB.   my use of LRC is really simple so I don't want such a big file By @willdizzy   The catalog size is what it is, regardless of how you use LrC. And 400 MB is nothing compared to the preview cache, which will be several GB. (mine is 36.8 GB) ... View more

Hello again. I will try to explain it with images. If I'm going to look in the windows folder where all the ICC profiles are, there it is saved correctly (image 1). But if I go to "import profiles", by default from LC I get an erroneous default path (image 2). And when I manually correct the path, I get the empty folder (image 3) By @yolanda_7308   Screenshot 3 shows a window titled Importar perfiles y ajustes preestablecidos de revelado, which translates to Import profiles and development presets, and the file file format is XMP, as can be seen in the bottom right corner.   The EPSON 9900 Hahnemuhle matt fibre is an ICC profile used for printing, and cannot be imported in LrC. The purpose of this ICC profile is to ensure correct colors when printing. You can use this profile when printing from LrC, and you can also soft proof using the profile in Develop. You don't (and can't) import ICC profiles – they will do their job as long as they exist in the correct Windows folder, which your profile does.   ... View more

Thanks for the answer. I already explained it in the first question I asked. The profile is installed correctly in the path you indicate from Windows, however when I do it from lightroom... that folder is empty... And I also have to put the path manually because by default from Install Profile in Lightroom, it takes me to another path. By @yolanda_7308   You cannot install ICC profiles from within LrC.  ICC profiles that are installed in Windows will appear in LrC when soft proofing in Develop, and in the Print module. CMYK profiles will not display, only RGB profiles. What is the name of the profile? ... View more

why is non classic lighroom so slow? By @Jason24089307xdoo   Does this mean that you are not using Lightroom Classic? You have posted in the Lightroom Classic forum. So are you using Lightroom Classic, or the cloud version, which is named "Lightroom" ? If it's the latter, a moderator will move this thread to the Lightroom ecosystem forum.   Edit: I see now that you've posted in the Camera Raw forum, which is for the Camera Raw plugin for Photoshop. So your post will be moved to either Lightroom Classic or Lightroom ecosystem, depending on which one you're using. ... View more

Version 21.4 doesn't have this issue, only 21.5 and 21.6. ... View more

Hi Nancy, I have disabled everything related to spellcheck in Windows. (I always disable it in all programs) The problem only appears in Dw versions 21.5 and 21.6. This is on Windows 10 as well as 11. I don't know if you're still using Dw, but if you are, are you not seeing this? You need to click some text in Live view to see it. When you click outside the text, it goes away. ... View more

I have tried several of the 21.x versions, and it turns out that this "feature" was introduced in 21.5, so there should have been plenty of time to get it right. If it is a feature, it seems to indicate that there is some development going on, after all. Anyway, I solved the problem by installing version 21.4. ... View more

It turned out that I had version 21.3 on the Windows 10 computer, not 21.6 as I thought. I updated to 21.6, and the spell check issue appeared, just like on the Windows 11 computer. So I suspect that this is a bug in 21.6. ... View more

This seems to be colons, not slashes. Both should be avoided, and the colons might be the reason that LrC doesn't import. To be on the safe side, use only letters a-z, numbers 0-9, hyphen and underscore in file names.   ... View more

Are you absolutely certain that color management is disabled in the Epson driver? "Double profiling" will lead to wrong colors in your prints.   Your monitor profile (display profile) is listed as ASUS VE247-1. If this is not the profile you created with calibration, it is a canned profile from ASUS, installed with a Windows update. Profiles from monitor manufacturers are notoriously bad, and often defective out of the box. When you print an image, the colors are converted from the monitor profile to the printing profile, and if the monitor profile is bad, the conversion might go wrong. I suggest that you recalibrate, note the name of the new profile,  and make sure that the it is being used by Windows. Go to Control panel > Color management > Devices tab to check.   Also, your  GPU driver for your RTX 4070 is 15 months old. The GPU carries out the profile conversion, and bugs in the driver can affect the conversion. Dowlad the latest Studio driver from this page (do not use the Game ready driver) and install it. https://www.nvidia.com/en-us/drivers/details/257327/ ... View more

You're not going to lose anything. The catalog and your photos are unaffected by a reinstall. If you are given the option to keep the preferences when uninstalling, I suggest that you don't keep them. By deleting them you'll be starting out with the cleanest slate possible after the reinstall.   If you have changed the preferences since the first time you deleted them, you can take screenshots of all the tabs in the Preferences dialog, which will make it easier to restore them later. ...

The contrast in this scene is very high, and the subject is in the shade. So you have to lift the shadows considerably, and this will inevitably lead to noise, even at ISO 400. The reason is that shadow pixels have much lower quality than midtone and highlight pixels, and this low quality is revealed when you brighten the shadows. See this article for a detailed explanation: https://perberntsen.com/misc/technical/exposing.php   The noise is also enhanced by a number of your edits: Positive Texture and Clarity values A high Sharpening radius. You had it set to 2, I reduced it to 0.5. Sharpening masking will protect flat areas (where noise is most visible) from sharpening. You had it set to 0, I used 90. (hold down the Option key when dragging the slider, and you'll see the effect. White Black areas are protected from sharpening, white areas will be sharpened) You had Color set to 7 under Manual noise reduction, I increased it to 30, which removed the color noise.   Many of the Develop settings you have used are created on import because Nikon mirrorless cameras write camera settings to XMP which LrC understands and honors. I use a Nikon Z7 myself, and find these settings useless. To stop this from happening, either zero out all settings in the camera, or create a Develop preset that is automatically applied on import. You can either create your own preset with the sliders set the way you want them, or just use Adobe default. See https://helpx.adobe.com/lightroom-classic/help/raw-defaults.html   You can download my version of the image here: https://per-berntsen.filemail.com/d/sfztbrbsbextqfh It is still has a bit of luminance noise that you can remove with DeNoise or manual noise reduction. ...
