The first image has only a tiny bit of noise, so using Denoise at 50 is way too much. Try using a much lower setting, like 10, and see if that cures the red cast. I imported the two images in LrC, and using manual noise reduction set to 10 worked fine for me. For moderate noise like this, manual noise reduction works quite well. It's fast, and you can do it on the original image with no need for a new file.   To evaluate noise and sharpness (and other image detail), always view the image at 100%. (use 200% if you have a 4k or higher monitor). This is the only magnification that shows you a true rendering of the image – on image pixel is represented by one screen pixel. Unfortunately, Denoise presents you with a preview at 250%, which I find useless. ... View more

I'm seeing something similar when I try to save a small file, 39 kb ends up as 48 kb. The file size you see in Save for web is obviously an estimate, since the file hasn't been created yet. And frankly, it doesn't matter if a file is 38 or 53 kb. Both files are very small. The estimated file size seems to be more accurate for larger files. ... View more

I exported an image from raw format to jpg - in the same export file. But it doesn't show up in lightroom, only on my hard drive. How can I make it visible in Lightroom? Thank you very much By @karen_3943   In the Export dialog, check Add to his catalog.   ... View more

I see in another thread that you're using a Nikon camera. I have a Nikon Z 7, and I usually work with the histogram enabled in the viewfinder. It's quite small and not too intrusive. If you have a Z camera, press the DISP button on the back of the camera one or more times until the histogram appears.   The histogram does not show RGB channels and refers to a jpg, not the raw file, but it gives you an indication of possibly blown highlights. If the histogram is bumped up to the right, the highlights will be blown in the jpg, but possibly recoverable in the raw file. To be on the safe side, reduce the exposure a little, so that there is a little space on the right side of the histogram. With some experience you'll be able to tell how much you can expose without blowing the highlights. I have found that in some situations, the histogram will indicate a badly overexposed image, while the raw file is fine. In other situations it's the other way round. This will vary with the lighting conditions and the quality of the light, so you can never know for certain how far to the right the histogram can be. I suggest that you take a lot of test shots in different lighting conditions.   For more information, see Exposing a digital image. ... View more

A moderator has moved your post to Discussions because this is most likely not a bug. I'm on Windows, and created a folder named æ'øåéç and imported an image from it. LrC has no problems with this folder.   2) copy the catalog, associated LR files and the main pictures folder on a usb drive If this is a thumb drive, it might be the cause of the issue. Thumb drives are known to be unreliable.   In the past, the general advice was to only use characters a-z, numbers 0-9, hyphens and underscores in file and folder names, especially on the Internet. Other characters were considered "illegal", and Internet Explorer would not display images with illegal characters in the file name. This has obviously changed, but I think I saw a post recently about LrC complaining about illegal characters in the folder path on a Mac.  Maybe @johnrellis can tell us something about the status of illegal characters. ...

The .dropbox.cache folder is probably hidden. Turn on Show hidden items in the File Explorer, and it should display. While it is possible to have the catalog in a Dropbox folder (requires  a lot of caution and following some rules strictly), the cache folder is not the place to keep it. This folder is used internally by Dropbox, and should not be used for anything else. I have a folder on Dropbox named Lightroom where I keep the catalog folder. To avoid catalog corruption and other problems, the following rules must be followed strictly. Before turning the computer off, make sure LrC is closed, and wait for Dropox to finish syncing. Do NOT turn the computer off before Dropbox has finished syncing. After turning the computer on, Dropbox has to finish syncing before you launch LrC. Do NOT launch LrC before Dropbox has finished syncing. In Dropbox preferences > Sync, Save hard drive space automatically must be turned off. Default sync state for new files must be set to Available offline. The path to Dropbox must be the same on all computers that you use. If it is D:\Dropbox on your main computer, it must be the same on your other computers.     When I reconnected the 4 to drive after getting back home it would no longer link to the catalog. By @philr51159246   When you connect an external drive, Windows will assign the first available letter in the alphabet, which may not be the same letter the drive had the last time it was connected. For instance, it the drive letter was previously D, and Windows assigned E, LrC will not be able find neither the catalog nor the images. (if they are on the same drive) It is possible to change the drive letter back to what it was, if the letter is available, or assign a letter at the end of the alphabet, which is not likely to get changed. However, this could create issues for Dropbox if its path points to a different drive.   Please give us some details about your workflow. Do you have one or several computers that you use with Dropbox? Is the catalog as well as the images on Dropbox? And are the catalog and images on an external drive that you move between computers? ... View more

The jpg format uses lossy, destructive compression in order to create small files. A low quality setting will result in a small file size with visible compression artifacts. Flat areas, like blue skies are prone to banding. A high quality setting will result in a larger file size with few compression artifacts. A quality setting of 85 is considered optimal for image quality. Using a higher setting will not improve image quality, but the file size will increase.   Note that even at quality 85 or higher, there is still some loss of image quality, but it may be hard to see. I have some images with cloudy skies with a lot of fine gradients, where I get color artifacts even at 100 quality.   For more information on file formats, see https://perberntsen.com/misc/technical/fileformats.php Here's an article on jpg quality settings in LrC: https://regex.info/blog/lightroom-goodies/jpeg-quality     Quality 0, 78 kb   Quality 30, 142 kb   Quality 60, 229 kb   Quality 85, 796 kb   Quality 100, 1.16 mb ...

I have no idea what's causing this. Can you confirm that you're still seeing it when viewing the image at 100%?

Camera settings would be a good candidate here, but since the original is a jpg, it can't be that. A jpg should look roughly the same in the import dialog (which is not color managed btw) and in Library/Develop. There's a good match between the histogram and the brightness of the image in LrC, so this is clearly a correct rendering.   @mateus_0264  I have no experience with HDR, but do you have HDR (HD colors) enabled in Windows display settings?

First of all, leave the image in its existing color space. The colors will be automatically converted to the printer profile in the printer driver. In the PS Print dialog, set Color handling to Photoshop Manages Colors. Then select the correct printer profile from the dropdown list. Color management must be set to Off (No color adjustment) in the Epson driver, if not, you will get "double profiling" and wrong colors.   I am not familiar with Epson print layout, but I imagine that it has a way to turn off color management.   ...

Hello, when I want to "export as" my image in Photoshop PDF format, I am not offered to change the ICC profile. The Adobe site specifies that there is a Color tab allowing you to do this but it does not appear in my home. I'm on Mac Mojave 10.14.6 and Photoshop 22.5.9. Thank you for your help! By @Christo King   You are using Save As, which does not let you change the embedded profile. When using Export (or Save for web) there is an option to convert to sRGB (which should always be checked, as well as Embed profile), but no option to convert to any other profile.   To do what you want, you have to convert the profile before saving. Edit > Convert to profile. After saving, you may want to go back one step in History to keep the original profile with the original. Alternatively, make a duplicate of the image (Image > Duplicate) that you convert to a different profile, and then do a regular Save. ... View more
