iMac 15, Ventura LR exports faulty jpg

[Pablo Federico]

Bad images exported from LR
Maybe using Ventura is somthing missing on latest OpenCore.

Changing all the sets about my GPU does not did the tick, if I export from PS everything works fine, the same file in Lightroom looks awful.

iMac late 2014 27 inches.

¿anyone has the same problem?

One is a 16 bit TIF file and the other an 8 bit JPG so I'd expect to see some miniscule differences between the two, but maybe I'm not seeing what you're seeing. Is it the black level you're referring to, in the JPEG?

Which Lightroom version are you using? If it is v13, can you roll back to v12.5 and compare?

[Pablo Federico]

Rolling back to LR 12... make the trick.

Thanks

The images  look identical when viewing your screenshot at 100%.

You are comparing them at 50% view in Photoshop. To do a real comparison, view at 100%, where one image pixel is represented by one screen pixel.

If there is any reduced quality caused by jpg compression, it will become apparent at 100%. (if you have a 4k monitor, you might have to use 200% to spot the difference).

If you see a difference, it is not a difference between PS and LrC, but between a 16-bit tiff and a jpg.

Here the two images in JPEG version on a 5k monitor.

Maybe I miss to explain something.

The "jpg LR" looks like it's half a stop lighter.

You're exporting both of them in the same color space?

[Pablo Federico]

Yeah, same color space.

One in PS one in LR 13. But everything works fine with LR 12.5

[Per Berntsen]

The two images are not in the same color space, the title bar for the LR image says (RGB/8*), and the asterisk means that it is in a different color space than your RGB working space.

This is normally not anything to worry about, since color management should make sure that the image displays correctly .

But do tell us what profile the LR image has embedded. Click the arrow bottom left of the document , and choose Document Profile.

Also please post a screenshot of the LR export dialog with the settings you used to export the image. Make the dialog the full height of the screen, so that we can see all the settings.

Do not attach the screenshot, use the Insert Photos button in the toolbar to insert it directly in your post.
