iMac 15, Ventura LR exports faulty jpg

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. 

 

Right image exported from LR

Left image from PS

    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?

    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?

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