Question

Sometimes, maybe. 1 in 10 when I edit in another program, LR does not properly make a copy with Lightroom edits. It will sometimes even make the copy of a version prior to some final edits I made. It’s almost always. a much brighter version of what it should have done. You can look at the copy and original and they are not the same.

    External programs include Evoto and Topaz Photo AI. Has happened to both. Latest version of Lightroom Classic. Latest version of MacOS. Apple silicon. See screenshots. Look closely at the side by side and you can see the edit.tif is brighter. It should be exactly the same as the other. That right after Lightroom made it, no work was done to it yet in the external program.

    It’s worth noting that I deleted the edit.tif in both LR and Evoto and redid it EXACTLY the same way, and it was fine.

    Very strange. I can’t reproduce this, because I don’t use Evoto and I’m on Windows.

    On the other hand I also use Topaz Photo AI and I don’t see such differences.

    What I see is you use sRGB as color space. I consistently use ProPhoto in Lightroom and all external tools. Only when exporting from Lightroom I set the appropriate color space, mostly sRGB.

    Try using ProPhoto and check if this something changed.
