I seem to experience a mysterious issue when Lightroom creates an Edit Tiff for external editing. I have this issue only with one picture it seems. I tried to replicate it with another, but it doessn't happen.
So here's what happens. I already had an Edit.tif of a DNG. Then I noticed I wanted to do some final retouching in Photoshop with the healing brush, but I also did some minor adjustments in Lightroom on the Edit.tiff, so I decided to create an Edit-Edit.tif.
Then when I went back to Lightroom, I noticed the Edit-Edit.tif was all of a sudden lighter in the shadows than my Edit.tif.
I tried some trial and error investigation myself, to replicate the issue. I couldn't replicate it with other pictures. But when I tried to do the same thing again, except this time no Photoshop editing to the Edit-Edit.tif (so Photoshop didn't ask me to save), same thing happened. So at least I found out it doesn't have anything to do with Photoshop.
Anyone any idea what this could be? I would greatly appreciate any help! Thanks in advance!
Problem is solved. It turns out, it probably has to do with the interpolation mechanism of Lightroom displaying dark area's with color noise a litte different.
Thanks anyway for reading!
