Hi Klaus,
I still don’t see your “kind of double exposure overlay.”
Out of curiosity, I went to experiment with the relatively new AI – and started from scratch. Well, twice, because to my surprise, PL initially ran without crashes … until later that same day. I must have made some conflicting settings, that I could not detect. So I deleted everything and started over.
see _KLS5062.NEF.dop (1,7 MB) → VC 1
In the meantime, I also updated to PL 9.4.0_437 and checked about the “Export to Nik Output Sharpener” option(s) …
.
At first, I corrected some Perspective, cropped to 4 x 3, used SmartLighting / Spot weighted, Tone curve / Luminosity / Gamma and White balance
before I went with Local adjustments.
.

reducing highlights
.
AI mask (Subject) to cover the band
+positive Auto brush to add to the selection
( tried to improve the “capture” of the blurred foreground )
.
duplicated AI mask (Subject) from Mask2
+negative Brush to subtract from the selection
( tried to improve the “capture” )
.

some additional ‘sharpness’ for the front
.
some softening to better separate the band from the background
reused + inverted AI mask (Subject) and Auto brush from Mask2
+Auto brush corrected
.
Yes, it was a bit fiddly ( the window for the Local Adjustments is too short ),
but PL didn’t crash anymore.
