Les Sarile, The result of Noritsu is above. I did not any special Nikon scanner for minilabs. Simple the lab I used provides scannning by Noritsu or Nikon scanner for consumer choice.
Unfortunately, this is confirmation of what you already said earlier that even with light behind it there was nothing to see.
I tried some shadows post work on it and there wasn't anything to be gained. I doubt an uncompressed file format would have yielded any more.
Because these are old family photos, I can appreciate the effort to salvage as much as you can. I once had someone bring me some old family pics on Kodachrome that were much better exposed but unfortunately all mildly out of focus.
