The whole reason I do my own 16mm/8mm transfers is because after years of hiring a variety of shops do them for me, I finally decided if you want something done decently you have to do it yourself. Now I see all the flaws in my own work, and worse when I see the horrors other people get back from the "local pro". So all I have to say is, although I know I can produce something very cool out of a decent 16mm print, don't expect the holy grail no matter who does the transfer - unless someone here has access to a real meticulous Hollywood top-end film scan (which I highly doubt). For one thing it would cost considerably more than the print itself, if you could even get such a shop to do it.
That said, I hope someone from this forum wins. It would be a REALLY fun project.
