The picture at the top, right of this page was scanned at 600 dpi, and I didn't get any better results with higher or lower resolution. The original photo is in great shape. In particular, the "snow" you see on the hair and long coat does not appear in the original.
The original photo has a kind of rough surface, as if someone had sprayed a liquid on it, which dried in tiny droplets. Turned at certain angle, it is highly reflective, but at other angles, it appears smooth.
