The file saved from NikonScan has a smooth histogram above a certain bin, a
high value in that bin, and nothing below it. If I scan the same film with
VueScan, the histogram has a smooth tapered tail on the left side. I made
these comparisons using the histogram display in the Photoshop levels tool.
If I remember right, this happens mostly with negs, but I have not used
NikonScan regularly for a while, so I could be wrong.

Yes, sometimes it's quite surprising. It's fun to scan shots from years ago
that I considered to be botch jobs, and rehabilitate them by yanking curves
in Photoshop. I made a simple page to show some friends of mine a demo of
this digital voodoo.
