Thanks Ernst, I'll check this out next time I'm scanning.  As I said in a
previous post I see no actual clipping of color neg shadows in the scans
I've done to this point, only remapping of the black point higher.  So my
thinking to this point is Nikonscan deliberately maps color neg black point
high while retaining linear detail to film base for a reason: to allow the
user to set it as desired with accuracy.  This is the region in color negs
that varies considerably with exposure (as opposed to chromes), and
automatic mapping to zero from a film base reading would only work with
"correct" exposures.  The way I would suggest working is to set the black
eyedropper to 10 (or whatever you prefer since many shadows are blue), find
that point in the neg, and the scan mapping to that point will occur in
Nikonscan in hi bit, making further hi bit edits in Photoshop unnecessary.

Perhaps I'll change my opinion after trying it the other way, we'll see.

Dave
