Nice shot.

So I played around some more with some Kodachrome slides.  Scanned one 
thinking by accident that it wasn't Kodachrome and scanned it with the 
'positive' setting.  Once I realized my mistake, I scanned it again using 
the Kodachrome setting in Nikonscan.  Lo and behold, the picture was 
significantly bluer when scanned on the non-Kodachrome setting.  It was 
correctable, and while the one scanned on the correct setting was much 
closer to the original, it still needed a bit of correction.

 From what I recall of the color settings in Vuescan, there's no Kodachrome 
setting.  I've read that the yellow dye used in Kodachrome looks differently 
to our eyes than it does scanner electronics - probably something to do with 
the spectral width and shape of it.  As a result, your scans come out 
blue/cyan.  Anyway, if your software doesn't account for it, you probably 
will have to in post.  Nikonscan does some to account for this.  Vuescan 
probably doesn't.  I think Silverfast does.
