Nikon's s/w no matter the setting for it's clipping zones is quite aggressive
in  setting levels and contrasts. While Hamrick's VueScan is not without its
quirks, I find myself using it more and more often over NikonScan because I
get a much much wider range from it than from NikonScan. There's detail in
shadows and highlights in VS that I canNOT get with NikonScan w/o a great
deal of work. Note that this may be different for LS-5000/9000 users since
Nikon's s/w has a few extra options for those scanners to do with
shadow-detail and highlights.
