The software maps the input range into the 8-bit video. Different settings
in VS give different OD ranges. Nikon negative setting is mapped to give a
higher contrast than VS normal negative setting. Of course you can adjust
this with brightness and curve adjustment. NS3.0 has a different mapping
for Positives than NS3.1, the latter giving wider OD range.
