Multipass results are most useful when you have noisy shadows.  By
adding up several scans, the random noise is averaged out of the scan by
software.  If the scanner has very good dynamic range which extends into
the shadow areas, you won't miss this  (the Polaroid SS4000 is reported
to not "need" multi pass scanning, for instance).

I haven't kept up on Vuescan's full abilities, but Ed might have
programed the ability to use multipass with the Nikon IV.  I think he
was successful in doing so in an earlier "lower end" model.  Ask about
this from someone using the scanner with Vuescan.
