Don't flagelate yourself too harshly Austin. Rob Geraghty started this
thread by talking about the Nikon LS-30, which DOESN'T support
single-pass multi-scanning. In a few trials with my LS-30 and Vuescan
multi-pass multi-scanning I found only a slight loss of sharpness, and
not much benefit in shadow detail either. Scan times, of course, were
longer...
