filmscanners: Silverfast problem

[Martin Greene <camerabuggy@earthlink.net>]

Scans I made using Vuescan with my new SS 4000, after much assistance from
members of this forum, were crisp, sharp, and had colors that were very
close to my slides.  I liked the Silverfast interface, felt it was visually
most attractive and liked the sophistication of its controls.  But, I was
unable to get a crisp, sharp scan.  Scans simply did not look sharp.  On my
Mac G4, I used version 5 and also downloaded and tried the trial version of
5.5.  I faithfully used Ian lyon"s tutorial to set it up.  I found it
strange that I couldn't get a sharp scan.  I very much would have liked to,
and don't understand why I couldn't.  Perhaps, I'm doing something wrong?
I'd appreciate any suggestions for overcoming the difficulty I encountered.
Let me know if additional information would help.
