Hello dc3 and John,
The scanner I used is a Nikon Coolscan V ED with the standard program supplied by Nikon. The film used is Velvia 100. I don't remember which lens I used, but it's either a Summicron 35 mm or an Elmar 50/2.8 (old version from the early 1960's).
I'm not familiar with Vuescan, so this is maybe a silly question, but is it a better choice than the Nikon software?
