Hi, Paul,

I have summed it up graphically in a JPG picture you'll find at
http://schmode.net/nikonscantweak.jpg, accompanied by some comments 
on what is done and why.

No, I set both of them to 0.0. And, maybe more important, CMS off - I
found Nikon CMS to act very unpredictably with negatives, so my choice
is plain sRGB. Before I forget, even more important is to set "preview
mode" in the "scanner extras" menu from "auto" to "lo-cont neutral"
which will prevent some weird Nikon automatics from producing blown out
highlights. Without changing that menu item, you'll probably get blown
whites inrespective of any other settings you choose!

It's all explained in the picture (I hope). Just look at it and you'll
be enlightened :-)
