I do believe that Wizi is acting more or less
"sensibly" and that I'm using it right.

Your suggestion about letting the print dry is
a good one... I'll try again.

I know it's important to keep the scanner settings
dead-flat neutral, with "auto" color correction turned
off.  But what about the gamma or brightness setting
on the scanner?  Might that affect the very darkest
tones in the scanned image that Wizi analyzes?

I know these are all supposed to come out in the
wash, but if all of the dark patches yield figures
close to zero, then I can see where Wizi is going 
mess up.

I'm really not interested in the scanner profile
itself, and have no plans to use the Wizi-generated
scanner profile.
