        I think there is something to this. I get better scans using
VueScan from my Minolta Scan Dual II - less noise as well as better
colour.
        On a related topic - I've recently been using the Long Pass
feature in VueScan, again with the Scan Dual II, and I'm amazed at
the reduction in shadow noise. I stopped using Long Pass with my
earlier Canon FS2710, because of a CCD overload problem which
produced bright red smears in the scans. The Minolta doesn't seem to
suffer from this problem, and I've been getting good scans from some
previously almost unusable dark slides.
