Tony, Thanks. In comparing the SS400 scan results between Vuescan and the old Polaroid Polacolor Insight, I find Vuescan seems to give a sharper scan but produced a scan terribly biased toward blue. It just takes me forever to correct the colors with Vuescan.
Even using the grey balance dropper, I still don't get colors true to the scanned transparency. In Vuescan, what do you use for the "scanner profile"? I have been using the "built-in." In fact, I would love to see what settings you typically use for Vuescan on your SS4000 when scanning Velvia. Maybe you could send me an .ini file.
