I recall a long time back he said he was deriving some part of his film type
correction curves or matrix data from film type data from Kodak for PhotoCDs.

Vuescan has an option to tag files with the selected color space profile (except for
Device RGB, which according to the help file "doesn't embed any ICC profile into the
TIFF or JPEG files..."). The embedded profile is recognized by Photoshop (at least it
is in my config). ProPhoto RGB is one of the color spaces Vuescan offers for file
output.
