Hi, John,
Thanks for the kind words about my approach. I spent a fair amount of
time picking Sue Bigelow's brain. She is the digital conservator for the
CIty of Vancouver (BC) Archives and attended one of my tape restoration
seminars. We've talked to each other many times about a wide variety of
preservation/digitization issues.
Perhaps the best advice Sue gave me was to study some of Tim Vitale's
papers as they provide insight into the capabilities of film-lens
combinations. My decisions were based on a compromise of the original
film quality, the subject/technique of broad categories of originals,
the potential use of some of the images, and the pure math behind it. At
one point, I shot a bunch of Ektachrome 400 intermixed with a heap of
Kodachrome 25. Obviously, those were separated out and we had different
scanner presets for each.

and there are some others
