RE: filmscanners: High End Scanner Prices
I was under the impression that the Minolta only interpolated in one
direction, so it creates "rectangular" pixels. So a 6x7 image could be 7,559
by 13,228 pixels. To produce "square" pixels, you would have to interpolate
only in one direction, 7,559 to 11,339. That would give a 900 megabyte file
at 16 bits, a tough one to edit. If you just scanned at 3200 ppi you would
end up with a 7,559 by 8,819 pixel image that is 400 megabytes. Is that big
enough? I guess it depends on what you are going to do with it.

Yes, but the Minolta is 4800 dpi *interpolated* for medium format.
it's a neat trick to make the numbers look good.
the Nikon and Polaroid remain tops at 4000 dpi for MF.
