RE: filmscanners: 35mm filmscanner choice

["Jawed Ashraf" <Jawed@cupidity.force9.co.uk>]

A comparison of the LS4000 and some Imacon, a while back, seemed to indicate
that the LS4000 has resolution roughly equal to the Imacon's 3200dpi (some
parts of a test image were better, others worse).

Does anyone have a thorough understanding of this?  Have I got the wrong end
of the stick?

Can someone explain how to go from ppi to lpi?
