I sent that reply to someone on another list who was using large-format film
but then scanning it at one-quarter of the optical resolution of his scanner
since he didn't want large files. There was some doubt as to whether I was
correct, so I thought I would see what this filmscanners list
I believe what Bob is stating is that some scanners literally skip lines
or sensors and just record the spaced information, rather than taking
the full resolution and then averaging the pixels out via a series of
algorithms. This, of course, would introduce a great many sampling
errors, since it i

Thanks, that clarifies things a great deal.
