Would it be possible to modify an Epson scanner to get higher-res?

I never quite understood the aliasing nomenclature, wouldn't that imply a byproduct like a moire from a 2 source interference? Effect on grain from drum scanner always seemed to me more related to callier effect. Tim Vitali's paper remains one of the best on the subjet, o matter the terminology. Have I confused things any?

There "used" to be a few mid-price flatbed film-capable scanners that were a step-up from the Epson, but alas with the contracting film market, they went away. With that said, scanning is an "art" and a "skill" and I have seen stunning scans from Epson scanners by those who are very good at scanning. You don't always have to have the highest optical resolution for a big print, with interpolation, it all depends on the subject matter, and your scanning skill and post-scanning file work in Photoshop.

Tyler, I agree in that I always thought aliasing involved some sort of interference phenomena. But maybe the term is used to cite more general cases beyond the simple mathematical case of interference.

BTW, do you have a reference for the Tim Vitali paper handy?

I never saw any decent scan from an Epson scanner, even from the best operators (like me)
