[filmscanners] Re: Pixels and Prints



I've produced very acceptable 13x9s from a 1.68 megapixel camera, the
Canon Pro 70.

Yes, when you get up close you can see staircasing from the lack of
resolution, but in practice you don't examine big pictures close up.

And for me the complete absence of film grain makes all the difference.
