ellarienAs far as I can tell, the grain on consumer-grade 35mm slide film (Agfa and Kodak, 1958-1998 or thereabouts) is roughly equivalent to 300 dpi on a 6x4 print, or a 2Mb digital camera. (I was scanning them at twice that, and you can clearly see the grains.)
The snag is that consumer-grade (or even office-grade) digital projectors can't display that many pixels properly yet; the best I've seen is 1024x768 with (I think) 8-bit color, so for projection on a big screen you still can't beat slides, even though no-one uses them any more.
