actually, the two biggest reasons film looks better both have to do with
"analog" producing LESS distortion than digital. (i put "analog" in quotes,
because the term is usually used to refer to an electrical process, such as
cassette tape or vhs, rather than a chemical/physical process.) film being
a chemical process, color resolution is quite predictable & depends on the
kind of film & the processing. years & years have gone into finding film
compositions that produce lifelike colors, whereas each video recording
head (or in the case of digital, dsp section) has to be calibrated to give
good colors. also, each frame of film is a completely separate physical
entity, & each exposure is independent of the other exposures. video
(digital or analog) is entirely electric, so each frame is subject to the
residual voltages & magnetism of the ccd & recording head. finally, film is
simply much higher resolution than even hd video. even 35mm film can give
the equivalent of thousands of dpi.
