Talking tech, IMO, is a pointless battle in a digital vs film discussion. For me the debate is mostly emotional.
The assumption in most of those debates seems to be that the same result is expected and that the same process (mine of course because I'm right ) will work for everyone.
Heck, in the real world it's tough to get landscape and portrait shooters on the same page about choosing exposure. Slide shooters and negative shooters see things differently. Pictorialist's vs f/64, journalistic vs posed style. Hurrell vs HCB.
To that end I'll answer; "Because I find using film fun and it helps me think differently about my shots and I don't want my photos to be like everybody else's."
