I think Matthew is right on target with his thoughts there.
I'll add that one of the things that brought me back to film is the notion of "authenticity".
I'll grant that it is entirely possible to create, using purely digital photography, just about any "look" that can be created in the analog world. And even if you can't get 100% of the way there, you can get 99.9%.
But even if you do, you are creating a simulation of something else. Why create that when you can create something authentically real?
That's what I'm in it for.
