One does not have to anything in post to get a "film look" when shooting film.
But, sorry, post has been a pretty important part of the filmmaking process since the advent of telecine and DI. Even if you hand over your film to your clients (as all commercial DP's do) they are going to drastically alter it in post.
And I did say "In shooting and in post", by the way. The EX1 has many settings to allow you to "paint" in camera, if you want to limit your post options that way.
Different conversation altogether, so I won't start that one. Everyone knows post has been a MAJOR part of filmmaking. Nobody's denying that. But the do-it-in-post mantra's usually not what people coming from film think.
Anyway. This thread needs to be closed. The poster has decided, no need to keep goin.
