Obviously, doing one's own tests are the best way to learn. The next best, and much cheaper, option is watching others' work and trying to figure out what was done.
And one can't do that figuring out without knowing exactly which format (or formats) the production was shot on. And this means more detail than just "35mm" or "HD". Which stock? Which camera? Which lenses?
IMDb can be very hit-and-miss in this regard. I'm currently trying to find out info about the NBC series "Heroes". Everyone here agrees it's very well shot. Yes, but on what!?!? :)
So, if anyone knows a Web site that has good reference info like this, let me know. K'noath, I'm even willing to spare a few bob to join one.
