/Agrees with Sable & Myelin. Shooting film teaches you to gauge what's important and what's not. Your first few rolls might turn out like crap, but you'll learn
very quickly what works and what doesn't - either that or you'll go broke.
Shot properly super 8 rivals standard definition video (including MiniDV) in terms of resolution. It produces a unique look, richer colours and gives you superior exposure latitude when compared to video, especially if you shoot negative stock.
The question is what do you want to do with your footage. Do you want something artistic and unique, or do you want the equivalent of home video footage? I have super 8, 16mm and MiniDV equipment and use all of it for different things.
Shoot some test rolls and get them developped. See what you think. If you have a local film cooperative talk to them, someone there will probably know about super 8.
www.filmshooting.com is also a great place for information and advice.
Good luck!
