What every one has already stated is really great advice.

But here is a piece of advice from my personal experience with filming hunts and perhaps the hardest to teach.. TELL A STORY. Don't be afraid to use LOTS and LOTS of tape. Go out there and film, film, film! But don't forget to TELL a story. It really will disappoint you if your footage looks all "cut up".. really try to put a full story together by filming everything involved with the hunt. The "intimacy" of the hunt if you will.
