Hi
I'm Don L.
I am a master at hand held DV. Here are my secrets...
1.) Buy the book "Setting Up Your Shots"
Even though it's a book on camera shots for 35mm you can go through it and imitate the more simpler shots and use it for a DV hand held style.
2.) Watch the movie "The Celebration" and "Running Time" - "Running Time" was one continuous shot. From TV you can watch "The Shield"
Have Fun
