I just feel like filming any action sport is to easy of a " career " it doesn't really take talent you just follow a guy in the air til he lands. Fill it with b footage of trees and nature and shit for skiing or snowboarding, if it is bmx or skating fill it with streets and city life you have an edit. The only thing these " filmers " have going for them is that their mommy and daddy bought them the best equipment (splice) so they can get the best pretty shots. Anyone can make edits it doesn't take much, just a lot of money to spend on the best equipment. As far as talent goes you don't need any as long as the shots are super digital hd.
