Why do they always use this weird round lens distortion thing in skateboarding videos? What is it anyway that causes that effect?
Fisheye lens
The main reason for using the fisheye is that you it gives you a view of the whole stunt.. you see the boarder coming and going. Sure, it's distorted, but the skating world long ago decided this was the preferred way of viewing skating trick. Think about shooting it head-on... you'll miss many details from any angle that you'll see underneath. But if you're shooting from under a rail or fence or something, you need the extreme wide angle of a fisheye to shoot that close to the action.
