This is some AWESOME photography, definitely going to give this a shot when I get my EPIC!
It works pretty simple, shoot with a good number of FPS and make sure you up your ISO and open up your aperture the whole way,
You'll need an pretty high shutter speed to get a cleaner freeze in the position of your choosing,
The EPIC for me would be awesome for this because 120fps means its not likely I'll miss the exact moment!
