This is exactly what a skate photographers do with one camera. Capturing a 1/1000 of a sec when the trick looks just right with one push.
I often hear that I need a "fast" camera to shoot skateboarding so that I can pic out the right frame. Skate photography is more preparations and experience than anything else.
Yes I know that this is a promotion film for Profoto, but I just felt it needed to be said that it can be done done with out a +50 000€ equipment.
