It was shot with a Casio Exilim EX-F1 camera at 300 frames per second then edited to 24 frames per second. Kind of the opposite of what I’ve been doing with my time lapse videos and it yields stunning results.
I really don’t need another camera….
UPDATE: Just stumbled across this post about highjacking the liveview feed over USB which comes ‘down the wire’ at 100fps…at least on the D700. So it *may* be possible with my D90 or other Nikon gear.
