Pressing the button to take a picture is a very similar action to performing a skateboard trick. So many actions happen between popping the trick and landing it, between framing the action and having the picture. You could decompose the action into so many details : focus, pop, pressure, body position, foot movement, flick, shoulder placement, mental intention, catching the board, landing, taking impact... Just as with photography : frame, movement, focus, click, light in the lens, mirror positions, aperture, shutter speed, mental intention, sensitivity, watching the result. Both happen in one motion, but are about decomposing a movement in the search of a fragment of beauty. They are about turning a very technical process into one single organic motion, a reflection of one's mind and its ability to read space and time around it. The difference is the nature of the movement : one is mechanical, the other one is physical, so the moment when both meet should be one of chemical perfection.
