Ken sent me a link to this Nike swing portrait for Tiger Woods. They shot this with the Phantom v5 military-grade digital camera, capable of capturing up to 4000 frames per second. By "they" I mean Academy Award winner and frequent Steve Spielberg collaborator Janusz Kaminski, one of my favorite cinematographers.
Ken was in awe of how still Tiger holds his head. At the center of his vicious vortex of a swing, his head is the eye of the hurricane, completely at peace. I love how wide and perfect his swing arc is. The arc traced by the head of Tiger's driver is the modern version of the Vitruvian Man. From the camera in front, you can see the tee jump up in the air and twirl like helicopter blades captured in slow motion.
He's competitive as hell, but more than that, his swing is fundamentally sound.
