A couple of years ago my friend, Chris Archer, talked to me about a project he wanted to do. He'd just bought a Sony F55 Cine Alta video camera that was capable of shooting pretty decent slow motion and he had a friend who was an accomplished dancer. He wanted to shoot her in front of a wall of cascading sand as she dropped into the frame from above, and he wanted everything but the sand and the dancer to drop into total black.
During the course of his experimentations he decided that he really needed to shoot with a Phantom camera for even slower, slow motion. He also decided that he needed to build this rig to drop the sand evenly across two, large intersecting planes. Chris had carpenters build the entire rig/set for this in an airplane hangar at the old, Mueller Airport, here in Austin.
Chris asked me to help out with the lighting. We wanted a semi-hard source that was somewhat directional but had soft edges. I figured a 24 by 36 inch, heat proof softbox with a 2,000 watt, open face tungsten light would be good. I skirted the box with black fabric to cut down on spilling light so we didn't contaminate the background of black felt. We were able to pull f2.8 at our high speed settings something like 600 frames per second. With the fast, Zeiss cine lenses we were using that aperture was the perfect combination of sharpness and depth of field control (sharp subject, sharp sand, not sharp black material). We added a few highly controlled spots for fill in light but they had little overall effect on the scene. I could tell they were there but they were subtle...
Once Chris had his angles figured out we started placing the two thousand pounds of sand on the set.
The resulting video was pretty amazing. It takes eight or ten seconds from the point the dancer enters the frame until she lands on the sand. Every grain of sand that puffs up is clearly delineated. I liked the concept. I loved the fact that Chris was so committed that he engineered every piece of a custom set that took weeks to concept, design and implement. Sometimes that dedication to doing things exactly right goes missing when clients show up with budget restrictions and a general lack of understanding just how much goes on
