| Above is Hardesty's first
setup for lighting and videotaping a slowly-turning ball for
the Was/Is piece. The turntable at top spins the ball
very smoothly at 6rpm. Problem: top of ball is pointy from weight.
|Another setup, the camera is
placed high, with turntable below. Two problems; slight jiggle,
due to direct contact with turntable. And the 45º camera
angle makes unsatisfactory turning patterns with the protruberances
on the ball.
|Third and final setup. Ball is
held in place both top AND bottom to eliminate wiggle. Camera
is moved back down to horizonal position. A variable-speed electric
drill with trigger partially depressed (with tape) is employed
to turn the ball. The drill bit is a hole saw (for drilling 2-inch
doorknob holes) with foam rubber wrapped it around for both friction
and vibration removal.
