A double exposure showing the
before and after of a shattering
paper disc. The disc, about 8
inches in diameter, is mounted
on the shaft of a motor. Motor
speed is increased until, at
about 13,000 rpm, the disc shat
ters with almost explosive force.
The noise is picked up be a mi
crophone, amplified and used to
trigger a single high-intensity
flash from a Strobotac. The photo
was taken in a darkened room to
eliminate synchronization prob
lems. Any camera having a
"bulb" or "time" shutter position
can be used. Exposure data:
Kodak Royal Pan (ASA400);
f/16; light source, a 1538 Strobo
tac and 1538-P4 Energy Storage
Capacitor.
The glide and landing of a flying squirrel captured on film with the aid of a Strobotac and
