stereo 3-D camera rig, one might
cause the centered object to shift to
the left, while the other lens shifts it
to the right, or any combination of
misalignments ultimately detracting
from the 3-D illusion. Proper alignment and centering at every focal
point must be set at the factory.
Stereo 3-D lenses are also configured to allow for automation, such
as a Synchronous Control box that
can synchronize the operation of two
lenses in tandem, automatically. If the
user needs to know the precise lens
position in order to accurately repeat
a shot, that information is available as
an output. With a RS-232 port on the
Synchronous Control box, this system
now allows operators to adapt any
brand of serial controller they like.
There are also instances where stereo 3-D camera rigs are mounted on

jimmy jibs or cranes, or positioned in
hazardous locations, such as alongside
a racetrack to capture a high-speed
race. By adding a wireless controller, all
cable connections are eliminated, such
as those running from the hand control up to the 3-D camera rig atop the
crane. Operators can then control the
lenses from a distance of up to 100m
away, including from inside a nearby

In the future, expect to see increased
demand for stereo 3-D lenses, especially
for events like the Olympics and World
Cup. Stereo 3-D is also proving especially beneficial to such sports as boxing and on golf putting greens, where
the action is confined to a relatively
small area. During the 2011 Masters
Golf tournament, there were more than
20 3-D camera rigs with lenses on the
greens, enabling viewers to detect how
the contours of the course might affect
the way the ball would travel. BE
