Film and Video
Pritchard began his film and video
work in the mid 70's by building a motion control system for a film
studio. This system was designed to artistically give motion (pans,
tilts, and zooms) to various types of flat art and transparencies.
This project began with design discussions that sought out the client’s
operational desires. The natural give and take of creative people produced
a very unique and powerful system.
The electronics for this system was
redone in the late 80's to enhance system capabilities and to replace
aging electronics. This system, dubbed Animotion, is still in use today.
This project led to a study of stepping
motor resonance and non-resonant drivers. A computer control system,
Athena 11, was
designed around these new drivers. The computer control systems were
installed on various camera systems, some designed and built by Metis.
One of these computer controlled
systems employed two video cameras set on separate stages for a total
of 12 axes. The computer could control the two cameras and their stages
separately or together. The unison operation was used to video the foreground
and background for later mixing.
Pritchard and Metis consulted on,
designed, and built a variety of prototypes for a three-dimensional
photographic technique. This work resulted in several
U.S. Patents and many more
foreign patents.
Metis has also modified a variety
of film cameras
for automated photo duplicating processes. These were actually movie
cameras and used large film magazines. The camera modification changed
the format to still dimensions and provided control for filming with
much slower, higher resolution films.
Metis has also built
Special Effects Systems, such as a digitally controlled panning
system for the South Street Experience. The digital panning system
panned a projector from side to side of a screen to give the narrator
some additional animation and to give the show’s designer, Rusty Russell,
some additional artistic freedom.
