|Format||Member Price||Non-Member Price|
In order to obtain a realistic motion picture which would completely surround the audience , a 65 mm camera was modified for 8 perforation format . A special camera lens was then designed and fabricated which images a 195 degree field as a circular image on the film . This is then projected with a 175 degree field of view projection lens ( also specifically designed for this ) . Both camera and projection lenses normally face upward . System design parameters are discussed .
