“Hexaplex” |
|
 22.06.2016Hello Thomas. I have a revision for one of the articles [previously] appearing on in70mm.com - “A Century of Widescreens at the World's Fairs” Section 18 refers to Expo 1992 - Seville / Spain. I was involved in the production of the “Hexaplex” film and can offer some additional information and corrections: The Hexaplex system was devised by Mike Browning, who had considerable experience in special format cinema systems. The film format was 35mm for both camera and projector. The camera rig consisted of 6 interlocked Arri cameras arranged to cover a full 360 degree panorama. The cameras rotated at slow speed around a vertical axis, which had the effect of moving the joins between the panels. The viewing theatre consisted of six flat screens set up to form a closed hexagon with their edges almost touching. Front projection was employed. Each projector was mounted directly opposite its respective screen and with it lens just above the top edge of the opposite screen. The projectors and screens remained fixed in position. The audience were all seated inside the hexagon on a platform which revolved at slow speed once the film had started. At this distance in time I cannot remember whether the cameras and the seats rotated in the same or opposite directions, but the effect while viewing the film was to make the joins between panels un-noticeable. Only one film was ever made in the process. Phillip Grace Cinema Technical Officer |

23.06.2016 Dear Thomas, Along with my colleague Phillip Grace, correcting the mistakes in the "HEXIPLEX" (Seville 1992) section of this article, I draw your attention the the absence of any mention of THE RAINBOW SERPENT THEATRE, the Australian government pavilion presentation at World Expo 88 in Brisbane Shot in VistaVision with a camera of my manufacture, this complex presentation featured a rock cave with a live actor and two 70MM interlocked projectors. The front projector beamed images by Pepper's Ghost into the cave while the rear projector displayed a changing landscape beyond the stage, reflected in black glass. The 6 track sound was magnetic from the front projector. The Actor mimed the narration and synchronised his actions with the film images, unseen by him. At the end of the show he disappears behind his exploding campfire and a giant snake takes his place, whirls around the stage and flies from the cave into the hills as they transform from desert landscape to lush green with emerging lakes... A very complex, wonderful 70MM show Regards Bruce McNaughton The Aranda Group Melbourne |
