The 59th Pula Film Festival held in the ancient Vespasian's Amphitheatre which dates back to the 1st Century recently set a Guinness World Record for the largest audience ever for an outdoor 3D film presentation. The event will be remembered as an industry first in three categories: the 3D projection setup achieved the longest throw distance (using a Barco DP2K-32B projector) ever recorded at 73.6 meters (242 feet) exceeding the recommended throw distance; the setup which included an 18.70 x 8.45 meters Stagelite Stereo 3D Screen from Harkness Screens achieved a wide-viewing angle of 60 degrees allowing the 3D presentation to be viewed at suitable brightness levels throughout the entire seating area; as a result the film festival was able to set what is believed to be a new Guinness World Record for an outdoor 3D presentation with an official attendance of 5 920 visitors. “We were delighted to supply the Stagelite Stereo surface for the festival and provide installation support. The setup achieved by Laboratory of Multimedia Technologies in Zagreb the festival’s technical resource was nothing short of remarkable and they deserve much praise ” said Tony Dilley European sales manager at Harkness Screens. Stagelite Stereo is a front projection surface specifically designed for non-cinema 3D applications. Silver aluminium flake based PVC fixed to a unique base material provides high gain characteristics very low depolarisation level (extinction ratio) and excellent color temperature. The surface type also supports conventional 2D pictures and is also cleanable.
