Portable Multi-Media Rear-Screen Presentations
Roy C. Follett · Journal of the SMPTE · 1973
A portable multi-media rear-screen presentation was created for promotional purposes and has been shown to potential customers at luncheons serving about 250 guests. A 74- by 14-ft (22.5- by 4.3-m) rear-projection screen was constructed, to display 14 images of different sizes and shapes, projected by 16 Carousel slide projectors and one 16mm arc projector. The 14-minute presentation was programed on four Spindler & Sauppe Quadra Ques, used in tandem with a 4-track TEAC stereo tape unit. Three Spindler dissolve units and a variety of short focal length lenses were used. A special portable scaffolding was built to hold the series of projection units. The equipment was transported throughout the United States in a Dodge van and was set up in six hours by two projectionists.
