#Film projektor movie
The first available film used in commercial movie projection was nitrate, a transparent, plasticized film base. Projection booth with three 1936 Ernemann VII projectors (top), and with a single Phillips FP30 projector and non-rewind platters (bottom). “We weren’t certified technicians so we weren’t surgeons, but we had to know enough to apply first aid and that encompassed the film itself, the mechanics of the projectors, the electronics of the lamps, the mechanics of the platters, the sound systems, any one of those items could fail.”īeing a projectionist was a dangerous and difficult job before innovations made projection safer and automated. We were EMTs, if you will, in the projection booth,” says Rivierzo. “Anything could go wrong and we were responsible for the maintenance and the first aid. Multiplexes were uncommon, fires arose, and equipment often malfunctioned. Before the era of digital projection, “it was a labor intensive job,” says Joe Rivierzo, a third generation projectionist and executive board member of the New York City projectionist Local 306.
What about the work of the people behind the magic, upstairs in the projection booth? When it comes to 35mm film, it’s not as simple as just pressing play. The continuous succession of the frames causes our brains to connect each image and they seem to move. Each frame pauses for a fraction of a second in front of the lamp and lens assembly.Here, the film is illuminated and projected onto the screen through a lens. Film, which is made up of single images, or frames, moves continuously along a feed disc, operated by an electric motor.
Movie projection works because our brains retain an image for slightly longer, one twenty-fifth of a second to be exact, than we actually see it. But how much do we really know about this popular pastime? Whether it’s for a panic-inducing horror film or sci-fi adventure, we’ve all been to the cinema.
