Simulation of a spinning zoopraxiscope An early projector and seats from a movie theater. The main precursor to the movie projector was the magic lantern.In its most common setup it had a concave mirror behind a light source to help direct as much light as possible through a painted glass picture slide and a lens, out of the lantern onto a screen.
Quite often these spools will be located some way from the projector and the film path may be over rollers along the ceiling of the projection room and surrounds. The lenses of the projector can be automatically rotated in front of the projector light aperture to accommodate the correct lens for a given format. The picture to the right shows a ...
All enlargers consist of a light source, normally an incandescent light bulb shining though a condenser or translucent screen to provide even illumination, a holder for the negative or transparency, and a specialized lens for projection, though some, such as the Rapid Rectilinear or Aplanat [citation needed] could be used in both camera and enlarger.
The first film made for the Kinetoscope, and apparently the first motion picture ever produced on photographic film in the United States, may have been shot at this time (there is an unresolved debate over whether it was made in June 1889 or November 1890); known as Monkeyshines, No. 1, it shows an employee of the lab in an apparently tongue-in ...
Overhead projector in operation during a classroom lesson. An overhead projector (often abbreviated to OHP), like a film or slide projector, uses light to project an enlarged image on a screen, allowing the view of a small document or picture to be shared with a large audience.
Projection screen in a movie theater Home theater projection screen displaying a high-definition television image. A projection screen is an installation consisting of a surface and a support structure used for displaying a projected image for the view of an audience.
In 1897, the Lumières further added to their invention by using a glass flask of water as the condenser to concentrate the light onto the film frame and to absorb heat. The flask also acted as a safety feature, as the light would no longer focus on the flammable film if the glass were to break due to overheating or accident.
Both men worked with Woodville Latham, developing a motion picture camera and projector in 1895. Dickson later acknowledged Lauste as inventor of the loop, though rival claims were made in support of another Latham associate, engineer Enoch J. Rector , who used the technology to shoot an hour-and-a-half-long documentary film , The Corbett ...
