What is a Kinetoscope? The Kinetoscope was designed by Thomas Edison and William Dickson in 1891. It was designed for an individual to view the film at one time, through a window or scopes in the top of the machine. The video inside the machine is made up of a series of images on a film reel flicking through, 46 frames per second with a single bulb to illuminate and to give the illusion that the images are moving. https://www.youtube.com/watch?v=2wnOpDWSbyw
In 1892, the Kinetoscope was finalised with a minor change of the film running process, it was replaced from a horizontal spool to a vertical spool. It was unveiled and introduced to the public at the Brooklyn institute of arts and sciences in 1893. The reason for the small scope to see the images is due to the light, if too much light is introduced to the film reel, the picture will become less clear and harder to see, the darkness and the single bulb ensure that the images are as clear as possible.
