Magic lanterns of the style were made as early as the 18th century and references to such devices can be found even earlier. The little 'nursery' magic lantern is powered by a tiny kerosene lamp and was made in Germany by E.P. (Ernst Plank Co.) probably in the 1920's or 30's. It can project a small image about 2 feet by 2 feet.
The magic lantern or Lanterna Magica was an early prototype of the modern slide projector.The basic setup is simple: There is a concave mirror behind a light source that gathers light and projects it through a slide with an image painted onto it. The light rays cross an aperture (which is an opening at the front of the apparatus), and hits a lens. The lens throws an enlarged picture of the original image from the slide onto a screen.
I like what you are posting because it's interesting to know about film history, like this things that are part of the history of film. Each of these things made what now a days it's film. They have tried many things like this one and we finally have the perfect one today.
