Steganographic Mirror: The Precursors of Film and Movie

Image
The history of film and movie technology is often thought to begin with the invention of motion picture cameras and projectors in the late 19th century. However, there were several precursors to these devices that utilized similar principles of capturing and displaying moving images. One of the most interesting and lesser-known of these precursors is the steganographic mirror. A steganographic mirror is a device that uses a mirror to reflect an image onto a surface, such as a wall or canvas. The image is created by using a series of small, rapidly moving parts, such as a spinning disk or a rotating cylinder, that are placed in front of the mirror. These parts are typically adorned with small images or designs that, when viewed through the mirror, appear to be in motion. In 1645, Athanasius Kircher , a German Jesuit scholar, included a description of the steganographic mirror in his book Ars Magna Lucis et Umbrae . The device was a primitive projection system that used a concave mirror ...

Electrotachyscope, Elektrischen Schnellseher, literally "Electrical Quick-Viewer" - early film technology

Image
The Electrotachyscope, also known as the Elektrischen Schnellseher, was a revolutionary piece of early film technology developed by German inventor Ottomar Anschütz in the late 19th century. The name "Electrotachyscope" translates to "Electrical Quick-Viewer" in English, and it was designed to allow for the rapid viewing of short films. Anschütz was a prolific inventor, with a wide range of interests that included photography, optics, and electrical engineering. In the late 1870s, he began experimenting with a device that would allow for the rapid viewing of short films, and he eventually developed the Electrotachyscope. The Electrotachyscope was a hand-cranked device that used a series of lenses and mirrors to project moving images onto a screen. The images were created by a spinning disc that had a series of sequential photographs mounted on it. As the disc spun, the viewer would crank the handle, and the images would appear to come to life in a rapid sequence, gi...

The Kinematoscope (a.k.a. Motoscope) 1861 - precursors of film and movie

Image
The Kinematoscope was a revolutionary device that was invented by Coleman Sellers II in 1861. It was one of the first devices to successfully bring the illusion of motion to life, marking a major milestone in the evolution of motion pictures. The Kinematoscope utilized a series of still stereographic images that were mounted on blades of a spinning paddle. These images were viewed through slits in the device, which were positioned in front of a stereoscopic viewer. The result was a unique viewing experience in which the pictures appeared to move, even though they were not projected onto a screen. Instead, they were visible within a cabinet. The Kinematoscope was widely popular and was used for both entertainment and educational purposes. It was a critical step forward in the development of motion picture technology and paved the way for the creation of motion picture cameras and projectors. The Kinematoscope was not only an entertainment device, but also an educational tool that was us...
