Opaque Projectors (Episcope) and Megascope: the precursors of film and movie



Opaque projectors, also known as episcopes, were invented in the late 18th century and were used to project still images onto a screen. The first version demonstrtad Leonhart Euler in 1756. These images were usually taken from photographs or illustrations and were often used in educational settings. The device itself consisted of a box that contained a light source and a lens system. The image was placed on a glass plate inside the box and the light from the source was projected through the lens system onto a screen.


A megascope, on the other hand, was a more advanced version of the opaque projector. French scientist Jasques Charles used for lectures in 1780. It was invented around the turn of the 19th century and was capable of projecting moving images. This was achieved by using a series of still images that were rapidly projected one after the other, creating the illusion of movement. The megascope was often used for entertainment purposes, such as showing short films or cartoons.



Despite the advancements made by these early devices, they were still limited in terms of the quality of the images they could produce. It was not until the invention of the motion picture camera and the development of celluloid film that the entertainment industry truly began to take off.

Despite this, opaque projectors and megascopes played an important role in the development of the entertainment industry. They paved the way for the technology that we have today and allowed people to experience moving images for the first time. Today, these early devices are often considered to be important pieces of history, and can be found in museums and collections around the world.



In conclusion, opaque projectors and megascopes were precursors to modern film and movie technology, played an important role in the development of the entertainment industry and although limited in terms of the quality of the images they could produce, they were a stepping stone for the technology we have today.

Chronophotography 1882-1890 - early film technology

Image
. Chronophotography, also known as time-sequence photography, is a type of photography that records a series of images over a period of time to analyze and understand movement. The development of chronophotography was an important milestone in the history of photography and film technology. Between 1882 and 1890, a number of prominent photographers and scientists made significant contributions to the field, including Eadweard Muybridge, Albert Londe, Étienne-Jules Marey, Georges Demeny, and Ottomar Anschutz. Eadweard Muybridge , an English photographer, is considered one of the pioneers of chronophotography. In 1872, he was commissioned by Leland Stanford, a wealthy businessman, to prove that a horse lifts all four hooves off the ground during a gallop. Muybridge used a series of cameras placed along a racetrack to capture images of the horse in motion, which he later combined into a sequence to demonstrate the horse's movement. This was one of the first recorded uses of chronophot...

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 Phenakistoscope: The Forgotten Device that Paved the Way for Motion Pictures

Image
The Phenakistoscope, an early optical device invented by Joseph Plateau in 1832, is often overlooked in the history of cinema. However, this device, which used the principle of persistence of vision to create the illusion of motion, played a crucial role in the development of the motion picture. The Phenakistoscope consisted of a spinning disc with images drawn on it, which were viewed through a series of slits as the disc spun. As the viewer looked through the slits, the images on the disc appeared to move, creating the illusion of motion. This device was a significant improvement over earlier optical devices such as the zoetrope, which only created the illusion of motion when viewed through a small opening. The Phenakistoscope, on the other hand, allowed for the projection of moving images, making it more similar to modern motion pictures. The Phenakistoscope was widely popular in the 19th century, and it was used for entertainment and education purposes. It was considered to be one ...
