The Théâtre Optique (Optical Theatre) is an animated moving picture system invented by Émile Reynaud and patented in 1888. From 28 October 1892 to March 1900 Reynaud gave over 12,800 shows to a total of over 500,000 visitors at the Musée Grévin in Paris. His Pantomimes Lumineuses series of animated films include Pauvre Pierrot and Autour d'une cabine. . (...) Wikipedia
The collodion process is an early photographic process. The collodion process, mostly synonymous with the "collodion wet plate process", requires the photographic material to be coated, sensitized, exposed and developed within the span of about fifteen minutes, necessitating a portable darkroom for use in the field. Collodion is normally used in its wet form, but can also be used in humid ("preserved") or dry form, at the cost of greatly increased exposure time. (...) Wikipedia
Halftone is the reprographic technique that simulates continuous-tone imagery through the use of dots, varying either in size or in spacing, thus generating a gradient-like effect. "Halftone" can also be used to refer specifically to the image that is produced by this process. (...) Wikipedia
The gelatin silver process is the photographic process used with currently available black-and-white films and printing papers. A suspension of silver salts in gelatin is coated onto a support such as glass, flexible plastic or film, baryta paper, or resin-coated paper. These light-sensitive materials are stable under normal keeping conditions and are able to be exposed and processed even many years after their manufacture. This is in contrast to the collodion wet-plate process dominant from the 1850s–1880s, which had to be exposed and developed immediately after coating. (...) Wikipedia
Berliner Gramophone – its discs identified with an etched-in "E. Berliner's Gramophone" as the logo – was the first (and for nearly ten years the only) disc record label in the world. Its records were played on Emile Berliner's invention, the Gramophone, which competed with the wax cylinder–playing phonographs that were more common in the 1890s. (...) Wikipedia
