Motion Picture
Edison’s original work in stir filmland( 1888- 89) was inspired by Muybridge’s analysis of stir. The first Edison device recalled his phonograph, with a helical arrangement of 1/16 inch photos made on a cylinder. Viewed with a microscope, these first stir film land were rather crude, and hard to concentrate. Working with W.K.L. Dickson, Edison also developed the Strip Kinetograph, using George Eastman’s bettered 35 mm celluloid film. Cut into nonstop strips and perforated along the edges, the film was moved by sprockets in a stop-and-go stir behind the shutter.
In Edison’s movie plant, technically known as a Kinetographic Theater, but nicknamed “ The Black Maria ”( 1893), Edison and his staff mugged short pictures for latterly viewing with his glance hole Kinetoscope( 1894). One- person at a time could view the pictures in the Kinetoscope. There has been some argument about how important Edison himself contributed to the invention of the stir picture camera. While Edison seems to have conceived the idea and initiated the trials, Dickson supposedly performed the bulk of the trial, leading most ultramodern scholars to assign Dickson with the major credit for turning the conception into a practical reality. The Edison laboratory, however, worked as a cooperative association.
