They were also made up as strips for the popular parlour toy the zoetrope “wheel of life,” a rotating drum that induced an illusion of movement from drawn or painted pictures. The Muybridge pictures were widely published in still form. In 1877–78 an associate of Muybridge devised a system of magnetic releases to trigger an expanded battery of 24 cameras. Although posed sequential pictures had been taken as early as 1860, successive photography of actual movement was not achieved until 1877, when Eadweard Muybridge used 12 equally spaced cameras to demonstrate that at some time all four hooves of a galloping horse left the ground at once. Motion-picture photography is based on the phenomenon that the human brain will perceive an illusion of continuous movement from a succession of still images exposed at a rate above 15 frames per second. Furthermore, the technology of motion pictures is based not only on the prior invention of still photography but also on a combination of several more or less independent technologies that is, camera and projector design, film manufacture and processing, sound recording and reproduction, and lighting and light measurement. In one piece of equipment state-of-the-art digital electronics may be working in tandem with a mechanical system invented in 1895. Motion-picture technology is a curious blend of the old and the new. It includes not only the motion-picture camera and projector but also such technologies as those involved in recording sound, in editing both picture and sound, in creating special effects, and in producing animation. Motion-picture technology, the means for the production and showing of motion pictures.
