Muybridge motion study camera. This is one of the cameras used by the English photographer Eadweard J. Muybridge (1830-1904) in his pioneering work documenting the motion of animals. The camera is at left and in front of it is an electroshutter seen from the side (and seen from behind at right). The most famous example of Muybridge's work was his study of a horse galloping, carried out in 1878 and 1879, in Paulo Alto, California, USA. This photograph is from Muybridge's book The Attitudes of Animals in Motion (1881).
