The book delves into the pioneering work of Eadweard Muybridge, an influential figure in visual studies of motion, particularly human and animal locomotion. It details his innovative photographic techniques, including his use of electric shutter releases in 1872 to capture the motion of a galloping horse, proving that all four hooves lift off the ground. The book includes the complete 781 plates from Muybridge's "Animal Locomotion" (1887) and his rare album "The Attitudes of Animals in Motion" (1881). A chronology by Stephen Herbert provides further insight into Muybridge's groundbreaking contributions to photography. Text is in English, French, and German.
