For his studies of motion, Eadweard Muybridge took advantage of great
technological advances for his studies of motion. He used gelatin-covered
“dry-plates,” which were much more sensitive to light than collodion. The
plates allowed for exposure as fast as 1/2,000th of a second. This allowed him
to prove that galloping horses do have all hooves off the ground.
