How did cinema develop?
In the 1870s, Leland Stanford laid a guess on whether or not all 4 ft of a galloping horse have been ever off the floor on the equal time. He hired a British photographer Eadweard Muybridge who photographed a shifting horse on 12 cameras. The pictures confirmed the horse with all 4 toes off the floor. In 1889, George Eastman added the celluloid roll. Celluloid, a cloth crafted from the chemical substances camphor and nitrocellulose, become used as a medium for film photography.
