Two critical developments in photography that facilitated the creation of motion pictures were the invention of photographic film and the advancement of camera technology.
Pioneering Photographer: Eadweard Muybridge
In 1878, English photographer Eadweard Muybridge conducted a famous experiment to prove that all four hooves of a running horse leave the ground at the same time. He captured multiple photographs of horses in motion and replayed them quickly using a device he called the Zoopraxiscope. This experiment demonstrated the potential of using photography to create the illusion of movement.
Invention of Photographic Film
In 1884, New York native George Eastman invented photographic film, which allowed for the capture of images on flexible strips of paper coated with gelatin. This film made it easier to capture and preserve a sequence of images, essential for creating motion pictures.
