The lesson is about the movie industry of California. In 1872, the Californian railroad tyloon and racehorse breeder, Standford had an argument over whether a galloping horse ever has all four hooves off the ground. Experts and artists agreed that the hooves of horses always kept at least some contact with the ground. Standford hired an English photographer named Edward Maybridge with the intentions of capturing the truth on a photographic plate.

He emigrated to America in 1850. After coming back he set up a battery of 16 cafeterias parallel to a race track in Sacramento with each camera’s shutter connected to a wire stretched across the race track. As the horse galloped past, its legs tipped the shutters in an order, creating a series of photographs. May bridge struck the images on a rotating disc and sent a ray of a light through them.

Maybridge carried out many studies with Etienne Jules Marey, a ranch scientist who in 1882 invented a single camera. Finally he proved that all the four hooves sometimes were off the ground. Thomas Edison in 1887 invented a camera with images at 40 frames a second, to watch a film. In March 1895, a one – minute film of workers, from the Lumiere’s factories in Lyon was created. This was the evolution of motion pictures.
