Cinematography is an art form in the field of filmmaking. Although the exposing of images on light-sensitive elements dates to the early 19th century,[4] motion pictures demanded a new form of photography and a new aesthetic.
On June 19, 1873, Eadweard Muybridge successfully photographed a horse named "Sallie Gardner" in fast motion using a series of 24 stereoscopic cameras. The cameras were arranged along a track parallel to the horse's, and each camera shutter was controlled by a trip wire triggered by the horse's hooves. They were 21 inches apart to cover the 20 feet taken by the horse stride, taking pictures at one thousandth of a second.[5]
Nine years later, in 1882, French scientist Étienne-Jules Marey invented a chronophotographic gun, which was capable of taking 12 consecutive frames a second, recording all the frames of the same picture. The second experimental film, Roundhay Garden Scene, filmed by Louis Le Prince on October 14, 1888 in Roundhay, Leeds, England, is the earliest surviving motion picture. The first though to design a successful apparatus was W. K. L. Dickson, working under the direction of Thomas Alva Edison, called the Kinetograph, and patented in 1891. This camera took a series of instantaneous photographs on standard Eastman Kodak photographic emulsion coated onto a transparent celluloid strip 35 mm wide. The results of this work were first shown in public in 1893, using the viewing apparatus also designed by Dickson, and called the Kinetoscope. Contained within a large box, only one person at a time looking into it through a peephole could view the movie. It was not a commercial success but in the following year, Charles Francis Jenkins and his projector, the Phantoscope made a successful audience viewing while Louis and Auguste Lumière perfected the y, an apparatus that took, printed, and projected film in Paris in December 1895.
