persistent of vision the phenomenon whereby the eye remembers what it has just seen after the object has disappeared in film and video this phenomenon is wiely believed to account for our ability to perceive a sequence of frames as a continuous moving picture in 1500 Leonardo da Vinci gave us a full description of the camera obscuro an optical device that projects an image of its surroundings on a screen Leonardo da Vinci was well ahead of his time Leonardo's writings and notes long remain in manuscripts shortly after his death those passenges from his papers dealing with painting were combined into the trato de Laura this is where we find the Vin's desire for painting to be a living thing in 15 15 the Vinci presented a drawing of a type of image projector the Magic Lantern which was later developed in the 17th century In 1832 Joseph Plateau introduced the phenakistoscope pictures on one disc viewed through slots on the other appeared to move when the two were spun and viewed in a mirror the zeotrope was introduced by William George Herer the zeotrope used the same Principle as plateau's Fisto scope but instead of discs the pictures and slot are combined in a rotating drum in 1877 Emil Renard introduces the latest findings on optical reproduction of movement the praxinoscope similar to the zeotrope the illusion of movement produced by the praxinoscope was view on mirrors in the center of the drum rather than through the slot on the outside in 1872 Leland Stanford the governor of California insisted that a horse in full stride takes all four feet off the ground Stanford hired Edward mbridge a San Francisco photographer to prove his point and set a $25,000 bet after many unsuccessful experiments mybridge mounted a line of cameras alongside the racetrack and tripped the shutters with electromagnets As A Horse and Rider galloped down the racetrack and over a short hurdle the pictures pro that a horse does indeed take all four hubs off the ground while Galloping mybridge developed a projector to present his findings he adapted horn Z Thro to produce a zoo praxinoscope in East Orange New Jersey Thomas Edison was pridefully working on perfecting his favorite of all his inventions the phonograph Edison assigned William Dixon to the project of developing a machine that could visually accompany his phonograph for over 2 years not much resulted they finally designed a machine the mutoscope that they thought might work but what were the pictures to be on in 1888 George Eastman devised a flexible film based covered with photographic and motion this was was exactly what Edison and Dixon were looking for the result the ketos scope the kinoscope is a continuous loop of film that passed over a series of rollers and in front of a lens but it had a flaw it allowed only one person at a time to watch the moving images being put on display Thomas armad found that what the camera did to hold a film stationary while the images were being photographed could be repeated in a projection mechanism itself in 18 85 in Atlanta Georgia armad made a vital connection he demonstrated a projector that worked the lamir family is the biggest manufacturer of photographic plates in Europe a local kinoscope exhibitor asked Brothers LS and Augusta lir to make films which are cheaper than the ones sold by Edison Louis and Augusta designed a cinematograph a camera which serves as both a recording device and a projecting device the cinematograph uses flexible film cut into 35 mm white strips and used an intermittent mechanism modeled on the sewing [Music] machine the camera shot film at 16 frames per second rather than the 46 which Edison used this became the standard film raid for nearly 25 years the arrival of a train is considered by most to be the first motion picture presented to a large public audience this cinematic experiment demonstrated the Lam's new invention the cinematograph which captured a train arriving at a passenger station the audience were startled and started to panic as the train moved towards them so who invented film while film itself was invented by George Eastman the motion picture was an invention of many inventors it was all just a matter of putting the pieces together
