When you sit in front of a movie theater's projection screen, watching the screens, plots and characters played, do you know how the movie was invented? How did the screen of the movie come from? The advent of
movie originated from a gambling contract. In 1872, several British horse racers argued over whether a hoof always touched the ground when the horse ran, and made a bet about it. In order to understand the reason, McBridge placed 24 cameras on the side of the road. When the horse ran in front of the cameras, he took pictures of the horse's movement. Then, he placed the photos on a rotatable glass disc in turn, and used a disc with a notch to do the reverse movement, so that the photo wheel flows out of the notch, so that a set of continuous motion images of the horse running . This is the embryonic form of film, and it laid the foundation for future generations to study film. After
, the French scientist Marais, after inspecting McBridge’s equipment, came up with the idea of inventing a machine that can shoot continuous actions. After a long period of research and development, a series of continuous pictures were finally taken in 1882 at a speed of 12 frames per second. When Marley applied for a patent, he referred to this device as a "movie." Since then, this name has spread and is still in use today.
In fact, the time when the real film was recognized as being appeared on December 28, 1895, was filmed by the "event projector" invented by the French photographers Louis Lumiere and Auguste Lumiere brothers. They set up the machine they invented in a cafe and showed several sets of photos of their activities in front of the public. People were shocked when they saw moving images of babies drinking soup and trains on the white screen, so they set this day as the day of the invention of the movie. This is how
movies appear, and there are probably two theories about the principles of movies. The first is to explain the persistence of human vision. The so-called persistence of vision refers to the photoreceptor cells on the retina when people watch bright scenes. When the light stimulation disappears, the image on the retina will not disappear immediately. This statement is based on the phenomenon of persistence of vision. It is believed that after the first frame is removed, the image formed on our retina has not disappeared, and the second frame (the movement of the object is slightly displaced from the previous frame) comes again In this way, connecting the images that gradually change the action for us to watch, it is regarded as activity. Another way of thinking is to use people’s psychological effects to explain the principle of movie activity. It is believed that when people watch movies, they can feel the effects of activity. This is based on people’s accumulated experience of “movement” in daily life, and through psychological Caused by the association. This is how the
film's development process and principle of activity are, do you understand?
