1. Visual retention "makes a piece of burning charcoal turn into a ribbon of fire when it is waved. This phenomenon has been discovered by people in ancient times." However, compare this visual phenomenon with the film's The invention was connected, but it was a matter of the 19th century. In 1829, the famous Belgian physicist Joseph Plato once stared into the strong sunlight for a long time in order to further examine the limit of human eyesight's light tolerance and the retention time of objects. As a result, he became blind. But he found that the shadow of the sun was deeply imprinted on his eyes. He finally discovered the principle of "visual retention". That is: when the object in front of people's eyes is removed, the image of the object reflected on the retina will not disappear immediately, but will continue to stay for a short period of time. Experiments have shown that the retention time of objects is generally 0.1-0.4 seconds. At the same time, in European physics textbooks and physics laboratories, the principle of "Faraday's wheel" and the visual study of the rotation of the "phantom disk" in pictures also began to be used. They show humans that the physiological function of human vision can combine a series of independent pictures into a continuous movement of vision. In the 1830s, visual toys such as trick boards, horse racing boards, wheel wheels, movable mirrors and strobe observers appeared one after another. The basic principle is similar, that is, a series of images are drawn on a movable optical disc that can rotate, and when the optical disc rotates, those dull, lifeless images will move and come alive. After that, the Austrians combined the slide show with the movable video disk to project the static pictures on the screen to create a movable slide show, forming early animation. However, by the 1960s, film theorists and educators raised new doubts about the problem of "visual retention". They found that all movement phenomena on the screen were actually jumpy and incoherent, but the audience was aware that It is a unified, complete sequence of actions. This proves that what really works is not "visual retention", but "psychological recognition". 2. Photography Photography also emerged in Europe in the 19th century when Kang Yong's culture spread. In 1839, the Frenchman Daguerre based on the principle of imaging small holes in paintings after the Renaissance and used chemical methods to permanently fix the image. The "Daguerreotype" was born. In front of consciousness, it is no longer possible to be satisfied with static, exquisite, single photos, but to dream of one day being able to connect them to each other and faithfully replicate the physical realization of image movement and natural space. In 1872, photographer Edward Muebridge was the first to apply "photography" to continuous shooting. Over the course of five years, he experimented with using multiple cameras to continuously photograph a running horse, and succeeded in 1878. This talented photographer lined up 24 cameras in a row. When the horse ran by, the shutter of the camera was opened, and the horse's hooves and the momentary posture of the horse were photographed in sequence. To this end, Edward? 6? 1 Bridge obtained the patent for "Methods and Devices for Photographing Moving Objects." In 1882, the Frenchman Marais used the intermittent principle of a revolver to develop a "photographic gun" that could take continuous shots. After that, he invented the "film continuous camera". Finally, a video camera began to replace Mumbridge's method of photographing moving objects with a group of cameras. In Europe, during this period, scientists and inventors in many countries also developed different types of cameras. Among them, the American Thomas Edison and his mechanic Dick invented the traction method of drilling holes on both sides of the film in order to make the film move at the same intervals in the camera, which solved the technical problem of mechanical transmission. The "photography" of "event photography" was completed. 3. Projection In 1888, the Frenchman Emile Reno invented the "optical movie camera", and people began to be able to see moving movies for a few minutes on the screen, such as "Poor Bié". When the Lumière brothers showed the public the scene of "A Train Arrives at the Station" in 1895, the audience was frightened and frightened by the almost living image.
Since then, the cinematogrphy initiated by them has not only shown epoch-making significance in the history of the development of human documentary tools, but the footage of the train entering the station also symbolizes the origin of the development of film technology. Modern movie projection Super large screen movie: using 70mm movie projection technology, it is called super large because of its huge screen. The screen height is 21 meters and the width is 30 meters, which is equivalent to the height of a seven-story building. The screen is so big that it is rare in the world. It has the characteristics of stable and clear picture, normal color restoration, etc. The real and magnificent scenery on the screen gives people a sense of beauty and movement. As the far and near lenses are pushed and pulled, it will bring you into an exotic and beautiful world. In nature. Dynamic dome movie in the dome theater: The hall uses 70mm projection equipment, and the hemispherical screen has a diameter of 18 meters. When the audience watches the movie, the entire screen is covered with spheres, ignoring the edges of the screen. The transmissive metal screen, six-sound The stereo sound effect enables the audience to enjoy the ever-changing and lifelike scenes. The dynamic platform in the theater is a high-tech system engineering that integrates hydraulic pressure, electrical automation control, and computer animation. When you sit on the platform carrier, the entire carrier can rise and fall, tilt left and right, and pitch forward and backward, simulating aerospace. The vehicle invites you to travel into space, or you can simulate a submersible to enjoy the strange scenes of the underwater world. With the realistic pictures and the activities of the platform carrier, people can't help but enter the role, creating a very real and thrilling water screen movie. Special feeling, dome dynamic movies fill the domestic gap. Water curtain movie: completely different from a conventional movie. It uses a high-pressure water pump to spray water from bottom to top through a special nozzle to atomize the water and form a fan-shaped screen. This screen is connected with the night sky in nature. Characters enter and leave the screen, suddenly take off to the sky, and sometimes fall from the sky, creating an illusory and ethereal feeling, like a mirage. At present, water curtain movies are still rare in our country. Ring-screen movie Ring-screen movie: Ring-screen movie is also called a 360-degree circle movie. The circular hall is surrounded by nine screens to form a ring screen, which is projected by nine projectors at the same time. When watching, the audience stands in the center of the circle. Looking forward and backward, looking left and right, you will be dazzled by the spectacular scenes and majestic momentum. Coupled with the multi-channel stereo effect, a strong and immersive feeling will be presented in front of you. 3D movie 3D movie: It is a unique spatial image and three-dimensional effect produced by the combination of optical principles and the parallax of the human eye. When you wear special polarized glasses, you will feel that everything on the screen is the same as nature. There are different distances, far and near, front and back, some scenery is so close in front of you, it seems that you can easily reach it. When an object is advancing towards you quickly, you will feel the object slamming towards your head, which will surprise you. p2p online movies: With the development of the Internet, P2P, as an emerging form of online movie playback, has become a favorite movie playback situation among netizens due to its advantages of fast speed, less buffering, and the more people there are, the less stuck it is. The movie playback format is also called online movies, which allows you to watch the movies you want to see in the ocean of the Internet without leaving home. Character movie; it has not yet been launched, but as it develops, it will soon enter our lives. In fact, character movies are movies shot from the first-person perspective. The games we play count.
