1907.6 1907, the photography pioneer Lumiere Brothers announced that they had invented a three-color photo production process. With this process, color photos became popular. The original technology was expensive and complicated. On June 1907, photography pioneers August and Louis Lumière said that they had developed a feasible method to make color photos. It uses three independent images of the shooting scene as the basis, and makes each of the three images into a negative with one of the basic colors of red, green and blue by using an appropriate color filter. Then, put the particle screen on the three-color negative. When the screen is placed on it and the light shines on them, a full-color image appears. Although color photos were made as early as 186 1, when james maxwell gave his first technical performance at the Royal Society of London, their application was still limited because the technology used to make full-color photos was expensive and complicated. The Lumiere brothers' technology can popularize color photography. French brothers Auguste Lumière and Louis Lumière invented movies and projectors. In addition to the process of making three-color photos, they are also inventors of movies and projectors. At that time, the advanced photography technology developed by Lumiere brothers was not taken seriously. As early as 1895, the Lumiere brothers started shooting with portable cameras. Compared with the model developed by Thomas Edison, this machine has obvious advantages. In the following five years, the Lumiere brothers made hundreds of films, most of which reproduced outdoor activities in people's daily lives. The two brothers not only transformed the "peep show" created by American inventor Edison, but also enlarged their moving images through projection so that more people could watch them at the same time. On Saturday, February 28th, 1895, 1895, an "active movie" was held in the basement of Cafe Capesin Road 14, Paris, France. The movies shown included the factory leaving work and the train entering the station. Although this film is not the first public screening in history, it is often regarded as the first screening in the world because it is closer to the later viewing form.
