How was the film invented?

The birth of film is closely related to the development of photography technology. As we all know, the original film is composed of photos, and the photos are constantly switched at a certain speed to give people a visual feeling, and the characters are moving, showing the feeling of video.

As early as 1823, silver plate photography was born, but the photography technology was extremely immature at that time. At that time, it took 14 hours for a photo to be exposed. As you can imagine, a two-second video needs a lot of photos, which is a big project, not to mention a movie with dozens of minutes. Until 185 1, the exposure time of photos was greatly shortened, and the final exposure time was reduced to a few seconds, thus the concept of dynamic photos was born. 1878, Edward Mucci found out? Visual retention? The principle can connect 24 photos into an activity. Through this discovery, he also applied for a patent activity for the method and device of shooting animals.

Later, with the improvement of different people and the joint efforts of many people, the technology of photography gradually matured. With the material, the gameplay is produced, and that is projection. 1888, the French invented the optical film machine. 1894, American Edison invented the thin-film mirror. But it wasn't really the beginning until the Lumiere brothers in France invented it? Mobile movie machine? This marks the birth of real film projection, and only such a machine can have the functions of shooting and projection at the same time.

1895, 1895, used by two brothers in Paris? Mobile movie machine? Ticket sales for the first time, showing 12 movies, one minute each. This is the birth of a real movie. After people successfully mastered the way of shooting and showing movies, it made the film industry flourish, from the initial film to the current digital film, from the previous specification of 24 photos per minute to the current 64 photos, and then to the current Blu-ray and HD.
