What inspired the Lumiere brothers in France to invent the film machine?

Lumiere brothers summed up their predecessors' experience and invented the world's first relatively perfect, flexible and portable portable "mobile movie machine" in 1894. This is a machine that can take pictures, show and develop. The film machine consists of a black box with a traction mechanism for intermittent motion of 35 mm film and a shutter rotation mechanism.

It is equipped with a camera lens to take pictures at the frequency of 12 frames per second. When the picture is still, the shutter opens and the film is exposed. When the shutter is closed, the film moves forward to get a negative.

Then take off the lens, put the negative film on the machine, paste another unexposed film, run it under the illumination of light source, and get the positive film after exposure. The film machine is also equipped with a projection lens. After loading the film, put the machine under the light bulb, and the light beam passes through the film and lens, and the camera becomes a projector.

Born in a photographer's family, and having a strong interest and rich experience in photography technology, French Millul brothers, inspired by sewing machines, referred to Edison's method of conveying film by using film perforation, and studied the shortcomings of predecessors in the research and development of projectors, and invented the world-famous "mobile film machine".

On February 28th, 1895 1895, Lumiere held a screening in the "Big Cafe" in Kaputin Street, showing the earliest movie clips in the world, such as Train Entering the Station, Factory Gate and Baby Lunch.

Although these clips have no substantive content, no theme, no story, no performance and no editing, they are just fixed-seat, single-shot video records of real scenes, but they brought great joy to the audience at that time, which made people feel very shocked, curious and even scared.
