Who invented the moving negative continuous camera?

Muybridge's experiment built a bridge between still photography and dynamic film, which laid the foundation for the birth of film. But the photos he took were not really active movies. Because he didn't use a camera, but 10, 20 or even 40. The real active movie should actually start with Marley's invention of the "continuous camera for active movies".

E Marie (1830 ~ 1904) is a French physiologist. 1882, after hearing muybridge's dynamic photography, he began to explore. Different from muybridge, he did not use a row of cameras to shoot, but used a "fixed negative continuous camera" called a "photographic gun" to record a whole set of actions on the same master. This camera uses a special shutter to control exposure and can shoot 1 2 continuous moving pictures in1second. These continuous images of different stages of movement show continuous movements. The appearance of "photographic gun" created a precedent for continuous photography.

Later, Marley also invented the "moving negative continuous camera" by using Kodak film that just came out. This kind of camera is actually the prototype of modern film camera. 1888, 10 month, he dedicated his first photo taken with this camera to the French Academy of Sciences.
