Answer:
To capture and reproduce the image of movement, various devices are built based on the phenomenon of retinal persistence (fraction of a second in which the image remains in the retina), discovered by the English Peter Mark Roger in 1826. The photography, developed simultaneously by Louis- Jacques Daguerre and Joseph Nicéphore Niepce, and the motion capture and analysis research represent a decisive advance toward the cinematographer.
But specifically speaking of the technique that allows the capture of the image with a movie camera, that is, photography for cinema, all of it is aimed at obtaining an accurate image, consistent with the proposal of the film and as objective as possible within this proposal. . To do so, you need to know a little of traditional, static photography, because in it are all the bases for film photography. Strictly speaking, they are exactly the same photography, but cinema photography encompasses a kinetic dimension, that is, it includes movement.
But the main difference between them is that the camera has a lens system to let in light and print an internal film; and the projector is equipped with a lens system and an internal lamp whose function is to promote light output from its interior. On the way, the light passes through a transparency (the slide film) and the lens forms the image of the frame out of the device, thus making the reverse path of the camera.
The best support for recording this image is photographic, where there is precisely an image formed on a transparent base, allowing its projection for both copy and enlarged display of the original image.
