The First Known Photo
This first image, in 1826, which Nicephore Niépce called "point de vue", point of view, is a direct impression of reality, different from plants, images on paper using the camera obscura.
The image was taken on a tin plate - a film, lead and tin alloy, after an eight-hour exposure. He did it after working with five walnut chambers, the diaphragm went from cardboard to iris discs, used scales and bellows devices, using continuous paper, the precursor of the coil, in one of the chambers. It was taken by the father of the photograph of the window of his house in the commune of the department of Doubs, in the French Burgundy.
