The history of photography began officially in the year 1839, with the worldwide dissemination of the first photographic procedure: the daguerreotype. As background of the photograph, are the dark chamber and the investigations on photosensitive substances, especially the blackening of the silver salts. Ibn al-Haytham 965 to 1040, carried several experiments on the dark chamber and the pinhole camera.
At the beginning of the 19th century, in 1824, the French scientist Nicéphore Niepce obtained some first photographic images, unpublished. The oldest photograph preserved is a reproduction of the image known as View from the window in Le Gras, obtained in 1826 with the use of a dark chamber and a plate of pewter coated in bitumen.
