Photography (1 janv. 1826 – 1 janv. 1827)

Description:

In the early 1820s, Nicéphore Niépce became interested in using a light-sensitive solution to make copies of lithographs onto glass, zinc, and finally a pewter plate. He then had the great idea to use his solution to make a copy of an image in a camera obscura (a room or box with a small hole in one end through which an image of the outside is projected). In 1826 or 1827, he made an eight-hour-long exposure of the courtyard of his house, the first known photograph.
