First Photograph Ever Taken
Long before the first public announcements of photographic processes in 1839, Joseph Nicéphore Niépce, a scientifically-minded gentleman living on his country estate near Chalon-sur-Saône, France, began experimenting with photography.
Fascinated with the craze for the newly-invented art of lithography which swept over France in 1813, he began his initial experiments by 1816. Unable to draw well, Niépce first placed engravings, made transparent, onto stones coated with light-sensitive varnish of his own composition. These experiments, together with his application of the then-popular optical instrument, the camera obscura, would eventually lead him to the invention of the new medium.
In 1824 Niépce met with some degree of success in copying engravings, but it would be two years later before he utilized pewter plates as the support medium for the process. By the summer of that year, 1826, Niépce was ready. In the window of his upper-story workroom at his country house, Le Gras, he set up a camera obscura, placed within it a polished pewter plate coated with bitumen of Judea (an asphalt derivative of petroleum), and uncapped the lens. After a day-long exposure of eight hours, the plate was removed and the latent image of the view from the window was rendered visible by washing it with a mixture of oil of lavender and white petroleum, which dissolved away the parts of the bitumen that had not been hardened by light. The result was the permanent direct positive picture you see here—a one-of-a-kind photograph on pewter. It renders a view of the outbuildings, trees and landscape as seen from that upstairs window.
The first permanent photograph (later accidentally destroyed) was an image produced in 1826 by the French inventor Joseph Nicéphore Niépce. His photographs were produced on a polished pewter plate covered with a petroleum derivative called bitumen of Judea. Bitumen hardens with exposure to light. The unhardened material may then be washed away and the metal plate polished, rendering a negative image which then may be coated with ink and impressed upon paper, producing a print. Niépce then began experimenting with silver compounds based on a Johann Heinrich Schultz discovery in 1724 that a silver and chalk mixture darkens when exposed to light.
