Niepce takes the first photograph after searching for years for an image fixative
Photography, one of the great inventions of the early nineteenth century, was created by a Frenchman, sixty-two-years old Joseph Nicephore Niepce. He his brother were inventors, developing a boat driving by an internal-combustion engine, The pyrelophone, in 1798. From 1816, Niepce tried to ''fix'' an image produce by a camera obscura, which projects a scene onto a surface using the principle of a pinhole camera, sometimes with mirrors and lenses. He experimented with silver halide-coated paper and produced an image of window view, but the negative image venished when exposed in daylight.
He sought a way of producing a positive image, and in 1822 succeeded in making a contact print of an engraving onto a sheet of paper through the action of light on a glass plat coated with Judia bitumen. Two years later he made the first permanent images from the camera obscura, although these required an exposure time of many hours. He experimented with the material of photographic plate and in 1827 visited England to demonstrate his pewter technique to the Royal Society at kew. He did not win a prize because he would not reveal the chemicals used in this process. Around the same time, he produced a successful image-- a view from his window exposed over eight hours -- etched onto a tin plate, now regarded as the world's first true photograph. From 1829, he worked with Louis Daguerre; Niepce died in july 1833, leaving Daguerre to create the daguerreotype in 1839.
