Early fixed images

The first partially successful photograph of a camera image was made in approximately 1816 by Nicéphore Niépce using a very small camera of his own making and a piece of paper coated with silver chloride, which darkened where it was exposed to light. No means of removing the remaining unaffected silver chloride was known to Niépce, so the photograph was not permanent, eventually becoming entirely darkened by the overall exposure to light necessary for viewing it. Later, in 1826, he used a sliding wooden box camera made by Charles and Vincent Chevalier in Paris, France. He made his first permanent camera photograph in 1826 by coating a pewter plate with bitumen and exposing the plate in this camera. The bitumen hardened where light struck. The unhardened areas were then dissolved away. This photograph still survives.
