The history of photography began in remote antiquity with the discovery of two critical principles: camera obscura image projection and the observation that some substances are visibly altered by exposure to light. There are no artifacts or descriptions that indicate any attempt to capture images with light sensitive materials prior to the 18th century. Around Johann Heinrich Schulze captured cut-out letters on a bottle of a light-sensitive slurry, but he apparently never thought of making the results durable. Around Thomas Wedgwood made the first reliably documented, although unsuccessful attempt at capturing camera images in permanent form. His experiments did produce detailed photograms , but Wedgwood and his associate Humphry Davy found no way to fix these images.

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.
