Top of Sharington's Tower, Lacock Abbey, Taken from the Roof above the South Gallery, October 14, 1840 , Photogenic drawing from paper negative, Image: 5 13/16 × 7 1/16 in. (14.7 × 17.9 cm), irregularly trimmed, Photographs, William Henry Fox Talbot (British, Dorset 1800–1877 Lacock), Talbot's earliest camera images required exposures of an hour or more, but on September 23, 1840, he made a startling discovery that dramatically increased the medium's potential. He found that an exposure of mere seconds, leaving no visible trace on the chemically treated paper, nonetheless left a latent image that would appear when immersed in a solution of gallic acid
