Author: Joseph Nicephore Niepce (1765-1833)
First successful photograph produced (an 8-hour exposure). [A type of asphalt (bitumen of Judea) was coated on metal plates. After exposure it was washed in solvents, the light areas were shown by the bitumen, dark areas by bare metal. Exposed to iodine, the plate darkened in the shadowed areas.]
