The first permanent photograph (later accidentally destroyed) was an image produced in 1826 by the French inventor Joseph Nicéphore Niépce. His photographs were produced on a polished pewter plate covered with a petroleum derivative called bitumen of Judea, which he then dissolved in white petroleum. Bitumen hardens with exposure to light. The unhardened material may then be washed away and the metal plate polished, rendering a positive image with light regions of hardened bitumen and dark regions of bare pewter. Niépce then began experimenting with silver compounds based on a Johann Heinrich Schultz discovery in 1727 that silver nitrate (AgNO3) darkens when exposed to light. [via Wikipedia]
