A History of Light and Lighting |
 | | Daguerre, working, with J. Nicephore Niepce, developed the daguerreotype, a photograph formed on a copper plate coated with silver and treated with iodine vapor. |
| | In 1826, Joseph Nicephore Niepce, a French lithographer used a small camera obscura to capture an eight hour exposure on a sensitized sheet of pewter. |
| | Although the results would have been quite crude, Niepce had brought together the concept of the camera obscura with the ability to form an image through a chemical reaction triggered by light. |
