The History of Photography
Photography was derived from the Greek terms "photo" (light) and "graphien" (to draw). The first photo ever taken was by Joseph Niepce (right) in 1827, but it required 8 hours of light exposure and disappeared soon after appearing. In 1829, Louis Daguerre (left), a professional scene painter for the opera who had an interest in this new concept, formed a partnership with Niepce and together they worked to create an improved version of Joseph's work. In 1833, Niepce passed away, but Daguerre kept on researching and by 1839, he had created the first practical process of photography.

In 1841, William Henry Fox Talbot (left) invented the Calotype process, which is the first negative-positive process enabling the first multiple copies to be made.
In 1871, Richard Leach Maddox (right) patented the gelatin dry plate process - this meant you wouldn't have to develop negatives immediately. |
