Untitledpresentation 1

  1. 1. YR 10 - Photography Foundation pt2
  2. 2. The quest to capture reality 1724 - johann Heinrich Schultz discovers that that certain silver salts, most notably silver chloride and silver nitrate, darken in the presence of light, and for using those effects to capture temporary photographic image directed onto silver compound it changes colour 1827 - The scientist Joseph Niepce was successful in fixing the first projected image of his view from the window in Le Gras, South France http://www.hrc.utexas. edu/exhibitions/permanent/firstphotograph/
  3. 3. Louis Jacques Daguerre Louis Daguerre worked with Niepce in his quest to fix the projected image. Daguerre was a painter of stage sets and illusionistic scenery for The Diorama, a popular visual entertainment in Paris.
  4. 4. Louis Jacquescques In January 1839,Daguerre officially announced the invention of the Dagerreotype, a type of photograph which laterally reversed and monochromatic printed onto a metal plate.
  5. 5. The competition Around the same time as the invention of the Daguerreotype, an English scientist called William Henry Fox Talbot developed another type of photograph called the Calotype. The Calotype had a distinct advantage over the Daguerrotype: It could be reproduced as a negative as opposed to being a single unduplicated image
  6. 6. A Question of Quality In terms of mass production, Talbots Calotype was far superior. However, it lacked the sharpness and overall quality of the Daguerreotype and this made it less popular in the early years. However, the Calotype was improved over time and advances in paper technology led to better processing. Thus the calotype soon became the most popular type of photography that is still used today.
  7. 7. The first Calotype - Negative / Positive
  8. 8. Talbots Photogenic drawings Talbots initial photographic experiments involved producing photogram’s or what he refered to as “Photogenic Drawings”.
