1. History of Photography From pin holes to pixels

2. The Camera Obscura The camera obscura, literally "dark room” was used as an aid to drawing.

3. Camera Obscura Smaller table top camera obscuras were developed with lenses to help focus.

5. Joseph Nicephore Niepce Niepce produced the first photograph in June of 1827. He used chemicals on a metal plate placed inside of a camera obscura. Niepce produced the first photograph in June of 1827. He used chemicals on a metal plate placed inside of a camera obscura.

6. The first photograph

7. First Photograph The original window was covered up by remodeling, the view is reconstructed by computer 3D modeling.

8. First Method Exposure of the first photo took 8 hours. Niepce called his process “Heliographs” Niepce coated pewter plates with a tar like varnish made from Bitumen of Judea powder and oil.

9. Recreation of Niepce’s process The Powder is mixed with oil and spread on a metal plate. The plate is heat dried.

10. After exposure to light the parts of the coating hardens and sticks to the plate.

11. Louis-Jacques-Mande Daguerre Daguerre a well known stage designer painted huge realistic scenes he displayed in his Diorama, some 72 feet by 46 feet. Here is his 1824 oil painting “Ruin of Holyrood Chapel” considered his best work.

12. Niepce - Daguerre Partnership Daguerre contacted Niepce. After some meetings the men entered a 10 year partnership on December 14, 1829. Niepce sent Daguerre detailed information on all his work in heliography.

13. The Daguerreotype After years of experiments Daguerre discovered heated mercury vapor brought out the image from silver plates treated with iodine.

14. Daguerre’s process took 15 to 30 minutes of exposure in direct sun light and the level of detail was stunning. January 7, 1839 the daguerreotype was introduced to the Academy of Sciences, France.

15. Daguerre sold cameras and licenses to use the process. Photography spread quickly and improvements were made on the process.

16. Daguerreotypes Fredrick Douglas and Edgar Allen Poe

17. Fox Talbot Inventor of the negative positive process in 1840. Talbot’s Calotype used treated paper in a camera obscura. The image was invisible until developed and then a positive print made.

18. Not as sharp as a Daguerreotype the Calotype took three minutes or less exposure time and could make copies from the negative. Above photos by Scottish photographers Hill and Adamson

19. Wet Glass Plates Scott Archer, a sculptor whose interest in photography lead him to invent the wet - collodion process published in 1851. Archer did not apply for a patent. Archer made the process available to anyone. Scott Archer, a sculptor whose interest in photography lead him to invent the wet - collodion process published in 1851.

20. Wet glass photography became the dominate method of photography for the next 30 years. The daguerreotype faded in popularity. Photo of Lincoln by Alexander Gardner, Nov. 8, 1863

21. Matthew Brady In 1840 Matthew Brady, 17 years old at the time, took classes on the daguerreotype process. In 1844 he opened a photography studio in New York.

22. Portraits by Brady Brady set up a branch gallery in Washington DC and photographed presidents and members of congress. By 1853 Brady was using the wet plate process for all his photography.

23. Civil War Brady determined to document the Civil war left his portrait business and set out for the battlefield. The Wagon photo lab and Ulysses S. Grant, 1864

24. Eadweard Muybridge Horse in motion 1878

25. George Eastman 1880 introduced his “Dry-Plate” Process Set out to make the camera as convenient as the pencil. 1885 invented flexible roll film 1880 introduced his “Dry-Plate” Process Set out to make the camera as convenient as the pencil. 1885 invented flexible roll film

26. Eastman coined the slogan, 'you press the button, we do the rest,' when he introduced the Kodak camera in 1888.

29. Lewis Hine Used Photography to raise awareness of social issue and prompt change. Documented child labor 1908

30. Dorothea Lange Photojournalist Documented the great depression, Migrant Mother, 1936

31. Ansel Adams Developed the zone system for full tonal range Helped establish Kings Canyon national park.

35. Photojournalism With easy to use cameras, roll film, and camera flash the numbers of photographers and publications dedicated to photography grew.

36. Digital Photography The first digital cameras for the consumer-level market. The Apple QuickTake 100 camera, 1994. 640 x 480 pixel CCD Produced eight images stored in internal memory. It also had a built-in flash. The first digital cameras for the consumer-level market. The Apple QuickTake 100 camera, 1994. 640 x 480 pixel CCD Produced eight images stored in internal memory.
