3. Photography Photography: Originally coined by Sir John Herschel in 1839 – Derived from the Greek words for “light” and “writing” The invention of photography owes its origins to two processes – Camera Obscura – CHEMISTRY!!

4. Camera Obscura Means “Dark Box” Dates back to 9 th century- Alhazen During the Renaissance, Leonardo da Vinci used this process to draw

5. How does it work? – Light from outside passes through the hole and strikes a surface inside, where it is reproduced, rotated 180 degrees (thus upside-down), but with color and perspective preserved.

6. Abe Morrell: a new photographer using old methods Contemporary photographer Born in 1948 From Havana, Cuba Received a Master’s of Fine Arts (MFA) from Yale University School of Art Shown work in galleries and museums around the US including: Museum of Modern Art, The Metropolitan Art Museum, and The Chicago Art Institute

9. The Chemistry of Photography In 1727, John Heinrich Schulze discovered that certain liquids change color when exposed to light At the beginning of the 19 th century, people could capture an image, but they eventually faded away In 1827, the first permanent picture was made by Niepce Louis Daguerre partnered with Niepce to eventually invent the Daguerrotype

10. Daguerrotype Invented by Louis Daguerre in 1839 through experimentation with light sensitive plates and salt Expensive and could not be replicated Daguerreotype Process – formed on a highly polished silver surface like copper or metal – Several minuets to take 1 image – Dipped in a salt solution – Requires lots of polishing

12. William Henry Fox Talbot Wanted to rival the Dagerrotype Invented the Calotype around 1839 – He experimented with botanical images “ ‘how charming it would be if it were possible to cause these natural images to imprint themselves durably, and remain fixed upon the paper.’" – He would place botanical specimens on light sensitive material, expose it to light, then wash off the unexposed material leaving behind an imprint

14. Important Dates and Inventions 1835: 1 st paper negative produced by Henry Talbot 1848: perfection of the Albumen process – Used glass plate that was coated with egg white treated with potassium iodide, processed with silver nitrate 1851: Collodion process by Frederick Scott Archer – Wet Plate: coating, exposure, and development could be done while plate was still wet

15. Collodion process

16. Dates and Inventions Continued 1871: Dry Plate Process – Dr. Richard Maddox discovered was of using Gelatin instead of glass or metal for the basis of a plate – Quick to develop and process 1884: Invention of flexible film by George Eastman 1888: Founding of Kodak by George Eastman
