1 Photography? What is it?

Ultimately, my hope is to amaze myself. The anticipation of discovering new possibilities becomes my greatest joy. ~Jerry Uelsmann

3 Photography At it’s core…it is a technical process Photo + graphy
photo = light graphy = draw/write The first man to use the word photography was Sir John Hershcel in 1839

4 Photography is basically
Photography is an art & science that combines sciences such as physics, chemistry, and optics with creative skills. Photography combines physical and technical skills. We do this, either on paper with chemicals, or on a computer screen with pixels.

5 It is many things Photography is vision Photography captures moments
A mode of expression styles art documentary commercial

6 A Brief History In 1727, Johann Schulze – A German physicist, found that certain silver salts changed color when they were exposed to light.

7 Joseph Niepce In 1862, Frenchman Joseph Niepce, was the first to successfully create a permanent photograph using a camera obscura to capture images made of varnish on metal plates.

9 Daguerrotype Louis Daguerre invented the “daguerreotype” in These were a positive black and white image on a mirror-polished, silver-plated copper sheet. It instantly grew in popularity & within a year of its invention, it was used all over the world. Although a breakthrough, its popularity faded when people realized that the copper sheets could not be used to make additional prints. Each print was a one-of-a-kind original.

11 Wet Plate Collodion This is a photographic process developed by Frederick Scott Archer in the 1850’s. This process is different from Dagguerotypes because instead of metal plates, light-sensitive materials are placed on glass. Glass is coated with a mixture of chemical such as bromide, iodide, and chloride which is dissolved in collodion (guncotton dissolved in ether and alcohol).

12 The solution is applied to glass and turns to a type of gel
The solution is applied to glass and turns to a type of gel. While the solution is still wet it is placed in the camera then exposed to light in order to capture the image. While it dries it is no longer light sensitive and the image becomes permanent. Exposure time took 30 minutes.

13 Tintype Similar to the wet plate process
Rather than glass, iron is used which is more stable Light sensitive material is coated on iron Surface is already dry so photographers didn’t have to wait. This process was used at fairs & carnivals

14 Dry Plate Glass plate is coated with a gelation emulsion made of silver bromide The plate could then be stored until ready to be used and after exposure it could be taken to a darkroom for developing. Dr. Richard L. Maddox developed this in 1871 and by 1879 it got so popular that the first dry plate factory was produced.

15 History Meanwhile, in 1834, William Henry Fox Talbot, used soaked sheets of paper in silver chloride instead of metal plates, and put them inside the camera obscura to make paper negatives. By 1839, he was contact printing his negatives to other sensitive sheets to create positive prints. This is the basis for photographic processes that followed.

17 History continued In 1888, George Eastman (an American), created the first point-and-shoot camera, called the Kodak. A year later, he introduced a version of the Kodak that was preloaded with enough film to make 100 exposures. Photography was now accesible to both amateurs and professionals. Prior to this he also patented a dry plate camera & opened a dry plate factory
