History of Photography | 4th Century

 

 

 

 

 

 

 

 

Daguerreoty was invented by Louis Daguerre in 1789.

Advantages: Reduced exposure time to half and hour and created a direct positive image.

Disadvantages: This process was very expensive and not available to everybody.

 

 

 

 

 

 

 

 

 

 

 

 

 

 

The Calotype process was invented by William Fox Talbot.

Disadvantages: The process was time consuming and required two steps.

 

 

 

 

 

 

 

Frederick Scott Archer was the inventor of the Wet Collodion Process also known as the Wet Plate Process.

Advantages: The process reduced exposure time to 2-3 seconds and was significantly cheaper than other processes at the time.

Disadvantages: This process was very troublesome.

 

 

 

 

The Dry Plate Process was invented by Richard Maddox.

Advantages: The dry plates were very convenient and had greater sensitivity.

Disadvantages: This process had excessive exposure times.

 

 

 

The first photograph of a human was taken by Louis Daguerre:

 

Photo emulsion is any medium that is sensitive to light that is used for preparing photographic film.

Eastman named his company Kodak simply because he liked the letter K and thought it was a strong letter. He also liked that Kodak is hard to misspell or mispronounce.

Polaroid Film: The process starts with a chain of chemical reactions where the colors from the dye are brought up from lower layers as well as the acid layers. Once the chemicals meet, they react to make the image turn clear. Then the image slowly appears until it is fully developed.
