Calotype Photography
Description
Calotype, also called Talbotype, is an early photographic technique invented by William Henry Fox Talbot of Great Britain in the 1830s. In this technique, a sheet of paper coated with silver chloride was exposed to light in a camera obscura; those areas hit by light became dark in tone, yielding a negative image. The developed image on the paper was fixed with sodium hyposulfite. The “negative,” as Henry Talbot called it, could yield any number of positive images by simple contact printing upon another piece of sensitized paper.

Information
What is it: Calotype is an early photogenic process invented in 1841 by William Henry Fox Talbot, using paper coated with silver iodine.
When was it created: Calotype photography was invented in 1841.
What does it do: In this technique, a sheet of paper coated with silver chloride was exposed to light in a camera obscura; those areas hit by light became dark in tone, yielding a negative image.
How has it helped us today: It has helped us today because if Henry Talbot would have never invented this we would have never come to know how to make pictures. The "SELFIE" wouldn't exist!
Interesting Facts: The Calotype process produced a translucent original negative image from which multiple positives could be made by simple contact printing.
