2)  Albumen print is the earliest form of photographic paper in the 1830's. The main ingredient of the albumen process begins with fresh eggs. Then a contamination from blood yolk or the stringy tissues known as chalazae was carefully avoided. An appropriate amount of chloride usually 1 1/4 was added. The albumen was beaten to a froth. This mixture was allowed to stand until it had settled back to a liquid state, then was filtered through muslin. If a fermentation step was employed then the chlorides were added after the beating; settling and fermentation were completed.

Nicéphore Niépce

I find this photo that Nicéphore Niépce took is very interesting. The way how the shadows comes in and the outline of the buildings. Nicéphore Niépce is a french inventor who was born on March 7, 1765. He's most noted for producing the world's first known photograph in 1825; Niépce also invented the Pyréolophore. He later died in July 5, 1833.
