Daguerreotype

A daguerreotype is the first successful photographic technique. The photo is made in the camera on a silver covered copper metal. The surface of the daguerreotype resembled a mirror. This was prominent from 1840 to 1841. The daguerreotype replaced the imaging system that was made by Nicéphore Niépce.

An albumen is the first method of producing a photograph on a paper base from a negative. The main ingredient for the albumen was egg whites that binder the photographic chemical to the paper. The albumen process died out in the end of the 19th century.

A stereograph is the mapping that projects a sphere onto a plane. This was popular in the 17th and 18th century.

A carte de viste was a type of small photography and was usually made with an albumen print. These were used at visiting cards, or postcards that were traded among friends.

Matthew Brady was known for photographing the civil war and introduced the daguerreotype. 

Alexander Gardner worked for Matthew Brady and introduced the woodward solar system, and photographed President Lincoln and his secretaries. They were both active during the civil war.
