Daguerroetypes, Albumen Prints, Stereographs, Carte de Visite, Mathew Brady and Alexander Gardner



1. What is a daguerreotype? What did the surface of a daguerreotype resemble? When were they prominent? What photographic process did the daguerreotype replace?
 A daguerreotype is a direct-positive process that creates a detailed image on a sheet of copper plated with a thin coat of silver without the use of a negative. The surface of a daguerreotype resembled a mirror, and at the peak of its popularity in 1850, the daguerreotype replaced Heliography.

2. What is an "albumen" print? What was the main "ingredient" of the albumen process? When did the albumen process die out?

The albumen print was divided silver and gold image dispersed in a mold of egg white. It died out sometime towards the 1920's.

3. What is a "stereograph"? When were they popular?
 Two almost identical photographs were placed on cardboard side by side and viewed with a stereoscope. When viewed this way, the photograph appeared three-dimensional, and were popular because of this.
