2.5.10 Ambrotype and Carte de Visite Comparison
The latter image, a portrait of an American soldier (1861-1865), provides a good example of an ambrotype. Devised from the Greek word meaning "imperishable," the ambrotype was similar to the daguerrotype but lacked a highly reflective surface and was less expensive to make.
Both processes served their individual purposes. Ambrotypes provided a cheaper alternative to the daguerrotype, while still maintaining much of the ornateness (usually surrounded by ornate frames), and carte de visites provided for small images that could be used for social situations.
