The carte de visite (abbreviated CdV or CDV, and also spelled carte-de-visite or erroneously referred to as carte de ville) was a type of small photograph which was patented in Paris, France by photographer André Adolphe Eugène Disdéri in 1854, although first used by Louis Dodero.
Each photograph was the size of a visiting card, and such photograph cards were traded among friends and visitors. Albums for the collection and display of cards became a common fixture in Victorian parlors. The immense popularity of these card photographs led to the publication and collection of photographs of prominent persons.

The carte de visite was quickly replaced by the larger cabinet card. In the early 1860s, both types of photographs were essentially the same in process and design. Both were most often albumen prints, the primary difference being the cabinet card was larger and usually included extensive logos and information on the reverse side of the card to advertise the photographer’s services. However, later into its popularity, other types of papers began to replace the albumen process. Despite the similarity, the cabinet card format was initially used for landscape views before it was adopted for portraiture.
The cabinet card was a style of photograph which was widely used for photographic portraiture after 1870. It consisted of a thin photograph mounted on a card typically measuring 108 by 165 mm (41⁄4 by 6 1⁄2 inches).
