Scenic photos from that period are mostly found as Stereo Cards, though there are many in the large sized card mounted formats as well.

AMBROTYPE The Ambrotype is essentially a glass negative with a black background that makes the image appear positive. Invented about 1854, the form lost popularity in the early 1860's when tintypes and CDV's replaced them. There are some wonderful ambrotype portraits still in existence, yet the process is much neglected by authors.

The CDV is easily distinguished from other card mounted photos by its size, typically 2.5 x 4 inches (63 x 100 mm) or slightly less.

None of these other sizes are as common as the CDV, Cabinet Card and Stereotype.

SAMPLE CARTE-De-VISITE Carte-de-Visite's, or CDV's, are a type of card mounted photograph introduced in the mid 1850's and tremendously popular especially in America and Europe from 1860 until almost the turn of the century.


Listed here are the main types of historic photographs one is likely to encounter.

Probably 80% of the 19th century portrait photos the genealogist or local historian finds will be card mounted, particularly CDV's and Cabinet Cards; and another 10 to 15% will be tintypes.
