What do you do with an incorrect photograph? I found one linked to an ancestor that died abt. 1870 .
Daguerrotypes (1839–1860): Daguerrotypes are made of silver-plated copper with a polished surface. Because they’re fragile, they’re usually covered with glass and can be found in small cases padded with satin or velvet.
Tintypes or Ferrotypes (1856–early 1900s) Tintypes were popular during the U.S. Civil War. They're made of a thin sheet of iron coated with black varnish; they're durable, so that soldiers could carry them and mail them home.
Cabinet Cards (1866–1920s): Most photos taken in the late 1800s are cabinet cards. These photos were printed on thin paper and mounted on a thick card. The front of a cabinet card usually contains the name of the photographer or studio.
Portrait Postcards (1900–1920s): Portraits printed with postcard backs became popular at the turn of the century. Pre-1907, postcard styles changed frequently, but most postcards printed after 1907 are similar to modern-day postcard layouts.
The Black and White Snapshot (1900–1960s): In 1900, Kodak launched the Brownie camera, thus making cameras affordable and easy to use. Many people purchased the Brownie camera during this period.
Color Transparencies or Slides (1940s–1970s): Color film became widely available in the 1940s and 1950s.
