In 1864 as the war raged on and funding became thinner the Congress passed an act that also taxed photographs, ambrotypes, and daguerreotypes.

A daguerreotype has no negative so if you find a daguerreotype you know you have a one-of-a-kind image.

They look like a mirror and the images jump out at you, appearing very 3 dimensional.

By 1854 Ambrotypes had entered the photography scene and were widely used.

The ambrotype was a glass negative backed with black material, which enabled it to appear as a positive image.
