Ambrotype: A Negative Positive (see our slideshow for the collection)
By the summer of 1855 the ambrotype was fast becoming the most popular form of photography among Americans, preferred even over the daguerreotype. The popularity of the medium was owed to the absence of the highly reflective surface that characterized the daguerreotype, which many persons found troublesome. An ambrotype is most simply described as a collodion glass-plate negative that appears to be a positive when viewed against a dark surface. This transformation is caused, with reflected ambient light, by the clear areas of the negative appearing dark, and the opaque silver areas bright.
