This collection contains nearly 65 portraits in early photographic processes ranging from daguerreotypes, ambrotypes, to tintypes. These early photographic processes were commonly used starting in the 1840s through the 1870s. Due to rapid innovation during the infancy of photography, their use superseded each other. Daguerreotypes, images on silver-coated copper plates, were replaced by ambryotpes, images on transparent glass plates, which were then superseded by tintypes, images on thin iron plates. Unfortunately many of the subjects in these portraits are unknown as the photographs were acquired from third-parties.
