Stereographs create the illusion of three-dimensional depth from images on a two-dimensional plane. Human vision uses several cues to determine relative depths in a perceived scene. Between the 1840s, when stereographs were first made, and the 1930s, when they were supplanted by movies and other media, millions of stereographs were produced. Stereographs came in a variety of formats that reflected the era and region in which they were produced. At first stereotypes were produced as daguerrotypes and ambrotypes, but stereographs became much more common once they began to be printed on card stock. Initially photographers created stereographs by taking one photograph, then slightly shifting the camera to a new position. Cameras with multiple lenses were eventually used, although some photographers employed a rig with two cameras. there were hundreds and maybe thousands of stereographic pictures taken of Minnehaha Creek and falls over the years. Here, in no particular are a few of my favorites.
