Stereographs are devices capable of building a three-dimensional image out of two photographs that have about two and a half inches difference between them so that it could imitate the two eyes’ real field of view. Combining these images into a single one with the help of stereoscope, a person can experience the illusion of the image’s depth. Stereoscope uses the same principle as in human binocular vision. Our eyes are separated by about two inches, so we see everything from two different angles. When the brain combined those views in a single picture, we get the spatial depth and dimension. Stereographs were extremely popular between 1850 and 1930 all around the world. Millions of stereographs were made during that time. There was a broad range of themes: landscape, travel, historical moments, nature disasters, architecture and many others. Nowadays, simply launch this collection full screen and put your mobile device in Google Cardboard Viewer.
During the Civil War, photographers produced thousands of stereoviews. Stereographs were popular during American Civil War. A single glass plate negative capture both images using a Stereo camera. Prints from these negatives were intended to be looked at with a special viewer called a stereoscope, which created a three-dimensional ("3-D") image. This collection includes glass stereograph negatives, as well as stereograph card prints.
