Making two-dimensional photographs come to life is magic. The stereoscopic images that are displayed here give the viewer a window into another world. A living, breathing, moving world. These illusions are created with digital cameras and open source software; some of the most up to date and futuristic technology, however, this process mimics what has been a part of the world for thousands of years. Humans have evolved to understand visual depth as our eyes are placed frontally, and we are able to use information derived from the different projection of objects onto each retina to judge depth. By using two images of the same scene obtained from slightly different angles, it is possible to judge the distance of an object. This is why our two eyes are where they are on our face.
Photographs capturing this perspective are two, flat, still images that illustrate the illusion of depth by jumping back and forth between the two images. Stereoscopes, Viewmasters, and 3D films, employ binocular vision by forcing the viewer to see two images created from slightly different positions. Take a look at a few test examples from some of my Middle School students.
