Stereoscopic photography recreates the illusion of depth by utilizing the binocularity of human vision. Because our two eyes are set apart, each eye sees the world from a slightly different angle. Our brains combine these two different eye-images into one, a phenomenon that enables us to "see," ever so slightly, around the sides of objects, providing spatial depth and dimension. Stereoscopic views, or stereographs, consist of two nearly twin photographs -- one for the left eye, one for the right. Viewing the side-by-side images though a special lens arrangement called a stereoscope helps our brains combine the two flat images and "see" the illusion of objects in spatial depth.

Op de website stereo.nypl.org vind je een enorme collectie stereografische afbeeldingen, geanimeerde gifs en anaglyfen. Het verschil tussen de klassieke stereografie en anaglyfen zit hem in het feit dat stereografie gebruikmaakt van twee foto’s die samen één foto met diepte vormen.
