Historical Stereographs

Drop in

A stereoscope is a device for viewing a stereoscopic pair of separate images, depicting left-eye and right-eye views of the same scene, as a single three-dimensional image.

A typical stereoscope provides each eye with a lens that makes the image seen through it appear larger and more distant and usually also shifts its apparent horizontal position, so that for a person with normal binocular depth perception the edges of the two images seemingly fuse into one “stereo window”. In current practice, the images are prepared so that the scene appears to be beyond this virtual window, through which objects are Old Zeiss pocket stereoscope with original test image sometimes allowed to protrude, but this was not always the custom. A divider or other view-limiting feature is usually provided to prevent each eye from being distracted by also seeing the image intended for the other eye.

NYPL Labs is proud to bring you the Stereogranimator, a tool for transforming historical stereographs from The New York Public Library and other participating organizations into shareable 3D web formats. This site is all about participation, fun, and experimentation.

Come and see our selection of historical stereographs, using a Victorian style stereoscope, an early 60’s classic or NYPL Labs Stereogranimator, a tool for transforming historical stereographs from into shareable 3D web formats.
