Stereo (3-D) Views

Destruction Caused by the Flood

Page 2 of 4

Many photographers took special "stereo views" that made their photos look three-dimensional. First they took the pictures with a camera that had two lenses (like binoculars). The pictures were printed side-by-side. People used a viewer called a "stereopticon" to blend the two pictures into one three-dimensional image. The "Viewmaster" and 3-D books and movies of today work in a similar way. See a stereo card and stereopticon on this page.

To help you see as much as possible from these photographs, use the tool "Reading a Photograph." If you have 3-D glasses (with one red lens and one blue lens), you can view the same photographs here in 3-D .
