Stereoscopic photographs can provide the strong impression that you are physically occupying the landscape rendered.
By relaxing the eyes, almost allowing them to "cross", many people can see a third, three-dimensional image, appear between these two pictures. The original pictures were taken in a stereoscopic camera, onto large format glass plates, to be viewed in a stereoscopic viewer. One image was taken for each eye to view independently. When viewed simultaneously and fused in the brain, a three dimensional image appears.
Your contribution is welcome.
