Here are 3 hyperstereo views of Seattle, taken from the observation deck of Smith Tower. These stereo pairs are set up for cross-eyed viewing.
Hyperstereograms are image pairs that are made using a larger than human interocular spacing. Huh? You know, the cameras are further apart than your eyes. The effect on a landscape is one of you being a giant.
Cross-Eyed Viewing Method
Some people can’t seem to do it, but practice a bit before you give up. Once you figure it out, the view is pretty stunning. To view the 3D image, cross you eyes until the 2 images converge into a “third” image which will appear in the center. Try to ignore the images in the periphery and concentrate on the center image. Relax your eyes and bring the middle (3D) image into focus. Practice on the small ones before trying the large versions. Keep your head level. If you still have trouble, try moving further away from the monitor.
