Parallel viewing

From Photo-3d

Pairs of stereo images for parallel viewing have the left image placed on the left side, and the right image on the right. To view, “defocus” your eyes in a manner similar to day-dreaming. After a time you will begin to see “double” images. If you begin to concentrate on the images in the center of your view, you should be able to get them to merge into a single 3D image.
