How to see the pictures stereoscopically

The pictures make use of the so-called parallel viewing method (also known as wall-eyed or wide-eyed viewing). Seeing them stereoscopically requires concentration and may take a while to master.

Adopt a comforatable viewing distance from the monitor so that your eyes are not straining in any way (in these pictures the stereoscopic effect is not dependent upon distance, since the two images are fixed in space and present the same information to the eyes regardless of the viewing distance).

Whilst focussing on the pictures, allow your eyes to relax so that you begin to see a double image of the picture (this simply means that your eyes are no longer converging on the picture, but are looking parallel to each other, as they do in the distant vision position).  In effect, you should see FOUR individual pictures - two generated by each eye.

You may try tilting your head slightly to one side when you relax your eyes.  The double images should be easier to see, slightly overlapping.

Concentrate on the picture on the RIGHT (this is the picture in which the stereoscopic effect will be seen).  Whilst your eyes are in the relaxed state you should become aware of an image very close to it (which is in fact the left-hand picture seen by the other eye).  By carefully adjusting the relaxed state of the eyes, you should attempt to merge the left picture with the right picture.  If you have your head slighly tilted, slowly return it to the upright position and attempt to merge the images.

Your focus should remain on the screen and the pictures should not appear blurred.  Your head MUST be level with the picture for the effect to work.

When the two pictures have become merged the brain will register the images as it would in reality, and the stereoscopic effect should pop into view.  Distance in the picture should become very apparent and a surprising amount of detail will be seen.
