  A History of Photography, by Robert Leggat: STEREOSCOPIC photography
Stereoscopic, or 3D photography, works because it is able to recreate the illusion of depth.
The stereoscope took off in a big way when Queen Victoria and Prince Albert observed one at the exhibition at the Crystal Palace, and Brewster presented her with a stereoscope made by Duboscq.

  Stereoscopic Vision
Stereoscopic vision is essential for predator animals who catch other animals (owls for example), but has secondary importance for animals who are chased (such as rabbits or deer).
Useful stereoscopic vision while we are moving about fades out about 200 meters away, (1 arc minute) (In the laboratory, stereo vision can be measured at best down to 5 arc seconds: meaning stereo vision theoretically extends to 2.7Km).
One of the deficiencies of stereoscopic photography is the inability to use head movements to resolve problems of 3D perception.

 REPRESENTATION OF STEREOSCOPIC DEPTH INFORMATION IN MEMORY
Stereoscopic depth cues are formed by disparities in the locations of objects in the images formed on the two eyes, and are naturally used by most observers to recover the distances to objects in the world.
Grimson argues that use of stereoscopic disparities to recover accurate depth requires precise calibration of the viewing apparatus and such precision may be beyond the capacities of the human visual system.
While the use of stereoscopic depth cues for perceiving objects has been widely studied, the representation of these depth cues in memory has received little attention, and the question of whether stereoptic depth cues are preserved in memory is still unclear.

 History of Photography in Brighton
To describe this viewing instrument, Wheatstone coined the term "Stereoscope" (from the Greek words 'stereos' meaning "solid" and 'skopein' meaning "to look at") With the advent of photography, Wheatstone's reflecting stereoscope, which utilised mirrors, could be used to view a pair of almost identical photographs and give the illusion of depth.
The reflective surface of a silvered copper plate was not ideal for stereoscopic effects and the process did not lend itself to the manufacture of large quantities of stereo pictures.

 Creating stereoscopic images with POVRay
The figure on the left shows how the stereoscopic camera pairs are normally set up [1]: The left and right camera have a distance of e, called the stereo base which corresponds to the eye distance and is often set to 65mm (being the average human eye distance).
When you look at a stereoscopic image, objects on the stereoscopic window appear to be painted on the image projection screen, objects with greater depth look like being behind the screen while those between the stereoscopic window and the camera location seem to be in front of the projection plane.
StereoPOV has some hints on how one should set up the scene and the camera for a nice stereoscopic scene: You should place the foreground objects about at the depth of the stereo window and always keep in mind which projection device you will be using in the end.

 Dr. Dobb's | Stereoscopic Imaging | July 22, 2001
Stereoscopic imaging gives you the ability to deliver a user interface that provides a natural 3-D view of an object or scene, dramatically increasing technical proficiency and the ability to interpret multidimensional data.
To produce stereoscopic graphics that both appear natural and are mathematically correct, you need to render stereo pairs using two asymmetrical-frustum perspective (also called offset perspective) projections with projection axes that are parallel to each other.
For stereoscopic graphics that are both compelling and comfortable, it is important to have enough stereoscopic interaxial separation, but not too much.

 Stereoscopic (3D Stereo) Pictures
Since this is a considerably greater distance apart than the eyes, the stereoscopic effect is no doubt exaggerated.
Adopt a comfortable 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 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).
