Of course, Downeast Dimensions provides high quality stereoscopic viewers with all of its three-dimensional photography packages. But, for the purposes of this web-site, there is a technique called freeviewing, by which most people can learn to see a stereo pair of photos without the need of 3D viewers or glasses.
Here's how it works: Look at the stereo pair above. Relax your eyes. Don't try to look at the images; instead, try to look beyond them. Now slowly move toward the screen without focusing on the images until they double up. At some point, you will notice that it appears there are three images. The middle image should be in 3D. Try to hold that gaze and slowly back away until the middle image snaps into sharp focus. Voila! Or not. This will be easier for some than others. If at first you don't succeed, you could try again. Or other methods for learning to freeview may work better for you. Search for "freeview 3D" on the internet for alternate methods.

Stereography (3D photography) has been around since the early beginnings of the photographic arts. For several after the turn of the century, a trusty stereo viewer and a large assortment of stereo cards were common in middle and upperclass homes. With these in hand, families journeyed to the far reaches of the world, explored the wonders of their own country, experienced the horrors of wars and natural disasters, and learned about nature, science, and industry--all in the comfort of their own living rooms and parlors (and all with a sense of depth and realism still lacking in most forms of projected or broadcast entertainment).
The technique used is relatively simple: two photographic images are recorded at the same time of the same subject at slightly different angles. These slightly offset angles approximate the distance between the human eyes. When seen through a viewer that ensures that the left eye sees only the left view and the right eye sees only the right view, the brain sees the resulting image with all the depth of the original event.
