but there are a few problems, specifically with the setting of the “stereo window”- the method of using only parts of the picture that overlap will result in unnatural effects around the edges of the image- the fire hydrant, for instance, appears in front of the plane of the screen, but when our brain sees the bottom edge cut of by the frame of the picture, it tries to push it back into the plane, causing confusion. A program such as Stereo Photo Maker:

can set this “window” automatically.
I’d recommend reading Ferwerda’s “World of 3-D” as a good intro to the technical aspects of 3D.
