The Complete Stereo Photographer
Stereo pictures have been around since the early
days of photography, when glass plates were being used. The technique has
not changed, and the idea behind it is very simple. We see in stereo by taking
the images from our right and left eyes, and mixing them. The brain determines
depth by comparing the amount of shift bettween various elements of a given
scene. The technical term for this shift, is paralax. it is generally thought
of as a nucance by photographers, and by sportsmen and snipers when adjusting
rifle scopes, in which case it is giving the unflatering label of paralax
error. The greater the paralax, the nearer the object. In theory, an object
at an infinate distance would show no paralax at all. In practice there is
a limit to the amount of shift our brains can percieve, but it is sometimes
amazing just how high this limit can be.
