Fundamentals of stereophotography in medicine

Depth perception is given by binocular vision and it can be reproduced photographically by taking left and right pictures.

Important applications of stereophotography in medicine are examined in this article as well as some of the fundamental principles and techniques for taking 3-D pictures and viewing the results.
