As our eyes are positioned about 6 – 7 cm apart, there is a very
slight deviation between what we see with our right eye and
what we see with our left eye. The difference is processed by
our brain to produce a three-dimensional image. This principle is
applied to taking and viewing 3D pictures.
3D pictures can be viewed by the parallel method where the left
and right lines of vision are virtually parallel, as when looking at
a distant scene, or the cross method where the left and right
lines of vision are crossed, as when you cross your eyes. A cer-
tain amount of practice may be necessary to view 3D pictures
without using the viewer.
