Viewing 3D Pictures by the Parallel Method and Cross Method
As our eyes are positioned about 6 cm or 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 certain amount of practice may be
necessary to view 3D pictures without using the viewer.
