World of stereoscopy
is a wonderful one. It not only gives us the 3-D sensation
as we live it normally, but it extends this 3-D sensation
to a new frontier. At the beginning of XXth century, photographic
development and research were important in
3-D applications, and much more photographers were
using it than nowadays and it was popular. 3-D images are
superb, gorgeous, and let us see things that we couldn't
capture with a normal picture, for example images of trees.
To-day, the image
technologies bring for sure many solutions, various
and efficient as much as the common rules are applied.

With the availability of
P&S digital compact cameras,
it is easier than ever to practice stereoscopic photography
cheap and simple. It only needs to be synchronized.
These pages are trying to explain
the important keys of this technique, and experienced people
should find new ways to practice it. Of course, it is successfully
applied to pole and kite aerial photography.
The evaluation of the stereoscopic ratio SR is very productive.
Rarely discussed, it is necessary for controlling the 3D
effect.
Forget the 1/30 rule, replace it
by the ISU rule D = B x F*
(in mm) and as much as possible use the calculator of this web site applying
the stereoscopic ratio which fit your images for nice 3D
rendering. 3D newby? Start with the page shot
