The stereoscopic cinema has become, once again, a hot topic in the film production. For filmmakers to be successful in
this field, a technical background in the principles of binocular perception and how our brain interprets the incoming data
from our eyes, are fundamental. It is also paramount for a stereoscopic production to adhere certain rules for comfort and
There is an immense variety of options in the art of standard "flat" photography, and the possibilities only can be
multiply with the stereo. The stereoscopic imaging has its own unique areas for subjective, original and creative control
that allow an incredible range of possible combinations by working inside the standards, and in some cases on the
boundaries of the basic stereo rules.
The stereoscopic imaging can be approached in a "flat" manner, like channeling sound through an audio equalizer with
all the bands at the same level. It can provide a realistic perception, which in many cases can be sufficient, thanks to the
rock-solid viewing inherent to the stereoscopic image, but there are many more possibilities.
This document describes some of the basic operating parameters and concepts for stereoscopic imaging, but it also offers
ideas for a creative process based on the variation and combination of these basic parameters, which can lead into a truly
innovative and original viewing experience.
This paper shortly describes part of the experience gathered in more than 10 years of stereoscopic movie production, some of the most common problems found and the solutions, with more or less fortune, we applied to solve those problems. Our work is mainly focused in the entertainment market, theme parks, museums, and other cultural related locations and events. In our movies, we have been forced to develop our own devices to permit correct stereo shooting (stereoscopic rigs) or stereo monitoring (real-time), and to solve problems found with conventional film editing, compositing and postproduction software. Here, we discuss stereo lighting, monitoring, special effects, image integration (using dummies and more), stereo-camera parameters, and other general 3-D movie production aspects.
