XF105/305 White Paper
Stereoscopic 3D
BY TIM DASHWOOD
INTRODUCTION
Canon recently introduced ‘3D assist’ functions in the XF105 and XF305, making them the
fi
rst XF format cameras to include the features essential for professional stereoscopic 3D
production. This whitepaper will
fi
rst explain basic stereoscopic 3D concepts and rules for
beginners and then describe how to properly con
fi
gure a pair of XF105 or XF305 cameras
together for stereoscopic acquisition.
SECTION 1: THE BASICS OF 3D
The basic principle behind shooting stereoscopic
3D is to capture and then present two slightly
di
ff
erent points of view and let the viewer’s own
visual system determine stereoscopic depth.
It
sounds simple enough but the
fi
rst thing any
budding stereographer should learn is some basic
stereoscopic terminology.
These few terms may
seem daunting at
fi
rst but they will form the basis
of your stereoscopic knowledge.
TERMINOLOGY
Stereoscopic 3D a.k.a. “Stereo3D,” “S-3D,” or “S3D”
“3D” means di
ff
erent things to di
ff
erent people.
In the world of visual e
ff
ects it primarily refers to CGI
modeling.
This is why stereographers refer to the craft speci
fi
cally as “stereoscopic 3D” or simply
“S3D” to di
ff
erentiate it from 3D CGI.
Interaxial (a.k.a. “Stereo Base”) & Interocular (a.k.a. “i.o.”) separation
The
interocular
separation (or interpupulary distance) technically refers to the distance between the
centers of the human eyes.
This distance is typically accepted to be an average of 65mm (roughly 2.5
inches) for a male adult.
