ABSTRACT
The screen space is created by the interaction of the 2D screen and our eyes, and can be somewhat transformed using very specific visual effects. Setting this value is an artistic and technical decision linked to lens choice, desired 3D effect. A perfect way to experience the effect of changing interocular distance is to take a set of pictures of a landscape. They will show no 3D disparity at all, for the interocular distance has no effect on their images. The key factor in its effectiveness is to avoid hitting the top edge of the screen; this is most likely because we are used to seeing the heads, but not the feet, of people standing in front of us. 3D cinematography affects the whole production process, from project submission to exhibition. The industry needs to define and agree on a couple of new conceptual tools and the adequate vocabulary to communicate them among crewmembers.
