The perfect alignement, pixel-wise, of cameras, is crucial for the comfort of your audience. The slightest vertical parallax must be eliminated, because it would force one eye to look up while the other look down. Various other elements can lead to other painful, disturbing or tiring vertical disparities: text/html 2010-12-14T10:01:30-05:00 http://www.convergence3d.net/en/and_if_you_re_discovering_stereo3d_you_better_start_here?rev=1292342490&do=diff You'll find here the basics that are necessary to understand all the rest of Convergence3D... Principles Shooting stereo is shooting to recreate on screen the feeling of depth the brain gives us in reality, using the small difference of point of view between the right eye and the left eye.

For example, the artificial horizon of a 6.5m/21ft-wide screen is +1%, because 1% leads to a screen offset of 6.5cm/2.5in.

It can be changed on most 3D-rigs. It is very often mistakenly called ”Interocular” (or I/O) - which is the distance between the eye (average: 6.5cm/2.5in). The interaxial is different of the interocular on most shots (smaller in most cases, except for large landscape shots).

It is possible to imagine scenes where the drama will be amplified if one plays with depth, the out-of-screen effects, or the effects of giganticism and miniaturization.
