Easy Aerial Stereo 3D shooting

2D for 3D – or – The Pulfrich effect.

Shooting 2D for 3D will probably become industry terminology soon enough, just as ‘shooting dry for wet’ or shooting day for night are already established practices in modern film making.

Thanks to a certain scientist, Carl Pulfrich, who demonstrated the phenomenon also know as time multiplex in stereoscopic 3D circles, this trick of the trade has been used to some degree in the past by stereographers who know how to work within the limitations of this technique.

In very basic terms, if a subject is shot with a camera in steady orbit around it, at any given point in time there will always be a unique view-point of the subject recorded by the camera. This is also true if the camera is stationary and the subject itself is rotating. Using the time-multiplex (pulfrich) principle, two unique views can be extracted from such a scene, that will offer the two needed viewpoints as seen or recorded by typical stereoscopic 3D cameras.

The method to extract the second viewpoint is to use …
