The Pulfrich Effect
The Pulfrich effect is named after Carl Pulfrich a German Astronomer. Although Carl Pulfrich was blind in one eye, he worked out that a 3D effect would be visible to most people under the following circumstances:
By placing a dark lens over one eye this slows down the speed with which the eye sees the image. Therefore in terms of movies and videos, while the other eye is seeing the current displayed video frame, the eye with the dark lens is only just seeing the previous frame. Effectively each eye will see a different frame. If the video is of a subject moving across the screen, each eye will see the subject in a different horizontal position relative to its surroundings. This creates a 3D illusion known as the Pulfrich effect, where the subject is perceived at a different depth to other objects around it.
To make the greatest use of the Pulfrich effect the camera should be constantly tracking or panning and having the subjects in the 3D movie constantly moving relative to the camera. The relative speed of the objects in relation to each other can also be used to increase the perception of depth.
The Pulfrich effect is especially popular with broadcast television as no special cameras are required, just some specialist knowledge. Also if the viewer does not have any Pulfrich 3D glasses they can still enjoy the video in normal 2D.
It is quite common to discover unintentional 3D effects while watching many sports or movies on television, for instance football players or racing cars moving across the screen or movie scenes involving travelling in a vehicle with the moving background visible behind the subject.
