partial images, for which, if needed, you can use the Cropping function in the
Media Pool (view page 140).
Note: The imaginary window is a type of a plane, behind which the 3D movie
plays. You select the closest, frontmost point. Not keeping up with this rule
can result in the object to "jump out" of the imaginary window, which when
used too much, can cause headaches.
 Maintain realistic eye angles: Object with a 3D depth effect viewed as a
red/cyan image (Anaglyph) without glasses will appear displaced. This
displacement should, if possible, take up less than 1/30 of the entire image.
Otherwise, it will appear that the eyes are looking in different directions.
Notice: Displacement may only occur along the horizontal axis. Displacements
on the vertical axis and rotated portions must be adjusted.
Record 3D
The distance between eyes in humans is ca. 65 mm, which forms the so-called
"stereo base width". But because our eyes are dynamic and we can even
"cross" our eyes, it is possible to focus on objects that are closer.
Various techniques exist for 3D recording. Each method has its advantages
and disadvantages:
 3D cameras with two lenses: The advantages are obvious; these cameras
produce 3D material without excessive work involved. The disadvantage is
that the stereo base width (lens distance) cannot be changed.
 Two cameras on a special mount: This involves a little more work. Two
cameras are mounted on a special support to record material for the left and
the right side of the 3D image simultaneously; microphone booms for stereo
recordings may also be used for this purpose.
The disadvantage in this case is that the shutter releases have to be pressed
at exactly the same time if there are moving objects in the picture. In case of
video, both movies must be synchronized before being edited.
Advantages: Stereo base width may be changed by adjusting the distance
between the cameras; larger selection of camera models.
 Two photos via the same camera: This technique only allows still images.
The camera is simply used to record two images from different perspectives,
and these are used as the right and left images. For best results, use a tripod.
