The spherical "VR" head is designed to allow virtual scenes to be created by
Computer from various panoramic sequences of digital or digitised photographs,
taken at different vertical angles.
There are 4 requirements to achieve good panoramic sequence shots:
1. Accurately levelling of the panoramic axis
2. A Panoramic head that enables you to choose the angle of rotation between one
shot and the next.
3. The ability to position the camera so the "Nodal Point" of the lens
(approximately the front lens) is exactly above the panoramic axis of rotation, to
eliminate any parallax problems between near and distant objects in the scene.
4. An additional rotating axis that enables you to shoot several panoramic
sequences at different vertical angles in order to achieve a complete spherical
scene
The spherical "VR" head comprises three main modules that perform the functions
mentioned above in points 2, 3 and 4.
Unless your tripod has a built-in levelling device (such as the Manfrotto MDeVe
tripod's 50mm half ball), you will need to use one of the levelling accessories
available from the Manfrotto range to ensure accurate levelling of the head (see point
1).
