3. Requirements for a good panoramic image
The panorama head was developed to enable the creation of virtual scenes
with a computer by means of various sequences of digital photos or digitised
photos, which are captured from various vertical angles .
For a good panoramic sequence, four basic requirements are necessary:
1 . Precise levelling of the panoramic axis .
2 . A panorama head that gives you the choice of rotation angle between one
frame and the next .
3 . The ability to mount the camera so that the nodal point of the crystalline
lens (front lens) lies exactly above the panoramic rotation axis and in this
way parallax errors between near and distant objects in the scene are
avoided .
4 . An additional rotational axis that makes it possible to capture various
panorama sequences from different vertical angles resulting in a complete
spherical image .
The panorama head consists of three main modules which perform the above
functions, and their guide rails are equipped with spirit levels .
