A well adjusted system to its Pivot Point will ensure that the stitch software can fit all
the images into a final panorama without any problems.
How to adjust the Pivot Point for a specific camera/lens combination is explained in
countless very good descriptions in the “World Wide Web”.
In the World Wide Web many articles are misinterpreting the Pivot Point as the Nodal
Point.
1.5 Dead angle in Nadir
In the area to Nadir (-90°) the field of view is covered by the panorama head and the
tripod, thus called the dead angle in Nadir. Depending on the construction, each pano-
rama head has got its own specific dead angle. While rotating the camera to take the
pictures in the lowest row to Nadir, it is possible that parts of the lower row are hidden
by the panorama head. The covered parts are wasted (unusable) information. The
panorama calculator is able to correct this nuisance. The smaller the dead angle the
easier it is to cover each Nadir with a single picture. More about this issue later.
