Single Row Nodal Rotators
These nodal rotators are the simplest of them all, as all they do is hold the camera in place and rotate horizontally around the nodal point of the lens.
As most are adapatable to different cameras, they have systems to hold those in fixed positions as wanted. These means that the photographer needs to know the lens's nodal point position to manually adjust the device so that this is actually the point around which the whole system turns.
Warning : it is not easy to determine with presition the nodal point of any lens and it's even harder to get a camera precisely and firmly held in the right place, so it is advisable that once you are sure all the elements are togheter in the right position, you mark this with permanent markers on the hardware, so you can use these marks as references to reposition the elements the next time you need to assemble your set up.
Nodal rotators often have mechanisms that partially hinder the movement of the rotator in stops that guide to shoot consecutive images always rotating the same interval between shots.
A regular camera on a single row rotator can shoot a sequence of images that will stitch smootly and perfectly when editing the panorama. If the camera is regular enough, probably the picture, although covering 360 degree, will be of short height and therefore limited in its ability to create a truly immersive experience when navigated interactively. However, as we have seen, the cameras can have different lenses. The higher the amplitude of the lens, the smaller the number of shots required to cover the entire horizon, and also the greater the vertical viewing angle. To make the most of it it's worth to place the camera vertically as in portrait position.
The extreme case are the fisheye lenses, whith which a camera with the guidance of a nodal rotator can shoot an entire sphere in as low as two shots, although we always recommed to shot at least three.
Here is one of the best conceivable setups for spherical panorama shooting : single row nodal rotator + fisheye lens, camera and tripod.
