Spherical Panorama From Non Aligned Shots
When we talk about creating Spheres from non aligned shots we mean those panoramas photographed with the help of multiple rows nodal rotators, which capture differently tilted pictures.
Perhaps the greatest utility of this type of rotators is that they allow for the camera to turn to the zenith and the nadir, ie, the extreme vertical positions. These rotators also allow for horizontal rotation around the nadir, so that in two consecutive shots it is possible to capture the entire background around it, leaving the rotator out on a side and the other in both consecutive shots.
To better take advantage of the best of each of these shots, before proceeding to the creation of the panorama, it is convenient to individually edit the nadir shots, cropping out of them the visible part of the nodal rotator. Let's see an example :
As it can be seen, the last two shots have been made with the camera pointing straight down, held in place by a nodal rotator which turns around it, occupying a great part of the images. If we create a panorama from the raw source images from the camera, it will look more or less as follows :
If instead of creating the panorama we delete the nodal rotator from the images we will work with, the resulting sphere will definitively be cleaner :
With all traces of the nodal rotator deleted from the scene, the resulting panorama spreads out much more. Compared with the previous example, in which the projection of the nodal rotator peeps in to almost a quarter of the panorama's height, the latest example looks much more open, being left out of it just a narrow strips at the nadir, which below we see painted black :
These area, which in the flat projection of the panorama seems to be very wide, spans indeed just a few degree. To check it out, click on the image. In the final panorama we can either leave this space as an empty spot or hide it behind an image or logo. From the next page we'll see step by step the process of a Spherical Panorama creation from non aligned shots, completed with a nadir cap.
