With modern software I am wondering how important it is to work out the exact nodal point? In the panorama photography community, this special point is often called the "nodal point", but it is in fact unrelated to the actual nodal points of the lens.1,2 The actual nodal points are other points on the optical path, which are of no significance to most photographers. For some reason early on someone started to throw around nodal point and it stuck. However, when the camera isn't set at the nodal point and we're shooting a city landscape with numerous geometric lines as below, even the best panorama software can't do miracles!

If you try with other panorama software you'll see that they make the choice of a neat foreground but don't manage very well to align the background, in numerous cases. However, when the two images haven't been taken at the ideal rotation point, what happens next is unavoidable: either the software aligns the foreground of the two photos or either the background. With the 3D vision provided by your two eyes, it is easy to judge the approximate position of the bright spot: just move a finger along the lens barrel to a point where it seems to be the same distance away.

Nodal points and the eye Nodal points and the eye Author Michael J Simpson PMID: 35471355 DOI: 10.1364/AO.455464 Abstract Nodal points are defined using parallel object and image rays at very small angles to the optical axis, and Johann Listing described them when characterizing the eye in 1845.

Table 2: distance from C.N.D. In the frequently encountered situation where the refractive index is the same in front of and behind the optical system, the nodal points coincide with the principal points. Well if you rotate your camera "normally" around you to cover a panorama, you're getting pretty far from the ideal rotation point. the nodal point for a zoom lens is different at each zoom level. Preparatives I am assuming here that you are using a panorama head on tripod and that the camera is levelled all these points are critical! When it's about panoramic photography by stitching, you just need to rotate the camera around the entrance pupil and not the nodal point, that can by the way be really far depending on the lenses. 2 - The nodal point of the lens is now set just above the rotary axis of the head (on a "special" head called panoramic head) : We now place the nodal point of the lens just above the rotary axis of its special head, a panoramic head, and the alignment doesn't move! But historically, we started by talking about the nodal point and it's still very present in minds. ServiceNotices Two parallel diagonal lines on a Schengen passport stamp.
