Regardless of what you call the no-parallax point, it is easily found by trial and error. If you want something quicker you simply have to calibrate it for some different focal lengths that you think you will be using and mark them. The procedure is the same with primes and zoom lenses and it works in the field as long as you have two vertical reference lines to work with. Some lenses, notably fisheyes, do not have a single no-parallax point. Test bench limit exceeded (>350mm) at close focus, -335mm (Multiple internal vignetting locations), Nikon C8800 at Wide inf.

Here is the illustration of my words in a picture of example. Kalahari V2 head Note though that the longer the focal, the farer the nodal point; it's not always the case on more modern lenses, especially with wide-angle zoom lenses with retrofocus optical formulas. The entrance nodal point is thus different from the entrance pupil but it's around the entrance pupil you have to rotate the camera with the stitching method to get perfect overlaps. In these two photos we want to stitch to make a panorama, we just made sure to keep an overlap zone between the two photos in order to have a stitching zone. It seems like there should be an algorithm, but I haven't figured it out yet. If using a zoom lens for your panos, you'll need to determine the nodal points for all focal lengths you intend on using for your panos. Well if you rotate your camera "normally" around you to cover a panorama, you're getting pretty far from the ideal rotation point. I am planning to measure the nodal points for all the lenses (and there are some good references available online in regards to doing this), but thought I might first check if there is some sort of standard database on this somewhere - or perhaps if other forum members might contribute the measurements they use for these lenses here.

Set Camera to the connected camera. 36 For referencing purposes, the imaginary plane described above is set at the vertex of the concave surface of the lens, in order to quantify the angular distribution of the rays on the retinal surface. If you know where something like this is available for purchase, please post a reference, or link. Here's typically the type of stitching defects we may find with certain panorama software, in general less powerful because the most powerful among them can "erase" this type of stitching artefact (in Autopano Giga, it's a linear stitching, for the sake of education!). Photo filters "Entrance pupil" is correct although a bit imprecise to a geometry purist; it makes a good term for searching the literature and would be preferred in formal writing. We now place the nodal point of the lens just above the rotary axis of its special head, "Find the nodal point or no parallax point accurately in less than an hour" whether you are photographing a simple panorama or a 360 photo - PDF of 100 pages -, Texts and photos by Arnaud Frich - Copyright. Br), (XPF Shooting and stitching panoramas are easier with a nodal rail. When the software stitches two images, it looks for overlap zones common to the two images. By a system of adapted perpendicular stages, you'll have to place the camera on the head for its rotary axis and the nodal point to overlap. Definition: points of an optical system for which an incoming ray, directed at a nodal point, leaves the system with the same direction. To cater for all the different camera bodies and lenses, the tables have been split into 3 parts: The first table shows the position of the tripod mount in relation to the lens axis.
