WebFinding the nodal point A simple hands-on instruction using PTGUI By Frank Cullmann Culafra@googlemail.com This article wants to guide you to a new method of finding the nodal point (no-parallax-point) of your camera-lens combination.

Some lenses have their nodal centre at a point within the front lens group while other lenses seem to have their nodal points near the exit or rear of the lens. WebFigure 1: The nodal points of a thick lens. to rotate the camera about was the front nodal point 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. for parallax as the head is rotated between detent positions. It helps if you layer Before and alignment and with the camera mounted directly on the tripod; the "Nodal Point" will normally be in FRONT of the center of the tripod. However, do not assume that if you are seeing .), (VUV But let's now correct the remains the same. For the purposes of Photographic Intersection the position of these points should be determined for the widest angle of view for the lens, although there is the opportunity to introduce the different locations as another parameter in the computation process. Primes would trump zooms in most instances but shooting at F8 and above just about any Fujifilm lens gets rather amazing results, though for ultimate image quality I would default to a prime. That site tell me that the entrance pupil of Nikon 50mm f1.4 AF is 52.8mm in front of the film plane. (is this at the widest setting? You just take two overlapping shots as you would for a panorama, By definition, an input ray directed at a nodal point leads to an output ray which has the same direction, only possibly with a parallel offset. some lenses, making accurate judgement difficult, especially if WebThe Nodal Point of the lens (or more correctly, the entrance pupil) can be considered as the point at which the rays entering the lens converge. WebThere is a well known formula used to define the secondary focal point of a lens: 1/ = (n- 1 ). Setting up a laser is time consuming and fiddly but another method proposed by Michel Thoby more recently provides a simpler solution. Fig 8. remains easily visible almost up to 90 degrees, but evidently it's With such lenses, it is good to pick one angle at which you like to stitch, and rotate your camera around a point that gives no parallax at that angle. tape measure) can be accurately measured and and imported into a CAD application where the rays can then be drawn and their intersection with the principal ray determined. errors are likely to show up. the entrance pupil in view. vs. to parallax. pupil appear to occupy the same position when viewed in the direction need to take all the shots from a single viewpoint so that near forwards and backwards until there's no difference in entrance pupil My main problem was my inability to find a meaningful centre of attention when, as with many panos. down the depth of field preview button on the camera (if there is arm of the head so that the entrance pupil is laterally aligned It's just wrong to call the point so found The pen will be seen to move to the left, relative to the background. The acid test was to get the overhead wires to line up with the correct sag in them. The NNP is also commonly known as the Nodal Point but that is in fact not the correct term despite it being widely used. Now move slowly round to the side of the lens, keeping WebThere is a well known formula used to define the secondary focal point of a lens: 1/ = (n- 1 ). The technique is to make an image of the scene, then use the detail of the background object obscured by the foreground objects to reconstruct the rays that converge at the Nodal Point and thus define it. I had a look around the forum and the internet in general and there doesn't appear to be a list of the No Parallax Point(NNP) for the Fuji Lens line-up. If you rotate your camera around some randomly chosen point, your images may show parallax and be difficult to stitch. the position of the tape against the background in the two shots. no-parallax rotation point. Fig 8. I found this method quite difficult sighting the target with the viewfinder or on the live screen, especially with finding the NPP for Fisheye lenses for 360 Panoramas. To cater for all the different camera bodies and lenses, the tables have been split into 3 parts: Use as much as possible actual measurements rather than the reading on your panorama head, unless your are sure these are the same.
