The no-parallax point is also the "center of perspective", but this term is not commonly used and does not describe why the no-parallax point is important.

Most higher-end image editing programs now feature automated panorama stitching, but if you don't rotate the lens on its nodal point while capturing the individual images for your spherical panorama, even the best image editing programs will find it challenging to stitch all of the images perfectly. With modern software I am wondering how important it is to work out the exact nodal point? Liveview mode makes it simpler than ever. 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.

If you rotate your camera around some randomly chosen point, your images may show parallax and be difficult to stitch. PN 1 and 2 = Nodal Point 1 and 2 - AdeR = Axis of rotation. As far as they get accepted by the author, they will appear above this paragraph together with the authors answer. My particular pano rig consists of a bidirectional clamp and a multi-purpose rail. Remember to use my links when you shop on these sites! By trial and error I found that the OM 50mm lens on an E-520 sits with the front of the lens roughly over the centre of the tripod head and the 11-22mm sits near the front of the focus ring when at 22mm. It's even really simple because it's done with the LCD screen or the viewfinder of the camera if it's a reflex as we'll see in the page dedicated to the entrance pupil!

I'll stress again, but I already explained why above, that the less you shoot close subjects, hence beautiful and distant skylines, the less the problem of the nodal point (of the entrance pupil) is raised. PhotoTips&Stories
Well, it's no big issue and in the facts, whether you talk about nodal point or entrance pupil, it's the ideal rotation point and that's the most important. In panoramic photography by stitching, it's important that two consecutive images are shot from the same point of view to overlap well when stitching.

No matter how well the vertical lines line up the images always had the lines barreling up instead of sagging. 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. It doesn't cost you anything and it's a win-win deal for me, them, and you! You don't want to "stupidly" put your camera on a classic head but rotate it around an "ideal" rotation point that is located somewhere in the lens and not below the camera. endobj

In the previous page, we saw that it's better to rotate the camera around an ideal rotation point, the entrance pupil (wrongly called nodal point), in order to guarantee perfect stitchings (if the lens doesn't have complex distortions however or if we use the best panorama software on the market). Panoramic heads Varies: 41.2 (0) to 57mm (100), Nikkor AF DX 10.5mm f2.8G ED (Shaved, edge Null), ~47.5mm recommended on FX cameras. ), (NIO --, As with all creative work, the craft must be adequate for the demands of expression.

Record the position of the nodal rail in your clamp, such as "Clamp centered on 49mm rail mark," the lens being used and (if using a zoom lens) the focal length setting of the lens. To calculate the Entrance pupil distance add the Tripod Mount Length (L1) from the camera and the Entrance Pupil Length (L2) from the lens. One needs two vertical objects as reference points, like a street lamp post 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.
