What is the No Parallex Point?

www.ivamaui.com How to setup a Nodal Ninja Panorama head and rotate your camera on the No parallax Point. In relationship to photographing panoramas. If you shoot the same scene from a slightly different point of view, the foreground will be shifted in relation to the background, as in this example image. Parallax occurs in panoramic photography if camera and lens are not rotated around the Entrance pupil (or No parallax Point)of the lens. A difference caused by parallax will be visible in the overlap between two adjacent images. Parallax errors are sometimes very hard to retouch, since necessary background details might be obscured by foreground details. A useful way to fix these kinds of errors is to 'invent' some background details. If you shoot Panoramas at only infinity and do not include any foreground, than the No Parallax Point is not a concern, but if you want to include foregrounds, middle-grounds and backgrounds in your panorama than you need to use a Panorama head that rotates your camera around the No Parallax Point.
