Panoramic Photography (contd.)
	• The most common techniques in panoramic photography are "scanning" and "fixed lens". • With the scanning technique the lens is rotating around its rear nodal point (the optical point from which the focal length is measured) opposite a curved film plane. • This method gives a very wide angle of view, similar to that of the fisheye lens, but  without the extreme distortion of lines within the image. • In a fixed lens panoramic camera, a wide view angle is achieved optically by the lens.
