FINDING THE NO-PARALLAX POINT. Hold up a pen in front of you, close one eye, and focus your attention on the background scene as you move your head sideways from left to right.
The pen will be seen to move to the left, relative to the background. Like this: This apparent change in position of the near pen is an effect called parallax. It's plain to see that if you overlay these two photos to align corresponding features, you can either align the background features OR the pen. Panorama Stitching. Basics In the age of the digital image, panoramic photography is a technique of shooting multiple images of a single scene and combining them to form a single image with a wide field of view, from a relatively narrow capture of two to three frames along a horizontal to a deep zoom image composed of 30 frames, encompassing far more then the human eye’s natural field of view.
Panoramic images are distinguished from wide angle images by their aspect ratio. An image photographed with a wide angle lens may show a wide field of view (even 180º or more), but contain it within a standard 1:1.33 aspect ratio. Cha Dian.
