I am not discussing the question of how to rotate the camera so that there is perfect stitching. This is an area I have never learned anything about. However, there is one interesting point. If a lens is distortion free (a theoretical ideal never fully realized), then the image of an item in left field should have the same perspective as if it were in the center by aiming the camera at it. So I surmise, that since lenses are not perfect re distortion, and small discrepancies would be apparent at a stitch, that there does exist a procedure that minimizes such effects. Am I making sense? >Bob, > >The perspective depends on where you are, not on the focal length of >the lens. There is a conception that a wide-angle lens produces an >exaggerated perspective.
