Couldnt a panormic be stitched Vertically AND horizontally? I would think panoramic is anything that is wider than the normal field of view attainable by a camera.. Especially if stitched.
That seems like kind of an odd definition to me. It would generally include fisheye shots of any aspect ratio, and exclude images shot with most (if not all) panoramic cameras, not to mention many stitched images shot with longer lenses (unless they contained dozens and dozens of images).
