Wikipedia reference to panoramic photography
describes panoramas as:
Panoramic photography is a technique of photography, usingspecialized equipment or software, that captures images withhorizontally elongated fields of view. It is sometimes known aswide format photography. The term has also been applied to aphotograph that is cropped to a relatively wide aspect ratio,like the familiar letterbox format in wide-screen video.
Segmented panoramas, also called stitched panoramas, are madeby joining multiple photographs with slightly overlapping fieldsof view to create a panoramic image, these images may not alwaysbe wide as they can be made into large blocks or done verticallyin what I refer to as a vertorama.
These are the traditional very wide panorama's, those panoramas that are just rectangular will be found mainly in the Block Style Panoramas section.
