Panoramic photography is a format of photography that aims to create images with exceptionally wie fields of view, but has also come to refer to any photograph that is cropped to a relatively wide aspect ratio (see Panoramic format) While there is no formal definition for the point at which "wide-angle" leaves off and "panoramic" begins, truly panoramic image are thought to capture a field of view comparable to, or greater than, that of the human eye - about 160° by 75° - and should do so while maintaining detail across the entire picture. The resulting images are panoramic, in that they offer an unobstructed or complete view of an area - often, but not necessarily, taking the form of a wide strip. A panoramic photograph is really defined by whether the image gives the viewer the appearance of a "panorama," regardless of any arbitrary technical definition.
