Hotel Virtual Tour
A Virtual Tour (or Virtual Reality Tour) is a Visual Tour of a location composed of a varying degree of images that may be accompanied with sound or music. Tours may be comprised of photograph's,video,text,narration and sound effects or music. Generally, a virtual tour should evoke the sense of moving or walking through the location.More purposefully, they can be especially useful in Universities and the Real Estate industry where shoppers do not wish to visit each individual location. People browsing these Hotel Virtual Tours can often at least determine what they do not wish to see, eliminating several options so they may physically inspect ones that they know already interest them.- source - Wikipedia

Panoramic Photograpy
Panoramic photography is a style of photography that aims to create images with exceptionally wide fields of view, but has also come to refer to any photograph that is cropped to a relatively wide aspect ratio. 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.
