Panorama de Lisbon
Panorama In its most general sense, a panorama is any wide view of a physical space. It has also come to refer to a wide-angle representation of such a view whether in painting, drawing, photography, film/video, or a three-dimensional model. Further, the motion-picture term, pan or panning, is derived from "panorama". A panoramic photograph. This image shows the curved edges of each segment of the panorama which are due to the warping of the image to conform to the cylindrical projection used to present such a wide angle of view. These edges would normally be cropped so the image can be displayed in a more aesthetically pleasing manner The word was originally coined by the Irish painter Robert Barker to describe his panoramic paintings of Edinburgh. Shown on a cylindrical surface and viewed from the inside, they were exhibited in London in 1792 as "The Panorama". Panoramic photography soon came to displace painting as the most common method for creating wide views. Not long after the introduction of the Daguerreotype in 1839, photographers began assembling multiple images of a view into a single wide image. In the late 19th century, panoramic cameras using curved film holders employed clockwork drives to scan a line image in an arc to create an image over almost 180 degrees. Digital photography of the late twentieth century greatly simplified this assembly process, which is now known as image stitching. Such stitched images may even be fashioned into crude virtual reality movies, using one of many technologies such as Apple Computer's QuickTime VR or Java. A rotating line camera such as the Panoscan allows the capture of very high resolution panoramic images and eliminates the need for image stitching. On rare occasions, panoramic, 360° movies have been constructed for specially designed display spaces typically at theme parks, world's fairs, and museums. . Panoramic systems that are less than 360° around also exist. For example, Cinerama used a curved screen and IMAX movies are projected on a dome above the spectators.
