Thanks for posting that.
100 years ago, panoramic cameras were complex mechanical devices. They rotated, like clocks,
threading long, very wide negatives through a small crack that turned with the camera. Essentially, they took a small section of a time, and kept moving. Consequently, there are old photographs in which people appear two or three times in pne photograph. The camera would rotate past, then they would run around behind, and stand again in a place it had not yet covered.
New technology is much different. There are programs which marry digital images, and a new one that does the same with many, many tightly zoomed shots, allowing a great deal of detail.
