Panographies are wide-angle pictures composed of several individual photos manually stitched together. When these component photos are assembled, they give the impression one would get standing in one place, looking around and unconsciously putting the pictures together in one’s head.
This eliminates the frustration of not being able to capture the entire view/scene in one shot. However, the more shots you capture for a panography, the more time required to stitch them together. Nevertheless, it is well worth the effort. (via)
