I always like the idea of 360˚ panoramic photographs. With nowadays technology, making a 360˚ photograph couldn't be easier. However, what about making of a 80 gigapixels 360˚ photograph?
Jeffrey Martin have been making panoramic photographs for long time. But this time the 80 gigapixels photograph is definitely astonishing, and we can see the details of the buildings in London. Perhaps Google should make a HD StreetView in its maps
