Recently someone posted a link to a website where you can find lots of interesting 360 degrees panos. One wsa taken like during the fireworks at the Sydney Harbour bridge with tons of people in them.
How do you create a pano like that? How can you stitch the images together unless you have several cameras taking the picture but covering different angles at the same time.
You can tell 1 or 2 person not to move, but with that many people, I suppose it has to do with some computer wizardry?
