What would you shoot with a Gigapan?
David Bergman chose the Olympics Opening Ceremonies.
"Photographer David Bergman created this Gigapan during the 2012 Olympic Games at Olympic Park in London, UK. He made the composite photo by shooting 425 individual photos in a grid pattern (25 across by 17 down) during a one-hour time period as the athletes entered the stadium. The final high-resolution image is 81,992 X 37,520 -- more than three billion pixels."
