The world's largest digital photograph is now a 70 gigapixel panorama of Budapest taken by 360World. It has beat the 45 gigapixel image of Dubai and the 26 gigapixel image of Paris for the title.

"The World Record starts with a high definition camera and and a telephoto lens with an extremely narrow field of view. Sony’s A900 25MP camera seemed an obvious choice, and Sony was pleasantly eager to provide us one. Fitted with a 400mm Minolta lens and 1,4X teleconverter, it provided a 2,4 degree horizontal FOW per frame. Our estimate was that a 60 gigapixel image (with the necessary overlaps) would require 5040 individual photographs — 24 rows with 210 frames in each, taken with a 360 degree horizontal and a 60 degree vertical FOV. Counting with 4 seconds per frame (during which the robotic head re-adjusts for the next shot), it was quite clear that the task would take a minimum of 6 hours to complete. "
