The observation tower of János-hegy, the highest vantage point of Budapest with a 360 degree panorama. It also allowed them to take on previous world records in both the "highest definition image" and the "largest spherical panorama" category.
The World Record required a high definition Sony A900 25MP camera using a telephoto lens with an extremely narrow field of view. Fitted with a 400mm Minolta lens and 1,4X teleconverter, it provided a 2,4 degree horizontal FOW per frame. They estimated 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 would take a minimum of 6 hours to complete. (It actually took 20,000+ images over a course of a few days!)
