A group efford by Kolor, Arnaud Frich Photography, and Extraordinair-Urban robs former champion 360Cities of their “World’s Largest Panorama” title with a new massive 26-Gigapixel interactive panoram of Paris.  No normal camera could capture the detail they needed, so they constructed a custom rig:

Paris 26 Gigapixels was shot with very unique hardware: 2 Canon 5D Mark II (21.1 MP) each with a 300 mm f4.0 with a tele converter in order to get a  600mm /f8.0 needed to beat the record, mounted on a custom-made panoramic head.

The images were then stitched with the program Autopano Giga.

Browse around with the mouse and keyboard and marvel at the detail they’ve captured.  My favorite find so far is that you can actually see the individual people on the upper level of the Notre Dame Cathedral.
