An amazing image of London, England, taken from the top of the BT Tower, has set a new record for the world’s largest panoramic photo. The image shows a full 360 degree view of London in incredible detail. Check it out here.
The 320 gigapixel image is made up of more than 48,000 individual frames. These were collated into a single panorama by a powerful workstation taking three months to process the resulting image.
If printed at normal photographic resolution, the panorama would be 98 meters across and 24 meters tall, almost as big as Buckingham Palace.
The photography firm 360Cities captured the images, with the team of Jeffrey Martin, Tom Mills and Holger Schulze doing the work, shooting all the images during the course of three days
In case you’re wondering, they used four Canon EOS 7D cameras with EF 400 mm f/2.8L IS II USM lenses and Extender EF 2x III teleconverters. These were mounted on Clauss Rodeon VR Head ST robotic panorama heads and positioned in four secure locations around the 29th floor platform of the BT Tower.
The panorama heads are capable of 72,000 steps in a single 360 degree arc, and in this case were set to fire four frames a second.
Laptops monitored a live preview of the progress of the shoot, which was accomplished in the teeth of sub-freezing temperatures and occasional 50 mph winds high above London.
The raw images were processed over a multi-week period using Fujitsu Technology Solutions’ Celsius R920 workstation with 256GB of RAM and 16 cores at 3.1GHz, and Autopano Giga panorama stitching software from Kolor.
The resulting online interactive version of the photo is presented in multi-layered, tiled resolution that permits zooming in to view extreme details, and is composed of millions of individual image tiles.
