The record for the world’s largest panoramic photograph has been broken today by a new image, viewable online and captured from the top of the iconic BT Tower in London last year.

The 360-degree photo weighs in at a staggering 320 gigapixels and 48,640 individual frames, smashing the previous attempt in London – which captured a still impressive 80 gigapixels from Centrepoint in 2010.

The image, which offers a lot of grey clouds and miniature people commuting across town, was shot over a period of three days by Jeffrey Martin, Holger Schulze and Tom Mills, who work for a firm specializing in panoramic photography called 360Cities.

The pictures were shot using Canon EOS 7D cameras, with EF 400mm f/2.8 IS II USM lenses and Extender EF 2x III teleconverters operated by Rodeon VR Head ST robotic panorama heads from a firm called Clauss in Germany.

Simply processing the images took a further three months.

To get an idea of just how large this photograph is, if it was printed at normal resolution it would be 98 meters long and 23 meters high. In other words, almost as large as Buckingham Palace, or 60,000 times larger than a photo shot on the iPhone 4S.

You can look at the record-breaking panorama image over on the BT website right now.
