Get lost in a stunning 320-gigapixel image of London

How well do you know the landmarks of London? Get up close and personal with a stunning 320-gigapixel image of the city captured atop the BT Tower.

Snapped by panorama experts 360Cities, the epic photography endeavor required the use of four Canon 7D dSLR cameras outfitted with some heavy-duty equipment.

Each camera used an EF 400mm f/2.8L IS II USM lens, Extender EF 2x III teleconverter, and a Rodeon VR Head ST robotic panorama head. After shooting 48,640 individual pictures over the course of three days (shortly after the 2012 Olympics), 360Cities spent the next several months assembling and stitching together the final gargantuan image.

To access the larger-than-life 360-degree panorama of London, simply click here or use the embedded panorama above. You can easily spot many familiars such as The Shard, London Eye, and Tower Bridge once you get moving.

You'll quickly notice that it's easy to clearly see nearly anything (or anyone) located many miles from the BT Tower. You almost feel like Big Brother after five minutes of looking. Pro tip: for maximum zoom, keep hitting the plus zoom button. Even if the slider bar indicates you've gone all the way you can actually go farther.

If printed out on paper, the 320-gigapixel super shot would stretch out 323 feet wide and stand 77 feet tall -- nearly the same size as Buckingham Palace. I wonder how much that frame would cost.
