On a roof of the "Haus der Presse" http://commons.wikimedia.org/wiki/Category:Haus_der_Presse,_Dresden [House of Journalism] building in Dresden, Germany, representatives of A.F.B. media placed a Canon EOS-5D Mk II digital camera equipped with a 400mm lens on a robotic arm. That Robot took pictures of a Dresden panorama for 172 minutes straight, resulting in 1,665 photos. Each photo contained 21.4 Megapixels of data [by default, EOS-5D gives out 21Mpixel image i.e. 5616 x 3744 pixels - but A.F.B. media GmbH used almost all of 22Mpixels thanks to Full-Frame sensor, Ed.].The end result was 102 GB of images, stitched together on a heavy-duty quad-socket workstation packing 16 processing cores and 48 GB of memory. For this daunting task, it took 92 hours of full 100% CPU load across all cores but the result of this is a staggering image in a majestic 297,500 x 87,500 pixel resolution – 26 Gigapixels.
According to claims by both A.F.B. media GmbH and Sachische Zeitung, this image is the biggest picture ever. You can see this photo on the project’s web page. We must say that this is one VERY IMPRESSIVE image.
