26-Gigapixel Photo Sets New World RecordCaptured in a series of 1655 images taken with a Canon EOS 5D Mark II camera, a man by the name of Holger Schulze captured a 26-Gigapixel photo of the cityscape in Dresden, Germany. The camera used a 400mm lens and was mounted on a motorized head to take the shots over nearly 3 hours.
The computer that processed the RAW image files had 16 processors and 48GB of memory. It took approximately 94 hours to stitch together all the shots into the massive 26-Gigapixel image.
