Truly amazing photograph of Machu Picchu. Using an automated tripod head 1920 individual 18 megapixel photos were taken then stitched together to form one huge 16 Gigapixel Photo of Machu Picchu. http://www.gigapixelperu.com/Welcome.html It took 1 hour and 44 minutes to take the photos and 1.5 hours to stitch them together into the single massive image.
Video of taking the photo.
