Well, that is not completely true, the image on your left is zoomed in on the actual image which is an amazing 15.9 gigapixels (one gigapixel is equivalent to 1000 megapixels).
The image its self is actually made up of 1920 separate pictures taken with a robotic mount on a Canon 7D with a 400mm lens. Those photos have been stitched together and the end product was amazing!
The photographer, Jeff Cremer says “In 2008, the World Monuments Fund placed Machu Picchu on its Watch List of the 100 Most Endangered Sites in the world due to environmental degradation mostly from tourism. So, I believed that this extraordinary site deserved a remarkable photo to hopefully raise awareness and help in its preservation.”
