TIME magazine recently released this interesting behind the scenes video showing the work behind its unique project to photograph a large panoramic image from the top of the One World Trade Center being built in Manhattan (in ground zero).
It took only 3 hours to complete but months to plan, is made of a series of about 1000 images shot from the top of the tallest skyscraper in the Western Hemisphere (the fourth-tallest in the world) using a 13-foot custom boom with a Gigapen robotic head and a Canon 5D MKII with a 100mm lens.
Despite being unique and extremely complicated to prepare, the TIME image is far from the highest resolution panorama around. This honor belongs to a gigantic 320 Gigapixel panorama of the city of London created in 2012 from the BT Tower in partnership with British Telecom to commemorate the Olympic summer of 2012.
You can see the panoramic image itself on the TIME website.
