The Edge of Insanity

Earlier this week, internationally acclaimed photographer Joe McNally posted a heart-stopping photo to Instagram, saying:

�My old battered shoes climbed the worlds tallest building today. What an amazing structure! Tweeting from 820 meters straight up!�

The photograph was taken well above the observation deck (located on the 124th floor), this is literally the highest point on the planet a person can be, on a man-made structure.
Joe McNally�s career has spanned over 30 years with assignments in over 50 countries. He has shot cover stories for TIME, Newsweek, Fortune and The New York Times; been a contract photographer for Sports Illustrated, a staff photographer at LIFE and a 23-year (still ongoing) contributor to National Geographic. He�s fairly prolific on Twitter, and you can also find him online at his Blog, Facebook, Google+ and YouTube.
