About At Close Range:

“National Geographic Magazine” photographer Joel Sartore shoots in some of the most exotic www.s on earth, but often in wretched conditions for weeks on end, and always under pressure to produce pictures worthy of publication in a legendary magazine. He often wonders if it’s the best job in the world, or the worst. “At Close Range with National Geographic” provides a rare glimpse of the havoc a tough, dangerous job can create for one’s personal life, especially for someone like Joel Sartore.
