According to Wired, Dan Woolley was shooting a documentary about the impact of poverty in Haiti when the earthquake struck.
He said that after being crushed by a pile of rubble, Woolley used his digital SLR to illuminate his surroundings and snap photos of the wreckage in search of a safe place. He hid in an elevator shaft, where he followed instructions from an iPhone first-aid app to fashion a bandage and tourniquet for his leg and to stop the bleeding from his head.
The iPhone warned Woolley not to fall asleep if he felt he was going into shock, so he set his alarm clock to go off every 20 minutes. We guess he didn’t have the battery to waste on listening to his extensive Coldplay collection or play games. The network was down so he couldn’t contact anyone.
He was saved 65 hours later by a French rescue team.
