On Jan. 12, 2010, one of the worst ever earthquakes in the western hemisphere left the Haitian capital of Port-au-Prince in ruins. Four months later, it was a vulnerable collection of jury-rigged tent cities, ill equipped to withstand the brutal rain and winds of the approaching hurricane season. Made of tree-branch poles and plastic sheeting, discarded canvas and corrugated cardboard, found metal and donated supplies, the tent metropolises were set up on hillsides, in front of the presidential palace and on the remains of houses and previous slums. They provided shelter for hundreds of thousands of people who no longer had a permanent place to call home.
TIME commissioned photographer Richard Mosse to explore the tent cities in May 2010. He shot with a wooden 8x10 camera, which conveyed the landscape of the tragedy in a very different way than the news photos that had come out of Haiti until that point.
