What is like to be on the front lines, armed with only a camera and surging adrenaline? Ron Haviv has 23 years worth of answers. The photojournalist’s work across 18 countries unfurls in “Testimony,” an exhibition on view through January 31 at New York’s Anastasia Photo gallery. “I believe and have dedicated my life to witnessing history in an attempt to create a body of evidence that holds people accountable,” Haviv has said. In this video, the first in a new series produced by the gallery, Haviv is joined by Sebastian Junger for a discussion about war, stories, pictures, emotions, and what happens when those things collide.
