My Brothers, Our Sisters, is a new photography exhibit at the Flagstaff Medical Center. It centers on the work of the Northern Arizona Volunteer Medical Corps in Haiti, a country hit hard over the last decade by natural disasters. The photos depict the lives of Haitian hospital workers, patients and children. They were taken by Flagstaff-based photographers, Jake Bacon and Michael Collier, who is also a doctor. This morning/today, they talk about the responsibility that comes with taking photos of tragedy.
