The camera of a budget smartphone has become a way for many of the Rohingya stuck in Bangladesh’s refugee camps to tell their own stories, capturing photos of their lives in the camps, which became the world’s largest when 700,000 people fled the Myanmar military five years ago, joining 300,000 who had already sought refuge across the border. These photographers, who are all under 30, are building a record of the culture and traditions they fear could be lost so far from home, and have sharpened their skills during floods and fires and other all too frequent moments of crisis. Their photographs have featured in international media and photography competitions. Sahat Zia Hero, one of an increasing numbers of Rohingya photographers, last year published a book of his own work called Rohingyatography and has followed it up by helping set up a magazine that publishes the photos of others he meets in the camps.
