Richard Mosse’s “Heat Maps”: A Military-Grade Camera Repurposed on the Migrant Trail – The New Yorker

In 2016, Mosse visited routes commonly travelled by refugees—from the Persian Gulf to Berlin, and from northern Niger to the now-cleared Jungle camp in Calais, France—and used a military-grade infrared camera to document scenes along the way.
