In his portraits of sex workers and the homeless struggling with addiction, photographer Chris Arnade is neither demanding an increase in social services or gawking from the sidelines at others' degradation. At their core, his "Faces of Addiction" portraits are simply about watching and listening to other people. Arnade repeatedly declares his one simple objective at the end of each detailed photo caption: "I post people's stories as they tell them to me. I am not a journalist. I don't try to verify, just listen."
