In this episode of Picture Perfect, VICE visits Patrick Brown in Bangkok to talk about the craft of photography and his forthcoming book, Trading to Extinction, which documents the illegal trade of endangered animals in Asia. We then travel with Brown to Guangzhou, China, where he finishes his decade-long project.
