Adam Krause photographs Brooklyn skinheads in his series, “Greenpoint Brooklyn Nazi Skinheads.”

Photographer Adam Krause was at his local gym when he first met the guys who’d become the subjects of his series “Greenpoint Brooklyn Nazi Skinheads.” Krause grew up in Florida and was part of a tough punk rock community himself. “I knew the guys were skinheads after recognizing a racist band on one of their T-shirts. I think my background of being involved in the punk scene just helped me identify these guys, similar to someone interested in cars probably can identify a certain model of car,” he said in an email.
