Chicago-based photojournalist KC Ortiz describes the focus of his work as casting a light on the world's forgotten and overlooked. His mission has taken him to remote regions throughout the Third World, where the common currency is hopelessness and violence. He's documented the Hmong insurgency in Laos and captured scenes of West Papua freedom fighters succumbing to the Indonesian military. His latest project, sponsored by clothing label LRG, took him to Puerto Rico, where he followed local graffiti artists Vizie, Steel and Omens -- members of the Mad Society Kings and Villains crew -- as they plied their trade in the crime-infested slums of Old San Juan's La Perla district. Ortiz's work there has been compiled in hardcover book form, with a limited run of just 50 copies, each hand-signed by Ortiz himself. Entitled Los Salvajes (The Wild Ones), the volume is comprised entirely of black and white photographs and bound in a stark white minimalist cover. It's available for purchase now directly through LRG.
