Jouko Lehtola is a Finnish photographer, born in Helsinki, and most widely known for his late-90s club series "Young Heroes." He is both angry and enthusiastic, and he excels at sussing out those same reactions in unexpected places--a tattooed biker sitting below a wall of gaily colored prize ribbons; kids in mohawks and girls with clownishly messy lipstick; men with sideburns and sunburns and two black eyes. Lehtola gets, it has been said, within smelling distance, and his viewers benefit.
