In the early Eighties, a community of male prostitutes and transvestites lived and worked in brothels in the Chilean cities of Santiago and Talca in order to avoid life-threatening brutality from a merciless military regime. Their stories might have remained hidden if not for the work of Chilean photographer Paz Errázuriz. Self-taught, Errázuriz began photographing invisible communities and cultures in the 1970s. In collaboration with journalist Claudia Donoso, she recorded the lives of these individuals and put their stories in a book titled La Manzana de Adán (Adam’s Apple). Now, many of the photographs and texts from the book are on view at BAM/PFA (2626 Bancroft Way, Berkeley) in the exhibit Paz Errázuriz / Matrix 251. The black-and-white photographs are tremendously affecting, offering a glimpse of fragile lifestyles of alienation made beautiful with the means available. In one series of three photographs a sex worker named Coral is shown undressing, only wearing a garter and pantyhose, in front of a rundown building that has the texture of a smoky hearth. The photo is intimate and yet not intrusive or judgmental, allowing for a perspective that has rarely been given a public venue.
