In Believing is Seeing Academy Award-winning director Errol Morris turns his eye to the nature of truth in photography. In his inimitable style, Morris untangles the mysteries behind an eclectic range of documentary photographs, from the ambrotype of three children found clasped in the hands of an unknown soldier at Gettysburg to the indelible portraits of the WPA photography project. Each essay in the book presents the reader with a conundrum and investigates the relationship between photographs and the real world they supposedly record. With his keen sense of irony, skepticism, and humor, Morris reveals in this investigations how photographs can obscure as much as they reveal and how what we see is often determined by our beliefs.
