"Callahan's work embodies thirty-five years of investigation into the expressive and structural potential of photography--an investigation that has been both uncompromisingly rigorous and intensely personal. HIs photographs reproduced here in the most complete selection ever published, reveal new dimensions of the medium's creative possibilities. Whether photographing his family, pedestrians on Chicago streets, or the beaches of Cape Cod, his vision has always been precise, defining the subject, and culminating with images of eloquent strength and balance."--book jacket.
