+ - 0 (“plus minus null”) is a facsimile of a unique, handmade artist’s book crafted by Volker Heinze in 1986. Its photos are the result of the young Heinze’s decision to radically capture the world around him—be it cityscapes, rooms casts in warm artificial light, friends or simply objects sitting on a table. Working against the removed perspective of documentary photography, Heinze employs color not as a tool of realism but with experimental flair, and plays with focus and the inevitable “mistakes” of analogue film—all to create an original aesthetic born from the idiosyncrasies of the photographic medium.
