The Black Trilogy, a recent reissue of Ralph Gibson’s early self-published books, brings together three of his books into one volume. Gibson is credited with reimagining the modern photo book, transforming it from its more illustrative, thematic approach to a deeply personal, artistic form where the sequence is based on free association rather than chronology or narrative. By making available books that had, over the years, become hard to find, the trilogy offers an occasion to reexamine Gibson’s singular itinerary.
