Using the theme of Currency to invite reflection on the contemporary power of the photograph to relay and relate meaning across distance, the Triennial of Photography Hamburg explores the value of photography in the 21st century. The extension of this economic term to art and visual culture allows for a sustained engagement with photography and its relationship to value-making, canon-making, access, circulation, and knowledge production. At a time when the production, distribution, and consumption of photographic images has become ubiquitous and we have learned to structure our contemporary world through a lens, the digital image has become the currency of exchange on social platforms. Fostering interdisciplinary dialogue, the Critical Reader Lucid Knowledge: The Currency of the Photographic Image gathers international perspectives that reflect on how photography shapes today's narratives, as well as our perception and experience of the world.

The Estrangement Principle argues for a wider range of possible associations with art made by queer people by unraveling the difficulties of the "queer art" label. Goldberg invokes the lives and works of artists Renee Gladman, Jocelyn Saidenberg, Jack Waters & Peter Cramer, and others to bring into focus the problematics of categorization in art and literary histories. This book-length essay mixes cultural criticism, close readings, and personal anecdotes, all the while developing a deftly wrought tension between a polemical voice and one of ambivalence. The Estrangement Principle is an exercise in contradiction with the ultimate goal of resisting the practice of movement naming.
