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.

Latin American and Latino artists have used photography to engage with modern media landscapes and critique globalized economies since the 1960s. But rarely are these artists considered leaders in discussions about the theory and scholarship of photography or included in conversations about the radical transformations of photography in the digital era. The Matter of Photography in the Americas presents the work of more than eighty artists working in Mexico, the Caribbean, Central America, South America, and Latino communities in the United States who all have played key roles in transforming the medium and critiquing its uses. Artists like Alfredo Jaar, Oscar Munoz, Ana Mendieta, and Teresa Margolles highlight photography's ability to move beyond the impulse simply to document the world at large. Instead, their work questions the relationship between representation and visibility. With nearly 200 full-color images, this book brings together drawings, prints, installations, photocopies, and three-dimensional objects in an investigation and critique of the development and artistic function of photography. Essays on key works and artists shed new light on the ways photographs are made and consumed. Pressing at the boundaries of what defines culturally specific, photography-centric artwork, this book looks at how artists from across the Americas work with and through photography as a critical tool.
