Since the early 19th century and the invention of photography, artists have been experimenting with various methods for creating photographs without a camera. At once exhaustive and compelling, this book reveals the myriad approaches artists have used to create photographic images using just paper and a source of radiation. Simultaneously a chronological history and a thematic study, this book explores a range of practices, some of which have been in use for more than a century, while others are entirely contemporary. From placing objects on light-sensitive paper and drawing on blackened glass plates to radiography, photocopying, and digital scanning, this is an elemental kind of photography that repudiates the idea that technology advances in only one direction. By eliminating the camera, artists are able to focus on other ways of making photographic pictures. They allow the world to leave its own imprint, to speak for itself as itself. This volume includes 160 exquisitely reproduced works of this kind. In turns abstract and realist, haunting and intricate, they seem to capture the very essence of their subjects. Featuring artists from the 19th century to today, this book explores cameraless photography as an important and influential medium that deserves to be included at the forefront of today's conversations about contemporary art.
