Light Image Imagination is an anthology of text- and image-essays by international scholars and artists who lead critical discourses in audio-visual media history, practice and theory. The main focus of the contributions lies in discourses and topics around 19th and 20th century innovations in arts, media and technology, and their media-archaeological and philosophical foundations. It juxtaposes text and image-essays to stimulate dialogue and associative interconnections in order to discuss the creation, perception and projection of images (both mental and material) and their specific relationship with light and imagination. A key feature of both the individual contributions and the book as a whole is that disciplinary boundaries are challenged in order to amplify and enrich the thinking about mediated images. The anthology is accessible to a broad readership and will appeal especially to a constituency that views the boundaries between science, art and technology as a permeable and exciting territory to explore. The contributing authors and artists work at the interdisciplinary intersections of the Arts, Sciences and Humanities. Their expertise includes film and media theory, media archaeology, cinema history and theory, philosophy, history of science and technology, astronomy, computer music, literature studies, neuroscience, psychology, art history, art practice (painting, photography, film, video, digital arts; music composition).
