Digital Light brings together artists, curators, technologists and media archaeologists to study the historical evolution of digital light-based technologies. It provides a critical account of the capacities and limitations of contemporary digital light-based technologies and techniques by tracing their genealogies and comparing them with their predecessor media. Including accounts by prominent artists and professionals, the collection emphasises the centrality of use and experimentation in the shaping of technological platforms. Contributions include considerations of image-oriented software and file formats; screen technologies; projection and urban screen surfaces; histories of computer graphics, 2D and 3D image editing software, photography and cinematic art; and transformations of light-based art resulting from the distributed architectures of the internet and the logic of the database. With essays by Alvy Ray Smith, Sean Cubitt, Terry Flaxton, Stephen Jones, Carolyn L. Kane, Scott McQuire, Daniel Palmer, Cathryn Vasseleu, Darren Tofts and Jon Ippolito.
