Light, especially sunlight, is a tool which is easy to use and available for free. In collaboration with Michael Schultz we give an overview about techniques, present projects of artists working with light and experiment by ourselves. We involved scanning and copying machines to create interesting looks. Also colour filter, transparent paper and time exposure photography lead to surprising results. The whole look of the book works with neon yellow and blue. The blue refers to the old technique of Cyanotype, which we also tested in a chapter.
