Cinema is a medium of light. And during Weimar Germany's advance to technological modernity, light - particularly the representational possibilities of electrical light - became the link between the cinema screen and the rapid changes that were transforming German life.In Frances Guerin's compelling history of German silent cinema of the 1920s, the innovative use of light is the pivot around which a new conception of a national cinema, and a national culture emerges. Guerin depicts a nocturnal Germany suffused with light - electric billboards, storefronts, police searchlights - and shows how this element of the mise-en-scene came to reflect both the opportunities and the anxieties surrounding modernity and democracy. Guerin's interpretations center on use of light in films such as Schatten (1923), Variete (1925), Metropolis (1926), and Der Golem (1920). In these films we see how light is the substance of image composition, the structuring device of the narrative, and the central thematic concern. This history relieves German films of the responsibility to explain the political and ideological instability of the period, an instability said to be the uncertain foundation of Nazism. In unlocking this dubious link, A Culture of Light redefines the field of German film scholarship.

We all have images that we find unwatchable, whether for ethical, political, or sensory and affective reasons. From news coverage of terror attacks to viral videos of police brutality, and from graphic horror films to transgressive artworks, many of the images in our media culture might strike us as unsuitable for viewing. Yet what does it mean to proclaim something “unwatchable”: disturbing, revolting, poor, tedious, or literally inaccessible?
 
With over 50 original essays by leading scholars, artists, critics, and curators, this is the first book to trace the “unwatchable” across our contemporary media environment, in which viewers encounter difficult content on various screens and platforms. Appealing to a broad academic and general readership, the volume offers multidisciplinary approaches to the vast array of troubling images that circulate in global visual culture.
