This course will be a review of the changing configurations of image-production devices, their invention, use and alteration. From the camera obscura, via the invention of photographic practices, to the institutions of film, broadcast television, video and the computer, images have apparently multiplied and spread. How do different uses of the screen affect us? How does the screen determine senses of space? What is a critical image practice which takes account of the dominant uses, by producers and viewers, of particular screens? Various critical image practices will therefore be assessed.
