"I saw the light..."Sun, light, darkness, shadow--from time immemorial all weighted with significance and wonder. What mastery over nature, over others, to grasp the sun, control light itself! Know its speed, its colour, its radiation, its nature-is this not the power of the gods? Cinema is messaging with light and shadow. Figure and ground. Light, onto which we project significance, now transports our information. Perception shaped by our experiences, our interpretations, our projections, our illusions. Frames of drama and comedy, journalism and documentary, propaganda and advertising, all combined daily and edited, reproduced for mass consumption. What is the message?
