Shoot a scene, fully lit, in which two people are having a disagreement on any subject.For each shot, the producer should take production stills showing the setup, i.e. a good photo showing how each light source is positioned and gripped--a different crew should be able to completely reproduce the lighting using only these photos.  Submit these photos the day after the shoot.The purpose of the exercise is to create and control rather than to find light.  Look for reasonable space and great existing production design.  Light and block the actors so that they can move around naturally within the space.  Lighting should be motivated by practical and natural sources.  Within that framework, take advantage of as many characteristics and manipulations of light as possible. The camera can be moved, or not, as you wish.  Record and edit sync sound.
