By using intensity, colour, distribution, and movement, the designer can exploit the emotional and psychological effects inherent in light and thereby increase dramatic effect. The director is the overall leader of the production team and it is his or her vision that determines the overall artistic effect of a production. The lighting designer should be in on early discussions with the director and other department heads and must have read the script at least twice. These light the face of the actor and should be angled between 35 - 45 both horizontally and vertically. Low angles cause shadow from one actor to another.
High angles avoid actor-actor shadows.
These complete the modelling and separate the actor from the scenery. Rather, these are good principles and guidelines to follow with a flexible approach. Assume the beam to be 8' - 10' in diameter on the stage. Use two lights for each area, keeping in mind location and angles. Double or triple hang lights, if possible.
