Summary:
Demonstrates the three basic considerations in controlled photographic lighting--placement of lights, quality of light, and lighting ratio. Uses a mannequin as a model to show the functions of main, fill, background, and accent lights in addition to the effects achieved when the lights are moved to different angles. Generalizes this studio set-up to apply to lighting in television, outdoor pictures, and when using flashbulbs. The effects of diffuse floodlights and spots are illustrated, and the changes produced by varying the lighting ratio is seen.
