At Harvard, the lighting designer is usually called upon to both create the conceptual lighting design and to implement the design in the actual space. This involves deciding which lights to use and where to place them in the theatre, which color gels and which effects to use in a show, as well as the practical knowledge of how to hang the lights and cue the show. Lighting designers may be responsible for hanging the lights and the more hands-on aspects of lighting a show as well as designing the various looks and deciding on schemes. Your design must take into account both the design of the set, the mood of the play, subtleties and dynamics in scenes within the play, and the blocking of the actors throughout. To light a show requires more than hanging lights or even deciding where to place them; the lighting designer must have a more-thorough understanding than most of the other designers, and must take into account the designs and vision of all of the other designers. In order to be successful, a show must have not only good direction and a nice set, but must a have a light scheme that shows both to their best advantage.
