What term is used to describe the manner in which lights are set up to illuminate the stage and actors?

The term that accurately describes the manner in which lights are set up to illuminate the stage and actors is "Stage Lighting Design." This term encompasses the overall planning and execution of the lighting strategy for a production, taking into account various factors like visibility, mood, focus, and the specific aesthetic desired for the performance. Stage lighting design involves not only the positioning of lights but also the choice of color, intensity, and type of fixtures used to create effects that enhance the storytelling and engage the audience.

In contrast, "Lighting Structure" and "Lighting Arrangement" do not convey the comprehensive and artistic aspects of lighting design. Additionally, while "Theatrical Illumination" describes the overall use of lighting in theatre, it is less focused on the intentional design process involved in crafting a specific lighting scheme for a particular performance. Therefore, "Stage Lighting Design" is the most precise and appropriate term for this context.
