Step-by-step explanation:
The two common objectives of lighting design are visibility and focus.
Visibility refers to the ability to see clearly in a performance space. Lighting designers use different techniques to ensure that actors, objects, and key elements of the set can be seen by the audience. This includes positioning and directing light sources, using different intensities and angles of light, and creating contrast and highlights.
Focus is about directing the audience's attention to specific areas on stage. Lighting designers can use different lighting techniques and effects, such as shadows, to draw focus to particular actors or objects. By controlling light and shadows, they can guide the audience's gaze and enhance the storytelling and dramatic impact of a scene.
