Final answer:
Key, fill, and back light are different lighting techniques used in the creation of photographs and stage lighting to illuminate the subject, manage shadows, and control the mood and focus of a scene.The correct option is b.
Step-by-step explanation:
The words key, fill, and back light describe different types of lighting techniques used in photography and stage lighting. Key light is the primary light source that illuminates the subject; fill light is used to reduce shadows caused by the key light, creating a more balanced lighting; and back light shines from behind the subject often to create a silhouette or to separate the subject from the background.
In the case of a backlit subject, the use of fill flash can correct the issue by adding light to the front of the subject, balancing the bright background.When a lighting designer is working in a theatre environment, key and fill lights, along with back lights, are used to create a sense of realism, focus attention, and enhance the storytelling aspect by controlling the visibility and mood on stage.The correct option is b.
