What is the main feature of an open key light?

• A. The subject is looking towards the direction of the light
• B. The subject is looking away from the light
• C. The light is always diffuse
• D. The light is positioned behind the subject

Answer: (A)

Open key lighting is defined by placing the main light so the subject’s gaze is directed toward it. When the subject looks toward the light, the front of the face is lit and more of the facial features are visible to the camera, creating an open, approachable look with catchlights in the eyes and softer shadows on the near side of the face. This alignment between where the subject looks and where the light comes from is what gives the face its clear, readable shape. That’s why this option is best: it describes the lighting setup that makes the face appear open and directly lit. The other ideas describe different lighting moods—looking away or having the light behind would produce different effects like shadows on the front or a silhouette—while the light being diffuse is not the defining trait of an open key light, which can be either hard or soft depending on modifiers.
