Use the attached person exactly. Create a conceptual portrait where a perfectly vertical boundary divides the environment into daytime on the left and nighttime on the right.

The person's body straddles the boundary naturally while the face remains visible and receives a balanced neutral light.

Dress them in a sophisticated black outfit. Use an 85mm lens at f/3.2. Ensure the shadows, reflections and sky on each side behave according to their respective lighting conditions. Surreal but extremely controlled.
