Use the attached model. Create a conceptual studio portrait where a glass prism projects a subtle spectrum of natural light across one cheek and the background.

Dress the subject in minimalist dark clothing. Face clearly visible.

Use an 85mm lens at f/3.2 and strong natural sunlight entering from camera-right. Keep the prism effect subtle and physically realistic, with actual refraction rather than painted rainbow colors. Preserve natural skin pores and eye detail.
