### Full prompt
```text
Use the reference photo as the sole identity reference, preserving the subject's exact facial identity, facial proportions, hairstyle, beard pattern, skin texture, age, ethnicity, and natural features without beautification or redesign.

Fine-art black-and-white low-key studio portrait of the person.

Composition: Medium close-up framing filling approximately 65-70% of the frame, showing only the head, neck, shoulders, upper chest, and upper arms.

Wardrobe: The subject wears a [plain black fitted crew-neck T-shirt] with no logos or graphics.

Pose: Body rotated approximately 45 degrees away from camera in a [strong three-quarter pose], with the left shoulder closest to the camera. The chest faces toward the left frame. The head turns slightly farther left in a natural three-quarter angle, eyes gazing off-frame toward the upper left above eye level with a contemplative, introspective expression and slightly lowered chin.

Lighting: A [single soft key light positioned from the upper left] illuminates only the camera-facing side of the forehead, eye, cheekbone, nose bridge, lips, beard, and neck. The opposite side fades into deep shadow, with the far cheek, ear, jawline, shoulder, and body completely swallowed by darkness. The black shirt blends into the shadows.

Background and Style: Pure matte black background with no texture or distractions. High-contrast monochrome fine-art photography with soft shadow transitions, authentic skin pores, fine hair detail, and subtle film grain.
