### Full prompt
```text
A single 2x2 grid featuring the person from the reference photo in an identical close-up portrait across four professional studio lighting setups. Identity lock: identical facial features, calm neutral expression, hairstyle, dark top, head size, and camera angle across all panels—only the lighting changes. Shot with an 85mm lens look, sharp focus on the eyes, set against a seamless [medium gray] background. Top-left panel: Rembrandt lighting, key light at 45 degrees left and above, casting a small triangle of light on the shadowed cheek with moody falloff. Small white label below: "REMBRANDT". Top-right panel: Butterfly lighting, key light directly above camera axis, soft symmetrical shadow under the nose, beauty portrait glow. Small white label below: "BUTTERFLY". Bottom-left panel: Split lighting, key light directly from the side, one half of the face illuminated and the other in darkness. Small white label below: "SPLIT". Bottom-right panel: Rim lighting, key light directly behind subject edging hair and shoulders in bright outline, face lifted only by faint fill for near-silhouette drama. Small white label below: "RIM".
