Chân Dung Nam Đơn Sắc Tương Phản Cao Trong Studio

Ultra-detailed, high-contrast monochrome black-and-white portrait based on the reference photo. The subject's identity, facial bone structure, eye shape, nose proportions, jawline, hairline, and facial hair precisely match the reference photo, maintaining authentic skin texture, natural pores, and fine lines without smoothing. Subject & Expression: [A mature, confident man] looking directly into the camera with a serious, contemplative, and quietly authoritative expression; focused and introspective gaze. Pose: Classic "thinker" pose with one hand raised to the chin, thumb resting along the jawline, index finger slightly curled; knuckles, tendons, and hand skin texture in sharp focus. Lighting: Low-key fine-art studio lighting. Key light positioned slightly above eye level from the viewer's left angled downward, casting highlights on the forehead center, nose bridge, upper cheekbones, and top planes of the hand. Subtle shadow under the brow and cheekbones, controlled midtone detail on the shadow side, minimal front fill light, subtle rim light separating hair and shoulder. Small rectangular catchlights in the eyes. Background & Composition: Pitch-black background absorbing all light spill; tight vertical head-and-shoulders crop, centered composition.
