Create an ultra-realistic cinematic studio portrait of an adult man, framed from the upper chest upward, against a deep warm brown-to-black gradient background. If a reference photo is provided, use it as the only facial identity reference and preserve his exact facial features, natural skin tone, face shape, hairstyle, hairline, eyes, nose, lips, jawline, and realistic skin texture. Do not beautify, reshape, or alter his identity. Pose & Expression: The man faces mostly toward the camera with his head held upright, while his eyes look slightly upward and toward the side. Give him a calm, thoughtful, composed expression with closed relaxed lips. Keep the pose natural and sophisticated. Hair: Clean, neat low-cut haircut with a natural hairline and subtle taper. Very light, neatly groomed facial hair around the chin and upper lip. Wardrobe: Minimalist fitted black high-neck/turtleneck top with no visible branding. No necklace, no chain, no pendant, no earrings or distracting accessories. Lighting: Use dramatic low-key Rembrandt-style studio lighting. Illuminate only one side of the face with a strong warm amber/orange key light coming from the upper side, while allowing the opposite half of the face and body to fall into very deep, nearly black shadow. Create a sharp cinematic transition between light and darkness across the center of the face. Add subtle warm highlights to the forehead, cheekbone, nose, lips, and jawline. Background: Smooth seamless studio backdrop transitioning from pure black on the shadow side to rich burnt brown/amber on the illuminated side. No objects, patterns, text, or visual distractions. Photography Style: Premium fine-art editorial portrait photography, cinematic chiaroscuro, moody atmosphere, strong contrast, rich warm tones, realistic pores and natural skin texture, subtle catchlights in the eyes, controlled highlights, deep blacks, professional studio quality, shallow depth of field, crisp facial details, 85mm portrait lens look, f/2.8, high dynamic range, photorealistic. Composition: Vertical close-up portrait, subject positioned centrally, head and shoulders filling most of the frame, generous dark negative space on the shadow side, symmetrical visual balance, 3:4 aspect ratio.
