Preserve the exact facial features, proportions, and identity from the reference image. Do not change the face shape, eyes, nose, mouth, skin texture, or facial expression. Preserve the identity from the reference image. The face must match the reference image 1:1. [FRAMING AND CAMERA ANGLE] Waist-up shot, vertical format. Camera at chest level, slightly angled upward from below. 85mm lens, f/1.8 aperture. The figure is shifted to the left; the right half of the frame is deep darkness. [POSE — EACH BODY PART SEPARATELY] The torso is turned 45 degrees to the right from the camera — the right shoulder is closer to the lens, while the left recedes into shadow. The head is turned back over the left shoulder — the gaze is directed upward and to the side, past the camera. Facial expression: thoughtful, serious, with slight tension. Lips closed firmly, without strain. The right arm hangs down along the thigh — the hand is tucked into the trouser pocket, with the thumb outside. The left arm hangs alongside the body, outside the frame. Shoulders broad and squared, with the shoulder and neck muscles visible beneath the shirt fabric. Torso straight and confident, with pronounced torso volume. [CLOTHING — SEPARATE BLOCK] Short-sleeved polo shirt — dense piqué knit, dark gray, almost anthracite, with a matte texture. Stand collar with two buttons, both fastened. Fitted cut, emphasizing the volume of the shoulders and torso. Sleeves tightly encircle the biceps — the fabric is stretched over the muscles. Light beige or khaki trousers — dense cotton twill, straight cut, waistband with belt loops. Barely visible at the lower edge of the frame. [JEWELRY AND ACCESSORIES] No jewelry. No accessories. [BACKGROUND — PRECISE AND DETAILED] An absolutely dark background — deep black, velvety, without texture or details. No objects, walls, or textures — pure darkness. The figure emerges from the darkness; the entire left half of the body is completely swallowed by shadow and merges with the background. The distance to the background is impossible to determine — it is infinite. [LIGHTING — LIFELIKE AND DETAILED] A single light source — a narrow, directional light from the front-right, sharp and high-contrast. The direction is from the side at a slight angle from above. Neutral, slightly cool tone. The light is hard, with a distinct boundary between the illuminated and shadowed sides of the face. The right side of the face, neck, shoulder, and arm is brightly illuminated. The left side is in deep, impenetrable shadow. Sharp highlights on the cheekbone, bridge of the nose, forehead, upper lip, shoulder, and bicep. Shadows are deep and dramatic, with clearly defined edges. [COLOR GRADING] Cool, neutral color grading. High, harsh contrast. Shadows are absolutely black, without detail. Illuminated areas are clean, without overexposure. The dark-gray polo recedes into shadow, retaining texture only on the illuminated side. Kodak Tri-X 400 film — pronounced, organic grain, especially in the shadows and dark background. [TECHNICAL PARAMETERS] Capture: 85mm, f/1.8, RAW, photorealism without retouching. Style: High-Contrast Dramatic Studio Portrait, Hard Side Light, Film Grain Realism. –ar 9:16
