Black and white studio portrait of a four-member family standing in a line, hands overlapping, centered.

STRICTLY preserve the appearance of all four 1:1 — faces, features, proportions, age, skin texture, hair length and color, without retouching or smoothing; the photo is the only reference. Black and white studio portrait, 3:4 aspect ratio, vertical symmetrical composition. There are four people in the frame, aligned strictly in the center in a single vertical line. At the bottom — the youngest child, in the center, looking directly at the camera, light natural smile. Above the child — an older child, positioned right behind them, both hands gently resting on the crown of the younger child's head, fingers intertwined, soft lively smile. Above them, a woman — both hands gently resting on the crown of the older child's head, fingers intertwined, soft lively smile. At the top — a man, standing behind the woman, both palms folded and gently resting on her head, fingers intertwined, looking directly at the camera, calm and confident facial expression. Everyone is wearing identical black turtlenecks without decorations. Background — completely black, without texture. The light is soft, directed from the front and slightly from above, sculptural, moderate contrast, crisp skin detailing, no glossy effect, without changing poses or distances. Hyperrealism, 8K.
