Hyper-Realistic Family Portrait with Identical Faces

Use the provided photo of one base person as the sole reference. Do not change the facial features, contours, part placement, expression, atmosphere, or identity of this person. All family members generated must share the face of the exact same person, and even if age, gender, or position differ, the facial characteristics must be completely identical. Maintain 100% fidelity to the face. Regardless of the number of people, compose all subjects into a single cohesive scene, finishing it as a professional, photorealistic family group photo. Express natural distance and positioning between family members, showing smooth group interaction. Adjust body size and height difference according to their respective settings, but ensure the faces remain completely identical. Use a unified color palette and style for everyone, and have them wear coordinated matching outfits. Express the body types of each person within a realistic range, without unnatural exaggeration. The background should be a dark, clean, professional studio background. Do not include unnecessary decorations. Lighting should be soft, studio-quality lighting. Emphasize realistic shadows, uniform and natural skin tones, and balanced contrast. Do not stylize, beautify, exaggerate, or reinterpret the face in any way. Maintain a strictly photorealistic, high-end portrait expression.
