  "prompt": "A single 4x4 grid containing sixteen clean photographic portraits of the same male individual with medium skin tone, depicting their life from age 1 to age 151. The style must be a realistic, high-detail photographic study with steady, neutral lighting and a simple, neutral backdrop. The focus is strictly on the clear, progressive shift in age and physical detail across the life stages. MAINTAIN EXTREME CONSISTENCY in the individual's core facial structure, skin tone, and distinguishing general features (black hair, brown eyes) across all 16 portraits for immediate recognition.",
