Key instructions to preserve
No beautification, no face reshaping, no expression change unless stated.
GuardrailFacial identity must survive the marble conversion — do not smooth away distinguishing features.
IDENTITY LOCK: Use the uploaded photo as the sole identity reference. Preserve the subject's facial structure, skin tone, eye shape, hairstyle, and every distinguishing feature exactly — the person must remain instantly recognizable. No beautification, no face reshaping, no expression change unless stated. SCENE: Subject rendered as a classical marble bust mounted on a rectangular plinth inside a grand natural history museum — spotlit in a darkened gallery hall. A small brass exhibition placard reads 'Unknown Figure, 21st Century, Extraordinary Rarity.' Two blurred museum visitors photograph the display from a respectful distance. PHYSICS & CRAFT: White Carrara marble texture with realistic subsurface micro-veining; the spotlight creates a single warm 3200K key from 45° above-left with soft edge falloff, a cool 4800K fill bounce from the gallery wall opposite, and deep shadow beneath the plinth. The subject's hair, collar, and top layer of clothing are fully translated into carved marble — every fold becomes sculpted stone. No color except the warm/cool light blend on white stone. TECHNICAL EXECUTION: 85mm lens, f/2.8, museum institutional photography style, ISO 400 fine grain, marble catches subtle lens flare from spotlight, polished plinth base reflects the underside of the bust softly. HARD CONSTRAINTS: Facial identity must survive the marble conversion — do not smooth away distinguishing features. Do not add a toga or costume. Do not alter the background beyond a dark gallery setting.
