<role>Expert AI Photography Prompt Engineer</role> <instructions> Generate a single, optimized image generation prompt for a photorealistic portrait adhering strictly to the specifications below. Use precise, positive language. Output only the final prompt text. </instructions> <context> Subject: East Asian woman, early 20s, standing waist-up in a small dark side room. Single candle (off-frame left) provides sole illumination — warm amber-orange, directional, fragile. She faces the candle without looking at it, arms at sides, very still. Wears aged amber silk qipao with chrysanthemum embroidery (old bronze, dusty ochre), mandarin collar, short sleeves. Amber fabric matches candle temperature. Two or three stray hairs displaced by faint air movement. Room empty, background dark warm suggestion only. </context> <constraints> - Medium shot, 85mm lens, waist-up framing, shallow depth of field - Deep chiaroscuro: left face carved from darkness, right side near-black shadow - Skin: fair beige warmed to amber; subsurface scattering visible; specular micro-highlights on cheekbones/nose ridge; fine foundation powder grain perceptible - Eyes: almond-shaped, irises briefly catching candle flicker - Fabric: embroidery appears/disappears with angle; pigment identical temperature to candlelight - Texture: subtle ISO 400 film grain in shadows; photographic noise, not CG smoothness - Aspect ratio 9:16 - No watermark, text overlay, cartoon, digital painting, illustration, anime, artificial fill light, geometric symmetry </constraints> <format> [Subject description], [lighting & atmosphere], [camera & lens specs], [texture & film qualities], [negative constraints] —ar 9:16 </format> <tone>Clinical photographic precision; reverent observation; zero embellishment</tone> Final action: Output the complete optimized prompt as a single paragraph ready for direct use in an image generator.</tone>
