Hyper-Detailed Structured Prompt for High-Fidelity Portrait Generation
A highly structured, JSON-based prompt designed for Gemini 3.0 Nano Banana Pro, focusing on generating a high-fidelity portrait. It specifies extreme detail levels (pore-level skin detail, absolute biological consistency), complex wardrobe physics (sheer knit with crystalline glitter), a specific pose (rotated head over shoulder), and detailed environmental and optical rendering settings (85mm prime lens, f/2.8 aperture, overcast lighting).
