Nano Banana 企业肖像

A highly structured JSON prompt for the Nano Banana Pro model on Gemini, designed to generate a photorealistic, high-end corporate portrait of a generic adult male. It specifies detailed scene, subject, outfit, camera settings, and includes strict negative prompts to avoid celebrity likeness and maintain a professional studio look. It is explicitly designed to use a reference image for composition, pose, and lighting, but not for identity.
