Monochromatic Fine-Art Studio Portrait

A structured JSON prompt for Google Nano Banana 2 and Nano Banana Pro to generate a high-contrast monochromatic studio portrait of a young European woman. The prompt emphasizes natural facial proportions, realistic skin texture, minimal modern studio lighting (single focused key light), and a pure black, textureless background for a cinematic fine-art editorial aesthetic.
