About This Prompt

A structured JSON prompt for Gemini Nano Banana Pro to generate a candid, knees-up portrait of a young woman on a wet city street during gentle snowfall. The prompt details her layered winter outfit (burgundy oversized coat, tailored trousers), the environment (historic skyscraper, wet asphalt), and the photography style (intimate iPhone snapshot, cool desaturated tones, film grain), with strict negative prompts for facial preservation.
