Vintage Flash Group Selfie Prompt for Nano Banana Pro

A structured JSON prompt for Nano Banana Pro to generate an indoor party selfie featuring three subjects (Sadie Sink, Sydney Sweeney, and the user) with a vintage flash aesthetic. The prompt specifies harsh direct flash lighting, tight composition, specific expressions (pout lips), and realism details like visible grain and skin texture, requiring three reference images for identity preservation.
