Sepia-Toned Film Photography Aesthetic Prompt

A JSON prompt for Nano Banana Pro focusing on generating an image with a specific film photography aesthetic. It details a warm, sepia-toned look with noticeable film grain, natural vignetting, and diffused daylight. The composition features a subject seated slightly off-center, framed by a large window, creating an asymmetrical balance and a documentary style. Via YouMind OpenLab prompt library (MIT).
