A detailed prompt (v.066) for Nano Banana to generate a cinematic, high-contrast image. It specifies a medium eye-level shot of a subject in a black long coat making a stopping gesture, with metallic projectiles suspended in the foreground and a dark, ornate background, rendered with a monochromatic green wash and 35mm film grain.
"Image from subject, medium eye-level shot. Subject standing, looking directly forward, right arm extended with flat palm in a stopping gesture. Suspended metallic projectiles fill the foreground in mid-air. Wearing a high-collared black long coat and dark oval sunglasses. Background features dark, ornate walls with a classical mural and wood paneling. Heavy monochromatic green color wash. High-contrast directional lighting with deep shadows and specular highlights on the floating metal. Shallow depth of field, cinematic 35mm film grain. "
