Cinematic Film Still Nano Banana Prompts

$An old street in pouring rain, with dim yellow streetlights, distorted neon signs reflected on the wet ground, and a person holding a transparent umbrella standing at the center of the frame, face not visible, shallow depth of field, cinematic composition, 8K, grainy texture, with a slightly blue-green cool tone. An ancient cathedral completely submerged underwater. Sunlight penetrates the water surface, with volumetric rays filled with floating particles. Stained glass windows cast colorful patterns onto the stone floor, tens of thousands of tiny bubbles rise up, and a diver wears a sleek suit. Turn the design draft into a realistic product photo.
