Nano Banana Pro Prompts

A user shares a prompt used on Nano Banana 2 to extract and upscale an image (likely a map for a Dungeons and Dragons campaign) from a book to fit a full screen.

This prompt is designed to generate images that mimic a high-end, soft 2D hand-drawn animation cel, treated like a cinematic film still. It specifies a muted pastel palette, strong directional lighting for shape separation, watercolor/gouache textures on paper, and subtle imperfections like line wobble, resulting in a quiet, moody, high-contrast aesthetic.
