How to Create an Effective Prompt for Nano Banana Pro

The author details how to effectively prompt Google’s Nano Banana Pro, a visual reasoning model, emphasizing that success relies on structured design documents rather than vague requests. The method prioritizes four key steps: defining the Work Surface (e.g., dashboard or comic), specifying the precise Layout, listing all required Components, and enforcing strict Constraints to maintain consistency. This approach leverages the model's distinct engines (like Layout, Typography, and Style) to create complex, structurally coherent visual artifacts, proven through an ambitious comic book adaptation project.
