How to Create Effective Image Prompts with Google Nano Banana — Complete Guide with Formula, Examples, and Pro Tips

TamilTech AI summary

Google’s Nano Banana is a fast, free AI image model inside Gemini and Google AI Studio, and the pictures you get depend almost entirely on how well you write your prompts. The guide’s core tip is a simple 6-element formula—Subject, Composition, Action, Setting, Style, and Technical details—that you combine in roughly that order so you stay in control of the result. It walks through clear examples (product shots, portraits, landscapes), plus advanced moves like asking for variations, using reference images, writing creative-director briefs, and picking the right aspect ratio for social or print. You’ll also learn the usual mistakes to skip—being vague, mixing conflicting moods, or forgetting lighting—and get ready-made templates aimed at Indian creators for food, tech, travel, and more. Master the formula, keep prompts specific rather than long, and you’ll consistently get the exact images you want.
