How to Prompt Nano Banana Pro: A Guide to Creating High-Quality Images with Google’s AI
Why Nano Banana Pro Matters
Nano Banana Pro is Google DeepMind’s most advanced image generation model, built on the powerful Gemini 3 Pro architecture. It delivers high-resolution outputs (up to 4K), understands complex prompts with layered context, and performs exceptionally well when generating realistic lighting, textures, and dynamic scenes. It also supports image referencing — letting you upload photos or designs to guide the visual consistency.
In short, it’s not just a toy — it’s a tool for designers, marketers, illustrators, and creatives who want to build professional-grade images fast. But to unlock its full potential, you need to learn how to prompt it properly.
Prompting Basics: Clarity Beats Cleverness
The secret to powerful results isn’t trickery — it’s clarity. Nano Banana Pro doesn’t need keyword spam or obscure syntax. It needs you to be specific and structured.
Here are the key rules to follow:
- Be descriptive, not vague: Instead of “a cat,” write something like “a ginger British shorthair cat sitting on a marble countertop under soft morning light.
- Layer your descriptions: Include details about the subject, setting, atmosphere, materials, lighting, style, and mood.
- State your format: Tell the model if you want a photo, digital painting, cinematic frame, 3D render, infographic, comic panel, etc.
- Use reference images: Nano Banana Pro supports multiple uploads — useful for matching styles, poses, faces, characters, or branding.
This is how professionals prompt: not by hacking the system, but by being precise about what they want.
Crafting Prompts by Use Case
📸 Realistic Photography
Want a product photo, fashion portrait, or cinematic still? Then your prompt should include lens type, lighting style, subject age, composition, and color grading.
Example:
Professional studio portrait of a 35-year-old woman in natural light, soft cinematic lighting, shallow depth of field, 85mm lens look, natural skin tones, soft shadows, clean background, editorial style.
Another example:
A 3/4 view of a red sports car parked in a luxury driveway at golden hour, realistic reflections, soft shadows, DSLR-style image, bokeh background.
These prompt structures help the model replicate not just the subject but the feel of a professionally shot image.
🎨 Illustration, Comic Art, and 3D Concepts
If you want stylized work — like a retro comic, anime-style character, or matte painting — the style must be part of the prompt.
Example:
Comic-style wide cinematic illustration, bold black outlines, flat vibrant colors, halftone dot shading, a heroic female astronaut on Mars with a pink sky, dramatic lighting, wide aspect ratio.
More styles to try:
- Fantasy concept art, a medieval knight riding a dragon above stormy mountains, painted in the style of Frank Frazetta, high detail, dramatic lighting.
- Cyberpunk anime character in a rain-soaked Tokyo alley, glowing neon lights, futuristic fashion, overhead perspective, digital painting.
Tip: Reference known artistic styles (e.g., Art Nouveau, Impressionism, Pixar, Studio Ghibli) to guide the tone.
🔄 Editing Existing Images
Nano Banana Pro can also transform existing images by changing backgrounds, lighting, or adding/removing objects.
Examples:
Replace the background with a rainy city street at night, reflect soft blue and orange lights on the subject, keep original pose and composition, cinematic tone.
Add a glowing book in the subject’s hands, soft magical light cast on their face, night-time indoor setting.
Best practices:
- Use clear “before/after” language.
- Indicate what must stay unchanged.
- Specify the mood or lighting effect you want added.
Common Mistakes to Avoid
- Too generic: A prompt like “a girl standing” tells the model almost nothing. Who is she? Where is she? What’s the style?
- Keyword stuffing: Don’t use outdated tricks like “masterpiece, ultra-detailed, trending on ArtStation.” They’re mostly ignored.
- Ignoring context: Don’t forget to describe how elements relate (e.g. “holding a glowing orb” vs. “glowing orb floating behind her”).
- Unclear intent for text/logos: If you want branded material, say exactly what the logo or label should look like, and where.
Prompt Templates You Can Use Right Now
Try adapting these for your needs:
- “Cinematic 4K photo of a mountain climber reaching the summit at sunrise, orange glow on snowy peaks, lens flare, dramatic sky.”
- “Retro-futuristic 3D render of a diner on Mars, neon signs, dusty surface, stars in the background, warm ambient light.”
- “Isometric vector-style infographic showing renewable energy sources, solar, wind, hydro, with icons and labels.”
- “Realistic photo of a smartwatch product on a floating glass platform, minimalistic white background, soft shadows.”
These prompts are short but rich in visual instruction — and that’s the key to strong output.
Going Further: Advanced Prompting Tips
- Use cinematic language: Words like “soft light,” “overhead shot,” “close-up,” “medium angle,” “shallow depth of field” guide the AI like a film director.
- Test with reference images: Upload an image of your brand, product, or character to maintain continuity.
- Iterate: If your first image isn’t right, adjust one or two variables (e.g., lighting, background, subject age) and regenerate.
- Define aspect ratios: Use “cinematic,” “vertical portrait,” “square crop” if you need a specific format.
- Stay natural: Write prompts like you’re briefing a professional illustrator or photographer.
Final Thoughts
Nano Banana Pro is one of the most powerful visual AI tools available — but it’s only as good as your prompts. Whether you’re an art director, a solo founder, or a content creator, learning to prompt well is the fastest way to unlock its full creative range.
Focus on clarity, visual language, and style specificity. Add references when needed. Think like a photographer, art director, or storyteller. The better your brief, the better the image.
