Complete Guide to Nano Banana Pro

Nano-Banana Pro is not just another "fun image model". It's designed for producing professional assets: presentations, infographics, campaign creatives, brands, storyboards and more.

The model excels in 5 core capabilities:

Readable text inside images, character consistency, visual synthesis of complex information, connection to Google Search for working with current data, and very high resolution images up to 4K.

This post summarizes the main capabilities of Nano-Banana Pro, and more importantly: how to write prompts for it smartly, as if you're briefing an experienced art director.

0. The Golden Rules of Prompting

Nano-Banana Pro is defined as a "thinking" model. It doesn't just look for individual words, it understands context, intention, physics, composition and story.

To get "studio-level" results, stop thinking in "tag soup" terms like:

"dog, park, 4k, realistic"

And start acting like a creative/art director explaining to a person.

1. Edit, Don't Discard

If you got an image that's 70–80% what you wanted, don't start from scratch.

Instead of: "Try again"

Say: "That's great, but change the lighting to sunset and make the text neon blue"

2. Use Natural Language and Full Sentences

Like a brief to a real designer.

❌ Wrong: "Cool car, neon, city, night, 8k"

✅ Right: "A wide cinematic shot of a futuristic sports car speeding through a rainy Tokyo street at night. Neon signs reflect on the wet asphalt and the metallic body of the car."

3. Be Specific

"Girl" is one vision. "An elegant elderly woman in a Chanel-style suit" is a completely different vision.

Pay attention to details:

• Who is the subject? Age, style, vibe
• Where does it happen? Street, office, studio, nature
• Lighting: strong sun, soft light, urban night
• Textures: shiny metal, rough natural wood, soft velvet, crinkled paper

4. Give Context: Why and For Whom

When you explain why the image is intended, the model understands which style is appropriate.

"Create an image of a sandwich for a Brazilian high-end gourmet cookbook." (The model will infer professional plating, shallow depth of field, and perfect lighting)

1. Text in Images, Infographics & Visual Synthesis

One of Nano-Banana Pro's strengths is readable, clean text inside images, and the ability to turn dense material (reports, presentations, PDFs) into organized infographics.

Key Use Cases

• Infographics for financial reports
• Technical diagrams
• Knowledge summaries for learning or training
• Campaign creatives with clear text

Working Principles

• Compression: Ask the model to "compress" a large document into one visual.
• Style: Define upfront: "polished editorial", "technical diagram", "hand-drawn whiteboard"
• Text in quotes: Any text that must be exact, put in quotes.

Example Prompts

P&L Infographic:

"Generate a clean, modern infographic summarizing the key financial highlights from this earnings report. Include charts for 'Revenue Growth' and 'Net Income', and highlight the CEO's key quote in a stylized pull-quote box"

Retro Infographic:

"Make a retro, 1950s-style infographic about the history of the American diner. Include distinct sections for 'The Food,' 'The Jukebox,' and 'The Decor.' Ensure all text is legible and stylized to match the period"

Whiteboard Summary:

"Summarize the concept of 'Transformer Neural Network Architecture' as a hand-drawn whiteboard diagram suitable for a university lecture. Use different colored markers for the Encoder and Decoder blocks, and include legible labels for 'Self-Attention' and 'Feed Forward'"

2. Character Consistency & Viral Thumbnails

Nano-Banana Pro can "lock identity" across up to 14 reference images (6 at high fidelity).

This means you can:

• Put the same person in dozens of different situations
• Without face distortion
• Without mixing different people

Tips for Working with Characters

• Explicitly state: "Keep the person's facial features exactly the same as Image 1."
• Separate who the person is from what they're doing (pose, expression, camera angle)
• Describe the change in emotion or pose while maintaining the identity

Viral Thumbnail Example:

"Design a viral video thumbnail using the person from Image 1. Face Consistency: Keep the person's facial features exactly the same as Image 1, but change their expression to look excited and surprised. Action: Pose the person on the left side, pointing their finger towards the right side of the frame. Subject: On the right side, place a high-quality image of a delicious avocado toast. Graphics: Add a bold yellow arrow connecting the person's finger to the toast. Text: Overlay massive, pop-style text in the middle: 'Done in 3 mins!'. Use a thick white outline and drop shadow. Background: A blurred, bright kitchen background. High saturation and contrast."

3. Grounding with Google Search

Nano-Banana Pro is connected to Google Search, so it can generate visualizations based on:

• Up-to-date information
• Trends
• Real data

The model "thinks" about the search results, and only then generates the image.

Example:

"Generate an infographic of the best times to visit the U.S. National Parks in 2025 based on current travel trends"

4. Advanced Editing, Restoration & Colorization

Nano-Banana Pro can perform complex edits without manual masks.

It can:

• Remove and add objects (In-painting)
• Restore old photos
• Colorize manga / black & white
• "Translate" an ad to another country/culture (both text and visual)

Working Principles

• Explain in natural language what you want to happen in the image
• No need to explain exactly where to paint a mask
• You can request physical actions, like "fill the glass with red wine"

5. 2D to 3D Translation

One of the more interesting capabilities for designers and architects is converting:

• 2D floor plans into 3D visuals
• Or converting a 2D sketch/drawing into realistic rendering

Example:

"Based on the uploaded 2D floor plan, generate a professional interior design presentation board in a single image. Layout: A collage with one large main image at the top (wide-angle perspective of the living area), and three smaller images below (Master Bedroom, Home Office, and a 3D top-down floor plan). Style: Apply a Modern Minimalist style with warm oak wood flooring and off-white walls across ALL images. Quality: Photorealistic rendering, soft natural lighting"

6. High Resolution & Textures

Nano-Banana Pro supports very high resolution images, up to 4K.

For texture work:

"Generate a seamlessly tiling texture of rough, weathered concrete with visible aggregate and water stains. The texture should be suitable for use as a 4K PBR material in a game engine, with consistent lighting across the tile."

7. Visual Reasoning & Logic

The model can solve visual puzzles, read charts, and generate solutions.

Example:

"Solve this chess puzzle and generate an image showing the correct next move with arrows indicating the piece movement"

8. Storyboard & Concept Art in One-Shot

Nano-Banana Pro can generate complete storyboards in a single prompt.

Example:

"Create a 6-panel storyboard for a 30-second TV commercial for a luxury perfume. The narrative arc should go from 'mysterious stranger in Paris' to 'intimate close-up of the bottle'. Include camera direction notes below each panel. Style: cinematic, high contrast, desaturated with gold accents."

9. Structure & Layout Control

You can specify exact layout requirements:

"Create a 3-column magazine spread layout. Left column: portrait photo of subject. Middle column: pull quote in large type. Right column: body text in two sub-columns. Include a full-bleed header image at the top spanning all columns."

10. What to Do With This Now

Start with one use case that costs you the most time today:

1. If you make a lot of presentations → start with infographic generation
2. If you create social content → start with character consistency + thumbnails
3. If you do campaign work → start with ad localization + text-in-image
4. If you're in architecture/design → start with 2D to 3D conversion

The key is not to explore every feature at once. Pick one, master it, then expand.
