Nano Banana 2 Prompt: The Complete Guide to Creative AI Commands

AI-powered image generation has come a long way — but few models blur the line between speed and creativity like Google’s Nano Banana 2. Built on the Gemini 3.1 Flash Image engine, it allows anyone to create cinematic visuals, stunning marketing layouts, or photorealistic product photos in just seconds.

But instant power means nothing without control. That’s where Nano Banana 2 prompts come in — learning how to write, structure, and refine them is the secret to unlocking pro-grade results.

Here’s your essential, readable, and creative guide to using Nano Banana 2 prompts effectively.

What Is Nano Banana 2?

Technically known as Gemini 3.1 Flash Image, Nano Banana 2 is Google’s third-generation AI image model launched in February 2026. It’s built for speed, semantic accuracy, and real‑time factual grounding.

Unlike earlier AI models, it doesn’t just “guess” what an image should look like — it understands composition, materials, light behavior, and even real‑world context.

Nano Banana 2 supports two major workflows:

Text‑to‑Image Generation – Create visuals from descriptive prompts.
Image Editing – Modify or enhance existing images with natural‑language instructions.

Think less software, more conversation. You tell it what you want, and it interprets like a creative partner.

Why Prompting Is Everything

The difference between an average result and a breathtaking one usually comes down to how you word the request. Nano Banana 2’s prompting system translates your text into visual reasoning — so clarity, intent, and structure matter more than ever.

Prompting is no longer just command‑based. It’s about speaking visually — as if you were briefing a photographer, art director, or designer. Done right, the model mirrors your creative vision.

The Core Anatomy of a Nano Banana 2 Prompt

Every strong Nano Banana 2 prompt contains six simple elements:

Subject – Who or what is in the frame
Action – What they’re doing or how they’re posed
Environment – Where it happens (studio, city street, forest, etc.)
Composition – Camera angle, distance, perspective
Lighting – Mood, time of day, or type of setup
Style – The artistic or cinematic tone

Example — Structured Prompt

A professional fashion portrait of a woman wearing a structured black blazer standing on a rooftop terrace at golden hour. 85mm lens, shallow depth of field, cinematic editorial photography style.

That single sentence delivers all six elements clearly — making the output realistic, consistent, and visually strong.

Five Proven Prompt Frameworks for Nano Banana 2

Here are practical frameworks creators use daily to craft better output faster.

1. Image Generation Prompts

Ideal for creating visuals from nothing.

Formula: Subject + Action + Location + Style

Example: A futuristic motorcycle racing through neon Tokyo streets at night, cinematic lighting, ultra‑wide 21:9 frame.

2. Image Editing Prompts

Used when editing an existing photo.

Example: Keep the person and lighting the same. Replace the background with a minimalist studio setting.

3. Multi‑Reference Prompts

Nano Banana 2 supports up to 14 reference images, meaning you can merge multiple assets.

Example: Use the first image for the person, the second for the outfit, and the third for the background cityscape. Keep the lighting consistent across all.

4. Typography & Text Rendering

Nano Banana 2 excels at text placement — one of its standout upgrades.

Example: Create a poster with the title “NANO BANANA 2 PROMPT GUIDE” in bold white sans-serif font centered on a charcoal background.

5. Creative Direction Prompts

Use these when treating your prompt like a mini photography or video brief.

Example: Dramatic portrait lit with Rembrandt lighting, captured on a 50mm lens, soft film grain, warm grading, cinematic tone.

Specify materials and light sources — Nano Banana 2 understands physical interaction between light and texture.
Combine camera language with atmosphere (“shot on telephoto lens,” “fog‑lit morning”).
