Nano Banana 2 Prompt Guide: 15 Copy-Paste Prompts for Better AI Images

A practical Nano Banana 2 guide with prompt templates, quick-start workflow, and advanced controls for style, composition, and consistency.

Mar 1, 2026

Nano Banana 2 is the name many creators use for the latest Gemini native image generation stack, published with Gemini 3.1 updates on February 26, 2026. The biggest shift is not only image quality. It is the model's ability to generate and edit images in a conversational loop, so you can iterate with precise instructions instead of starting from zero each time.

If your goal is better images with fewer retries, this guide gives you a repeatable workflow and copy-paste prompts you can adapt in minutes.

What Nano Banana 2 Is (and What Changed)

At a practical level, Nano Banana 2 behaves like an image-first assistant that also understands text context well:

  • Strong prompt following for composition, lighting, and style.
  • Better text rendering inside images (posters, labels, UI mockups).
  • Native editing flow: upload or generate an image, then refine it with follow-up instructions.
  • Available through Google AI Studio and Gemini API as the preview image model.

For content teams, this means one model can cover ideation, first draft, and revision in the same thread.

Quick Start in 10 Minutes

Use this path when you need quality quickly:

  1. Start with one clear objective: product shot, social cover, ad visual, or explainer graphic.
  2. Pick one visual direction only (for example: "warm editorial photo" or "clean SaaS illustration").
  3. Use the prompt formula below and generate 3 variations.
  4. Keep the best output, then edit only one variable per turn (camera angle, color palette, text, or background).
  5. Export at the final aspect ratio needed by your channel.

Prompt Formula You Can Reuse

Use this structure for predictable outputs:

Create [asset type] in [style] for [audience/use case].
Subject: [main subject and key details].
Composition: [framing, camera angle, depth, focal length].
Lighting & color: [mood, temperature, palette].
Background: [environment and props].
Text in image (optional): "[exact text]".
Constraints: [what to avoid, brand rules, no extra elements].
Output: [aspect ratio, resolution priority, variation count].

When editing an existing image, append:

Keep identity and overall composition unchanged. Only modify: [single change].

Text in image:
"Write Less. Ship More."
"Try it free for 14 days"

Output: 1080x1350 feel, 4:5.
Create a cafe menu board graphic in chalk style.
Text in image:
"Morning Brew"
"Espresso 3.5"
"Cappuccino 4.5"
"Matcha Latte 5.0"
Constraints: keep typography consistent and readable from distance.
Output: vertical poster, 2:3.

Constraints: no spelling errors, high contrast text.
Output: 16:9.

D) Explainers and Diagram-Style Images

Create an educational infographic showing the lifecycle of a startup feature launch.
Include five steps with icons and arrows.
Style: flat vector illustration.
Color palette: navy, teal, orange accents.
Constraints: concise labels, even spacing, clean hierarchy.
Output: 3:2.
Generate a side-by-side diagram comparing "manual reporting" vs "automated reporting".
Style: corporate presentation slide graphic.

Output: 16:9.
Create a sticker sheet of 12 productivity-themed icons.
Style: playful flat stickers with white outline.
Constraints: transparent background, consistent stroke width.

E) Iterative Editing Prompts

Using the previous image, keep composition unchanged.
Only change color palette to warm sunset tones.
Do not modify subject pose or facial features.
Keep everything the same except replace the background with a modern office interior.
Match perspective and lighting direction to the original image.
Preserve the original design.
Only improve text clarity and kerning so all words are readable on mobile screens.

Advanced Tips for More Stable Results

  • Lock one variable at a time. If you change style, camera, and text together, debugging gets harder.
  • Add negative constraints early: "no extra fingers," "no watermark," "no extra logos."
  • For brand work, paste exact copy in quotes and explicitly require perfect spelling.
  • For consistency across a series, reuse one base prompt and change only the subject line.
  • For edits, start with "keep composition unchanged" to reduce unwanted rewrites.

Common Failure Modes (and Fixes)

  • Subject drift: the model changes identity too much. Fix: ask to preserve identity and limit edits to one attribute.
  • Text artifacts: words are close but not correct. Fix: shorten text, split into lines, and request exact spelling.
  • Over-stylized results: output looks synthetic. Fix: ask for natural skin texture, realistic materials, and softer lighting.
  • Busy composition: too many competing elements. Fix: specify one focal subject and 2-3 supporting props max.
