Nano Banana 2 Prompts: How to Write Better Prompts Fast

Why Nano Banana 2 Prompts Matter

Nano Banana 2 can do a lot with simple language. But the quality still depends on how clear your prompt is.

A good prompt helps the model understand:

• What the subject is
• What style you want
• What the camera should feel like
• What text belongs in the image
• What must stay fixed

That is why many users search for Nano Banana 2 prompts instead of just “AI prompts.” They want prompts that work for real jobs, not vague demos.

The Fast Prompt Formula

Use this simple structure:

Subject + action + style + lighting + composition + text + keep/avoid

You do not need every part every time. But this order makes prompts easier to write and easier to improve.

A Simple Prompt Template

[subject], [action or scene], [visual style], [lighting], [camera angle or framing],
[important text in image], [details to keep], [things to avoid]

Here is a plain example:

A premium coffee bag on a clean retail shelf, soft natural light, front-facing product shot,
minimal editorial style, headline text says "Fresh Roast", keep the logo shape unchanged,
avoid clutter, warped text, and extra products.

1. Start With the Main Subject

Say what the image is about first.

Good:

• A white sneaker on a studio floor
• A skincare bottle on a marble counter
• A family-friendly pizza menu poster

Weak:

• Make something cool
• Create a nice image
• Improve this

The clearer the subject, the better the first draft.

2. Add the Job, Not Just the Look

Many prompts fail because they describe the style, but not the task.

Tell Nano Banana 2 what the image is for:

• Product ad
• Poster
• Menu
• Social graphic
• Storyboard frame
• Ecommerce image
• Explainer diagram

When the task is clear, the layout and details are easier to control.

3. Be Specific About Text in the Image

If the image needs text, write the exact text.

Bad:

Add some nice text

Better:

Add headline text: "Weekend Sale"
Add subhead text: "Up to 40% off"
Use clean, readable sans-serif type

If text clarity matters, keep it short on the first pass. Then refine.

4. Use “Keep” Instructions for Better Control

Nano Banana 2 gets better when you tell it what should not drift.

Useful keep instructions:

• Keep the face identity unchanged
• Keep the product shape unchanged
• Keep the package colors the same
• Keep the layout centered
• Keep the logo position fixed

This is especially useful for edits and multi-image references.

5. Add One Style Direction, Not Five

Too many style words often create muddy results.

Better:

• Clean editorial style
• Warm cinematic lighting
• Soft watercolor illustration
• Minimal ecommerce photography

Worse:

• Cinematic, editorial, anime, retro, brutalist, dreamy, glossy, moody, realistic

Pick one main style. Add one supporting note if needed.

6. Tell the Model What to Avoid

Negative instructions save time.

Useful examples:

• Avoid extra fingers
• Avoid cluttered background
• Avoid warped text
• Avoid duplicate products
• Avoid heavy blur

You do not need a huge negative list. Two or three focused limits are enough.

Prompt Examples for Common Searches

Nano Banana 2 prompt for a poster

Create a modern music festival poster, bold headline text says "Summer Lights",
small date line says "July 18", high contrast lighting, energetic crowd scene,
clean layout, readable text, avoid broken letters and messy spacing.

Nano Banana 2 prompt for a product image

A premium glass serum bottle on a beige stone pedestal, soft side lighting,
clean beauty campaign style, front-facing composition, keep the bottle label sharp,
avoid extra props and avoid warped packaging text.

Nano Banana 2 prompt for an image edit

Replace the background with a bright modern kitchen, keep the person and shirt unchanged,
soft morning light, realistic shadows, keep skin tones natural, avoid changing face identity.

Nano Banana 2 prompt for multilingual text

Create a clean product banner with readable English and Chinese text,
headline says "Smart Cooling Fan", subhead says "Quiet. Compact. Powerful.",
minimal white layout, product centered, avoid broken text and uneven alignment.

When to Add Reference Images

Use reference images when the prompt alone is not enough.

That usually means:

• A face must stay recognizable
• A product shape must match the original
• A brand layout must stay close
• A sketch should guide the final image

If that sounds like your task, move to the Nano Banana 2 image-to-image guide.

Common Prompt Mistakes

Mistake 1. The prompt is too short

Short prompts can work, but they often leave too much open.

Mistake 2. The prompt mixes too many styles

One main style is stronger than a long list of style words.

Mistake 3. The prompt forgets the text

If text matters, write the exact words.

Mistake 4. The prompt never says what to keep

This is a common problem in edits. If identity matters, say so.

A Better Workflow for Nano Banana 2 Prompts

1. Start with one clear prompt.
2. Fix the subject and job first.
3. Add style and lighting next.
4. Add text and keep instructions.
5. Generate a few versions.
6. Refine only one variable at a time.

This is faster than rewriting the whole prompt each round.

FAQ

How long should a Nano Banana 2 prompt be?

Long enough to define the subject, job, style, text, and what should stay fixed. Usually a clear medium-length prompt works better than a very short one.

Should I use negative prompts?

Yes, but keep them short. Focus on the two or three things most likely to break the image.

Do I need a different prompt for editing?

Usually yes. Edit prompts should say what to change and what to keep.

Final Take

The best Nano Banana 2 prompts are clear, specific, and calm. They say what the image is, what it is for, what text belongs in it, and what must not change.

That is how you get better output faster.
