Nano Banana 2 Image to Image Guide for Edits, References, and 4K

What “Nano Banana 2 Image to Image” Usually Means

When people search for Nano Banana 2 image to image, they usually want one of these things:

• Turn a photo into a new style
• Keep a subject, but change the scene
• Use one or more references to guide a new image
• Keep a product or face consistent across several results
• Improve the image and then upscale it for delivery

That is different from plain text-to-image. Here, the starting image matters.

Image to Image vs Image Editor

The two workflows are related, but not the same.

Use image-to-image when:

• You want a new image based on a reference
• You want stronger restyling
• You want a sketch, photo, or layout to guide a new output
• You want to mix several references into one result

Use the image editor when:

• You want smaller, precise changes
• You want to keep most of the original photo
• You need targeted fixes like relighting, text repair, or background cleanup

You can start in Nano Banana 2 image-to-image and move to the image editor when you want finer control.

The Best 4-Step Workflow

1. Upload the best reference image you have.
2. Write a prompt that says what should change and what should stay fixed.
3. Add more references if identity or layout matters.
4. Pick the best version, then upscale it if you need sharper output.

This is simple, but it covers most real use cases.

How to Write a Better Image-to-Image Prompt

A strong image-to-image prompt has two parts:

• What to change
• What to keep

Use this template:

Change [thing to change], keep [thing to keep], use [style or mood],
keep [identity, product shape, layout, or text], avoid [main failure]

Example:

Change the plain studio background into a warm cafe interior, keep the coffee bag shape and logo unchanged,
soft afternoon light, clean lifestyle ad style, keep the product centered, avoid extra products and warped text.

When to Use More Than One Reference Image

One reference image is fine for simple jobs.

Use multiple references when:

• One image has the face you want
• One image has the product you want
• One image has the background or mood you want
• One sketch defines the layout you want

This is how you get better consistency without overloading the prompt.

Good Use Cases for Nano Banana 2 Image to Image

Product marketing

Upload a real product shot. Change the set, the color world, or the placement while keeping the product shape stable.

Character consistency

Use face references and keep the same identity across storyboards, ads, or social content.

Sketch to polished image

Start from a wireframe, drawing, or layout. Turn it into a cleaner final scene.

Poster updates

Reuse the same key visual, but change the season, color, language, or headline.

How to Keep Faces and Products Stable

If consistency matters, follow these rules:

• Use clear reference images
• Say exactly what must stay unchanged
• Change only one or two big things at a time
• Keep the style direction focused
• Do not overload the prompt with too many ideas

This is often more effective than writing a much longer prompt.

How to Handle Text in an Image-to-Image Workflow

If the final image includes text, treat the text as a key part of the prompt.

Write:

• The exact words
• Where the text should go
• What style the text should have
• What should remain readable

Short text is easier on the first pass. After that, refine the wording and spacing.

How to Get 4K-Ready Results

Image-to-image is usually the creative step. Upscaling is the delivery step.

Use this order:

1. Get the content right
2. Fix the layout and text
3. Confirm the subject looks right
4. Upscale in the Nano Banana 2 image upscaler

That is the cleanest path to sharper output.

Common Mistakes

Mistake 1. The reference image is weak

Blurry or cluttered references create weaker results.

Mistake 2. The prompt only says what to change

If you do not say what to keep, the image can drift.

Mistake 3. Too many goals in one pass

Do not change the background, style, pose, text, and composition all at once unless you must.

Mistake 4. Upscaling too early

Wait until the content is right. Otherwise you spend time sharpening the wrong version.
