Nano Banana Image Edit Guide
2025-09-29
Introduction
This guide builds on our previous Nano Banana Image Generation Guide, which covered the basics of creating images with Google's powerful AI model. Now, we'll focus specifically on editing existing images.
Nano Banana, Google's image generation model within the Gemini API, excels at precise image editing as well as creating stunning images from text prompts. Users can modify existing images by adding objects, changing backgrounds, or transforming styles using simple, natural language instructions.
The tool understands contextual editing requests and maintains visual coherence throughout the editing process. This makes it invaluable for designers, content creators, and anyone who needs quick image modifications without learning complex editing software.
Let's unlock Nano Banana's full potential for seamless image editing with this guide. Below is the image we generated in our previous guide—we'll use this as our starting point.
Guides for Editing
1. Adding and removing elements
Nano Banana excels at modifying existing images while maintaining visual consistency. To edit an image, simply provide the image and describe your desired changes. The model will automatically match the original image's style, lighting, and perspective.
Example Prompt:
Using the provided image of an underwater scene featuring a vibrant octopus and a scuba diver, please remove the diver from the scene. Ensure the change is seamless — the surrounding water, light rays, and coral should naturally fill the space where the diver was, maintaining the depth, lighting, and marine ambiance without any visible artifacts or unnatural gaps.
2. Changing styles and backgrounds
Nano Banana also allows you to edit just a specific part of an image while keeping the rest unchanged. This is particularly useful when you want to make targeted modifications without affecting the entire composition.
Example Prompt:
Using the provided image, change only the octopus to a blue-ringed octopus. Keep everything else in the image exactly the same, preserving the original style, lighting, and composition — including the surrounding coral, water clarity, and ambient glow — while accurately rendering the blue-ringed octopus’s distinctive iridescent blue rings and yellowish-brown base coloration on its mantle and arms.
3. Style transfer
Nano Banana can transform your images into various artistic styles, mimicking the techniques and visual aesthetics of famous artists or art movements.
Example Prompt:
Transform the provided photograph of an underwater scene with an octopus and coral into the artistic style of traditional Chinese ink wash painting. Preserve the original composition but render it with soft, flowing brushstrokes, subtle gradations of gray and muted earth tones, and minimal color saturation — avoiding bright or vivid hues to maintain a serene, monochromatic atmosphere characteristic of classical ink wash aesthetics.
4. Advanced composition: Combining multiple images
Nano Banana can combine multiple images as context to create entirely new composite scenes. This capability is particularly valuable for designers creating product mockups, marketing materials, or creative collages.
Example Prompt:
Create a new image by combining the elements from the provided images. Take the octopus and place it on the boat. The final image should be a octopus is attacking the boat in the pure blue ocean.
5. High-fidelity detail preservation
With Nano Banana, you can preserve critical details (like a face or logo) during an edit by describing them comprehensively in your prompt. Be specific about what elements should remain untouched, as this guides the model to maintain the integrity of important features while implementing your requested changes.
Example Prompt:
Using the provided images, place the octopus onto the white T-shirt. Ensure that the features of T-shirt and the man wearing the T-shirt remain completely unchanged. The added element should look like it's naturally printed on the T-shirt.
