Suggestions on how to write commands to create images in Nano Banana

Create images

When creating images, the command structure depends entirely on whether you use reference images or rely solely on text.

When you start with a blank page, you are the director. A simple keyword list will not be enough for an AI to understand; You need to describe the scene clearly and in detail like telling a story.

Recipe: [Chủ thể] + [Hành động] + [Địa điểm/bối cảnh] + [Bố cục] + [Phong cách]

Suggested example: [Chủ thể] A fashion model wears a tailored brown dress, elegant boots, and holds a box bag. [Hành động] Pose with a confident, flexible posture, slightly turned. [Địa điểm/bối cảnh] Seamless dark cherry red studio backdrop. [Bố cục] Central panorama, center frame. [Phong cách] Fashion magazine editorial style, shot with medium format analog film, obvious grain, high saturation, cinematic lighting effects.

Create shapes with references

Gemini allows you to combine multiple reference images to guide the final result. This is great for maintaining character consistency or integrating a specific product into a new environment.

Recipe: [Hình ảnh tham chiếu] + [Hướng dẫn về mối quan hệ] + [Kịch bản mới]

For example: Use the attached napkin sketch as structure and the attached fabric swatch as texture [Tham chiếu]convert it into a high-resolution 3D armchair image [Mối quan hệ]. Place it in a minimalist, sun-filled living room [Kịch bản mới].

Note: Nano Banana also generates source images for the examples below.

Photo editing

Editing requires a different mindset than creating images. From the original image, you ask Nano Banana to focus on what’s changing and what’s staying the same.

Edit by dialogue, no new references

When you create an image and want to edit it using dialogue:

Semantic overlay (fill in): You can define a “mask” through text to edit a specific part of the photo while leaving the rest intact.

Tips for making requests: Be clear about what needs to stay the same.

Request example: “Remove man from photo”

Switch layouts and styles with new references

Include a new photo in the request to change an existing photo:

Add elements: Upload the original photo and the object photo, and ask Nano Banana to combine them.

Style conversion: Upload a photo and ask the model to recreate its exact content in a different artistic style, such as turning a modern street photo into a Van Gogh-style painting.

Create images with the latest information from web searches

The Gemini Image model can proactively search the web to generate images based on real-time information.

Instead of depicting a fictional scene, you instruct Nano Banana to retrieve actual data and then specify how to visualize that data.

Recipe: [Nguồn/Yêu cầu tìm kiếm] + [Nhiệm vụ phân tích] + [Chuyển đổi trực quan]

For example: [Tìm kiếm thời tiết và ngày hiện tại ở Hà Nội] + [Sử dụng dữ liệu này để phân tích và chỉnh sửa cảnh (ví dụ: nếu trời mưa, hãy làm cho nó trông xám xịt và có mưa)] + [Trực quan hóa điều này dưới dạng một mô hình thành phố thu nhỏ trên màn hình điện thoại.
