Nano‑Banana – The Essentials

Introduction

Nano Banana is the name given to Google’s Gemini 2.5 Flash Image, the direct successor to Gemini 2.0. By entering natural-language instructions, you can perform precise edits while the system preserves speed, fidelity, and consistency. Nano Banana is now the recommended option for most editing tasks in Scenario. A separate variant, Nano Banana T2i, exists for generating images from scratch, but this guide focuses on editing capabilities.

Capabilities

With Nano Banana, you can transform visuals using simple text commands. Key features include:

• Object addition and removal – Insert new elements (e.g., a spaceship in the sky) or remove unwanted items (e.g., a signpost in the background) without selection tools.

• Object modification – Adjust the colour, texture, size, or style of existing objects. For example, change a red dress into a shimmering blue gown.

• Background manipulation – Modify the time of day, weather, or setting. For instance, turn a sunny beach into a moonlit night, or convert an indoor scene into a lush garden.

• Style transfer – Apply artistic styles such as oil painting, pencil sketch, or cartoon rendering.

• Image and element blending – Seamlessly merge multiple images or components into one composition. For example, place a character from one image into the background of another, or combine two reference photos into a unified design.

• Multi-step editing – Carry out several edits in sequence while maintaining coherence and character consistency. For example, repaint a room, then add furniture and décor in successive prompts without losing detail.

Accessing Nano Banana in Scenario

Nano Banana is fully integrated into Scenario’s Edit with Prompts tool. To start editing:

1. Open your image – Go to your gallery or workspace and select the image you want to edit. Click the three‑dot menu and choose Edit with Prompts.

   

2. Select the model – In the left‑hand panel, choose Nano Banana (Gemini 2.5 Flash Image). It is the default and recommended model for editing.

   

3. Upload additional images (optional) – Add extra reference images to guide the style or composition if needed.

Note: A separate Nano Banana – T2i model is also available in Generate Image or under Assets > Models. Use this variant when you want to create new images from scratch.

How to Use the Model

1. Write a clear prompt – Use natural language to describe the changes you want. Be specific about objects, colours, styles and actions. For example, instead of “make it nicer,” try “add string lights and change the walls to exposed brick.” You can also use Prompt Spark to generate suggestions and refine your wording.

2. Set the number of outputs – Choose how many edited images you want to generate.

3. Generate and iterate – Click Generate to create your edited image. Review the result and refine your prompt if needed. You can drag a generated image back into the reference slot to continue editing or combine multiple outputs.

Practical Examples

Here are the 28 practical use cases of Nano-banana's impact across creative industries, all created via Scenario's edit-with-prompts interface and fully reproducible:

1. Transforming a Scene

Let’s start with your daytime street photo and change it into a winter evening scene:

1. Open the image and select Edit with Prompts.

2. In the prompt box, type: Change the scene to a winter evening with falling snow, add holiday lights to the trees and warm glow from the windows.

3. Generate the edit. Nano Banana will transform the daytime street into a cozy winter night, adding snow, festive lights and warm lighting. If you want further adjustments—such as adding people wearing coats or removing the flowers—refine the prompt and generate again: Change the scene to a winter evening with falling snow. Add holiday lights to the trees and a warm glow from the windows. The streets should be covered in snow, people are wearing winter coats, and there are no flowers visible, since it’s winter.

2. Creating a Scene from a Sketch

1. Add the sketch to the reference image.

   

2. In the prompt box, write: “Generate a wide image (16:9 ratio, landscape). The image follows the positions of the characters on the sketch, plus the position of the tower. The three characters are gathered in a tense scene, in the style of Clash of Clans. The skeleton with glowing yellow eyes stands atop a grey stone tower with a brown wooden door, leaning forward as he waves a large axe menacingly. Below, the young girl knight with a golden helmet raises her sword, looking up as she prepares to strike at the tower. In the distance, across the grassy field, the young wizard boy in a red hat casts a glowing spell, focusing intently on the battle.”

3. Add Additional Images for each character.

   

4. Generate the image. Nano Banana will transform the sketch into a polished 3D-styled illustration, keeping the positions consistent but adding detail, depth, and atmosphere to match the Clash of Clans aesthetic.

   

3. Changing the Camera Perspective

Based on this dramatic scene of a dinosaur chasing a car on a forest road, and you want to change the perspective to make it look like the moment was captured from above by a drone:

1. Open the image and select Edit with Prompts.

2. In the prompt box, type:
   “Make the scene seen from a drone above”

3. Generate the edit. Nano Banana will transform the perspective, keeping the car, the dinosaur, and the road consistent, but showing everything from a high drone angle.

4. Generating the First and Last Frame of a Video Sequence

1. Add your image to the reference image.

   

2. In the prompt box, describe the closing moments of the sequence. For example:

   “Change the angle to the front camera showing a wider shot, change the singer's pose but keep her holding the microphone.”

3. Generate the edit. Nano Banana will produce ending frame of the sequence, keeping consistency in character, style, and environment, while adjusting the perspective and atmosphere to reflect the progression of the scene.

   

4. Now let's go to Create > Videos and select the Kling 2.1 Pro model. Upload the original image as the First Frame and the generated image as the Last Frame.

   

5. In the prompt box, write a general description of the scene, focusing on camera movements and the character’s actions. Click on Rewrite your Prompt. The tool will reformat your description into an optimized prompt for Kling 2.1 Pro, ensuring consistency between the first and last frame while enhancing cinematic flow and performance intensity. For example:

   A stylized 3D female singer with platinum blonde hair in a high ponytail, wearing a black leather jacket, layered necklaces, and ripped jeans, performs on stage under vibrant red and blue concert lights. She holds a microphone confidently, exuding charisma and attitude. The camera begins with a dramatic low-angle close-up, highlighting her fierce expression and glinting accessories. As the sequence progresses, the camera smoothly pulls back and rises into a medium full-body shot, showing her entire outfit, belt with ornate buckle, and the colorful lights illuminating the stage background. The atmosphere remains energetic and cinematic, with vivid concert lighting and a sense of live performance intensity.

   

6. Select the duration (5 or 10 seconds) and generate the video.

   Repeat to generate new frames and generate new sequences:

5. Character Pose and Action Modification
