2. **Write a prompt or upload a photo**: Describe the subject, setting, style and light, or upload images to edit.
3. **Choose Nano Banana 2 or Pro**: Nano Banana 2 costs 20 credits and is faster; Pro costs 45 and renders fine detail and text best.
4. **Refine and download**: Adjust the prompt, regenerate, and download in 1K, 2K or 4K.

## A prompt formula that works

Nano Banana understands full sentences better than keyword lists. A reliable structure is subject, action, setting, style and light, plus what must stay unchanged when you edit:

- Subject: “a golden retriever puppy”
- Action: “jumping over a puddle”
- Setting: “a cobbled street in Paris”
- Style: “photorealistic, 35 mm film”
- Light: “golden hour, soft shadows”
- When editing: “keep the face and the pose”

## How to use Nano Banana Pro

Use Nano Banana Pro when the image is final: product shots, posters with text, detailed illustrations and 4K prints. It follows long prompts more carefully and renders small text better, at a higher price per image. A good workflow is to explore with Nano Banana 2 and switch to Pro for the version you publish.


## Editing photos: what works best

Edits work best when you change one thing at a time and say explicitly what to keep. For bigger changes, such as a new background and a new outfit, run two edits in a row. Refer to uploads as image 1, image 2 and so on when you combine several pictures.
