Nano Banana Prompts: A Complete Guide to Better Results
Nano Banana has become a popular choice for photo-realistic AI image editing because it handles reference images and identity preservation well. This guide explains how to structure prompts specifically for Nano Banana to get consistent, high-quality results.
Why do some Nano Banana results look inconsistent?
Nano Banana performs best when prompts clearly separate what should stay the same from what should change. Inconsistent results usually happen when instructions are vague, contradictory, or when too many edits are requested in a single generation.
Common causes
- Unclear reference image quality
- Requesting too many simultaneous edits
- Not stating which elements must remain unchanged
- Overloading the prompt with unrelated style keywords
- Ambiguous instructions about pose or composition
- Skipping a review step between edits
Practical solutions
Lead with identity preservation
Start the prompt by telling Nano Banana to keep the uploaded person's face, proportions and identity unchanged.
Make one change per generation
Edit clothing, background or pose separately rather than combining several major changes in one prompt.
Be explicit about what stays fixed
Clearly state which elements, such as facial identity or an existing outfit, must not be altered.
Use natural, structured language
Write prompts as clear instructions rather than long strings of disconnected keywords.
Nano Banana editing prompt example
Using the uploaded photo, keep the person's face, identity and body proportions exactly the same. Change only the outfit to a fitted navy blazer over a white shirt, and replace the background with a softly lit modern office. Maintain realistic lighting and natural skin texture throughout.Step-by-step fix
- 1Upload a clear, high-resolution reference photo.
- 2State the identity-preservation instruction first.
- 3Describe only the single change you want made.
- 4Review the output before requesting the next edit.
- 5Reuse the same reference image across a series for consistency.
Tips for better results
- Avoid stacking multiple unrelated edits in one prompt.
- Keep a saved template of your identity-preservation instruction.
- Use simple, well-lit reference photos for the most reliable results.
- Break complex scenes into smaller, sequential edits.

Frequently asked questions
What makes a good Nano Banana prompt?
A good prompt clearly preserves identity, requests one change at a time and avoids conflicting or overloaded instructions.
Can Nano Banana edit a photo without changing the face?
Yes, when the prompt explicitly instructs it to preserve the uploaded person's facial identity while changing only specified elements.
How is Nano Banana different from other AI image tools?
Nano Banana is generally used for photo-realistic editing and identity-preserving transformations rather than purely artistic image generation.
