Nano Banana Prompt to Create Stunning AI Photos

A nano banana prompt is the line of text you paste into Google's Gemini image tool to edit a photo or build one from scratch. People nickname the model nano banana; the real name is Gemini 2.5 Flash Image. The grid at the top of this page is full of prompts you can copy right now. This part is about the words themselves: how a good prompt is built, and how to fix the ones that come out wrong.

What a nano banana prompt actually does

The model reads your photo and your instruction at once, so a prompt is half description, half rules. You tell it what to make and quietly tell it what to leave alone. That second part is where people slip: they describe a lovely scene but forget to say 'keep my face', so the output looks great and nothing like them. Plain English works best, no brackets or JSON-style formatting needed; a clear sentence beats a wall of fake code.

The shape of a nano banana prompt that works

Good prompts share the same skeleton. Write yours in this order:

1. The subject. Who or what is in the frame, in a few words.
2. The keep line. What from your photo must survive, usually the face and skin tone.
3. The look. Film grain, studio light, oil paint, soft editorial color.
4. The setting. Where it happens and how it is lit.
5. The framing. Close portrait, full body, three quarter angle.

Stitch those into one sentence: a portrait of me, keep my exact face, warm 35mm film look with soft grain, by a window in afternoon light, shot close.

Tip: decide the keep line before the look line. Nail the likeness first and you can throw any style at it; chase the style first and the face drifts.

Nano banana prompt styles to try right now

The looks shared most lean editorial and filmic. Pick a row, copy the wording into Gemini, swap in your own photo.

Keeping yourself recognizable

To get a usable set instead of one lucky image, lock your wording and reuse it. Keep the subject and keep line word for word and only change the scene or pose; the model holds likeness far better when most of the prompt stays put. When you need a different angle, add it plainly, like 'same person, same face, three quarter view, looking left.'

How to run a nano banana prompt

• Open Gemini and upload one clear, well lit photo.
• Paste the prompt from the grid above.
• Add 'keep the same face and skin tone' if a person needs to stay recognizable.
• Generate, then run it two more times and compare.

Results wobble run to run, so the second or third attempt is often the keeper. Save the wording that works so you can reuse it later.

When a nano banana prompt fights back

The face changed too much

Your style words are overpowering the likeness. Soften them and move 'keep my exact face' to the front so the model reads it first.

The skin looks like plastic

Add 'natural skin texture, visible pores' and start from a sharper input photo. Over-smoothing usually comes from a soft input, not the prompt.

It refused to generate

Nano banana moderates hard on photos of real people, celebrities, and children, and tends to decline upfront. If you hit a wall, change the subject or use a photo you clearly have the right to use.

The prompts here are free to copy, and Gemini's free tier covers everyday edits; heavy batch use runs through the paid API at a few cents an image. Pick any prompt, drop in a sharp photo, and run it three times before you judge it.
