The AI Nano Banana Technique
Why use Nano Banana instead of a plain prompt?
When generating multiple images of the same character, AI models tend to change facial features and distinctive details between outputs. The Nano Banana technique uses a reference photo upload alongside your prompt — instructing the AI to preserve:
- Exact face from the reference image
- Tattoos on the arm (in this set: the "21" tattoo)
- Overall style and vibe of the subject
How to use it in Gemini:
- Open Gemini → New conversation
- Upload the reference photo of your model
- Paste the prompt and include
