Google Gemini Nano Banana AI: Steps to convert your photo into figurines, best prompts you should know and more

Gemini’s Nano Banana model makes it simple to convert a normal photo into a polished, collectible‑style 3D figurine image—complete with acrylic base, studio lighting, and toy‑box packaging context. The workflow is fast, free to try in the Gemini interface, and requires only a good portrait and a precise prompt.

Step-by-step guide: Photo to figurine
Prepare a clear portrait or full‑body image with good lighting and a neutral background. This helps the model preserve facial features and clothing details.
Open Gemini, select the image generation/editing experience, and upload the photo. For best fidelity, keep the subject centered and unobstructed.
Paste a detailed composition prompt (see below), then generate. Review the result and iterate by editing one element per pass—pose, base style, lighting, or packaging—until satisfied.
Export in the highest available resolution. If face likeness drifts, re‑upload the same photo and reduce creative changes in the next prompt.

Best prompts you should know

Realistic desk showcase
“Create a 1/7 scale commercialized figurine of the person in the photo, in a realistic style, placed on a sleek computer desk. Show the figurine on a round transparent acrylic base with no text. On the monitor, display the 3D sculpting process (gray clay model). Place a BANDAI‑inspired packaging box with flat 2D artwork of the character next to the monitor. Use warm directional desk‑lamp lighting with soft reflections on the acrylic.”
