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

Google Gemini

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.”

Minimal studio product shot
“Render a 1/6 scale collectible figure of the subject on a clear circular acrylic base, on a seamless white backdrop. Add softbox lighting, subtle shadows, and a glossy reflection under the base. No text, logos, or watermarks in the scene.”

Cinematic shelf display
“Create a stylized 3D figurine of the person, 1/7 scale, posed heroically on a transparent base, displayed on a wooden shelf with soft rim light and bokeh. Include a closed toy‑box package behind it with illustrated box art matching the figure.”

Pet figurine
“Turn the uploaded pet photo into a realistic 1/7 scale figurine with expressive eyes and detailed fur, on a clear acrylic base, lit by warm studio lights, with a mini package box showing flat artwork of the pet.”

Pro tips for consistency
Keep the base constant (round, transparent, no text) to avoid unwanted labels.
Specify lighting (softbox, warm lamp, rim light) for clean highlights and fewer artifacts.
Iterate with short corrective instructions: “same face, adjust pose to sitting,” “reduce gloss on jacket,” “increase box art contrast.”
If likeness degrades, switch to a higher‑quality source photo and simplify style instructions
