How to create a hyper-realistic 1/7 PVC figurine image with Google Nano-Banana

Nano-Banana (the image/editing model in Google’s Gemini family) excels at high-quality image editing and text→image generation. Start by preparing a clean, high-resolution reference photo of your subject (front or half-body). Upload it to Gemini/A-I Studio and use Nano-Banana’s editing mode to guide the model to “turn the photo into a 1/7 scale PVC figurine” while keeping facial details identical. (Gemini)

Step 1 — prep the reference: crop and lightly retouch the photo so the face is clear and evenly lit. If the photo is half-body, note clothing colors, textures, and any held objects — the model will extend missing legs and footwear to match. Clear references reduce hallucination. (DEV Community)

Step 2 — craft the prompt: use a long, specific prompt that covers scale (1/7), material (PVC), base (round transparent acrylic), environment (computer desk indoors), and the three synchronized elements (final figurine, ZBrush process on the monitor, and the BANDAI-style packaging art). Include “100% accurate facial details — no changes” to prioritize face fidelity. The detailed prompt below is optimized for Nano-Banana.

Step 3 — run edits, iterate: in the Gemini UI or API, submit the reference plus your prompt. Start with a smaller resolution draft, inspect face fidelity and clothing match, then request higher-resolution renders. Use the model’s “edit” mode if you want to preserve exact facial pixels while changing other things to figurine style. (Google AI for Developers)

Step 4 — polishing & post: output an image at the highest available resolution. If needed, perform tiny retouching in an image editor (sharpening, contrast) or rerun Nano-Banana instructing it to “increase PVC sheen, keep face identical.” If you plan to 3D print or actually manufacture, use the ZBrush screen content as a reference for a sculptor or a 3D-artist export.

Best practices: always keep an unedited backup of the original photo; lock the face region in the prompt instructions; iterate quickly and keep prompts reproducible. Community tutorials and the official developer guide are excellent references while you tune parameters. (DEV Community)

Final Refined Prompt (use as-is)

Create a hyper-realistic photo of a 1/7 scale commercialized PVC figurine, using the nano-banana model, based on the uploaded photo.

- Full-body completion:
  - If the uploaded photo is half-body, extend and generate the missing parts naturally: legs, outfit, and footwear that match the upper outfit design, colors, and style.
  - Ensure gender, proportions, and clothing continuity remain consistent with the original.

- Include all elements:
  - If the photo has multiple persons, animals, or objects being held, include all of them in the figurine design.
  - Preserve their positions, details, and proportions, stylized in realistic PVC figurine form.

- Display setup (all synchronized):
  - Place the figurine on a computer desk indoors.
  - The figurine stands on a round transparent acrylic base (no text or logos).
  - On the computer screen, show the ZBrush modeling process of the exact same members/characters/objects from the uploaded photo.
  - Next to the monitor, position a BANDAI-style toy packaging box featuring two-dimensional flat illustrations of the same characters/objects.
  - In front of the box, display the completed figurine version of the uploaded photo on its acrylic base.

- Quality & realism:
  - The figurine must have 100% accurate facial details, perfectly matching the uploaded photo (no changes to faces, eyes, noses, lips, or smiles).
  - PVC material should look realistic, with painted details, shading, and polished texture.
  - The background should feel like a realistic indoor desk setup, captured in high resolution, Sony camera quality, with natural lighting and depth of field.

Here is the simple prompt copy it manually:

Create a 17 scale

commercialized figurine of the characters in the picture, in a realistic style, in a real environment.

The figurine is placed on a computer desk. The figurine has a round transparent acrylic base, with no text on the base. The content on the computer screen is a 3D modeling process of this figurine. Next to the computer screen is a toy packaging box, designed in a style reminiscent of high-quality collectible figures, printed with original artwork. The packaging features two-dimensional flat illustrations. Make the 3D figures look super realistic and real sculpture.
