Generate Studio-Quality E-commerce Product Main Images with Nano Banana Pro API: 3 Steps to Transform Selfies into Professional Main Images + Smart Background Replacement

One of the biggest headaches in e-commerce operations is the high cost, long turnaround times, and inconsistent quality of product photography. A standard set of studio-quality main images—covering everything from lighting and shooting to post-processing—can easily cost thousands of dollars and take 3-5 business days. Now, Nano Banana Pro API can turn a mobile snapshot or a 3D model render into a studio-grade e-commerce main image in under 10 seconds, complete with multi-angle generation and intelligent background replacement.

Core Value: By the end of this article, you'll master three core techniques for using the Nano Banana Pro API to handle the entire workflow—from "quick snap/3D model" to "e-commerce main image + multi-angle + background replacement"—slashing your product image production costs by 90%.

Nano Banana Pro E-commerce Main Image: Core Capabilities at a Glance

Before we dive into the hands-on guide, let's look at the five core capabilities of Nano Banana Pro (based on Gemini 3 Pro Image) for e-commerce product photography.

🎯 Technical Tip: Nano Banana Pro supports up to 8 reference images simultaneously (double the standard version), making it perfect for maintaining consistency across multi-angle e-commerce images. You can quickly call this model via the APIYI (apiyi.com) platform without needing to configure your own Google Cloud environment.

Nano Banana Pro: A 3-Step Guide to Generating E-commerce Main Images

Step 1: Transforming Product Selfies into Studio-Grade Main Images

This is the most common scenario—you've got a casual product photo taken with your phone, and you need to turn it into a standard e-commerce main image with a clean white background and studio-quality lighting.

Core Prompt Template:

Transform this product photo into a professional e-commerce product shot.
Clean studio lighting with soft key light from upper-left, fill light from right.
Pure white background (RGB 255,255,255).
Remove all fingers, hands, and background clutter.
Add subtle natural contact shadow at the base.
Product centered, occupying 80% of frame.
4K resolution, commercial photography quality.

Minimalist Code Example:

import base64
import re

client = openai.OpenAI(
    api_key="YOUR_API_KEY",
    base_url="https://api.apiyi.com/v1"  # Using the APIYI unified interface

        "content": [
            {"type": "text", "text": "Transform this product photo into a professional e-commerce product shot. Pure white background, studio lighting, remove background clutter, add contact shadow. 4K resolution."},
            {"type": "image_url", "image_url": {"url": "YOUR_PRODUCT_PHOTO_URL"}}
        ]
    }]
)

# Extract Base64 image data from the response and save it
content = response.choices[0].message.content
match = re.search(r'data:image/[^;]+;base64,([A-Za-z0-9+/=]+)', content)

Optimization Tips for Selfie-to-Studio Conversion:

Step 2: Converting 3D Renders to Photorealistic E-commerce Shots

If you have 3D models of your products (like industrial designs, furniture, or 3C gadgets), you can transform those renders into "real-life" e-commerce main images, stripping away that artificial CG look.

3D-to-Realism Prompt Template:

Convert this 3D rendered product into a photorealistic e-commerce product photograph.
Add realistic material textures: subtle surface imperfections, accurate light reflections.
Studio photography lighting setup: key light 45° upper-left, rim light from behind.
Pure white background with soft gradient at edges.
Add micro-details: slight dust particles in light beam, realistic contact shadow.
The result should be indistinguishable from a real studio photograph. 4K resolution.

Key Tip: Asking the AI to add real-world "micro-imperfections" (like dust particles in the light or subtle surface texture variations) is the secret to eliminating that CG feel.

Optimization Parameters for 3D-to-Realism

💡 Pro Tip: Nano Banana Pro can also transform 2D product images into shots with 3D visual depth—perfect for products that don't have 3D models yet. Just specify your target perspective (e.g., 45-degree perspective view), and the model will infer a realistic 3D perspective from your flat photo.

Step 3: Multi-Angle Image Sets + Smart Background Replacement

E-commerce platforms usually require 5-8 main images showing different angles and scenarios. Nano Banana Pro’s multi-image input capability (up to 8 reference images) ensures product consistency across all angles.

Multi-Angle Generation Strategy:

# Multi-angle Prompt Configuration
ANGLE_PROMPTS = {
    "Front Main": "Front view, straight-on angle, eye level. Pure white background. Studio lighting.",
    "45-Degree": "45-degree angle from upper-right. Show depth and form. Pure white background.",
    "Side View": "Left side profile view. Highlight side panel details. Pure white background.",
    "Top-Down": "Top-down overhead view. Show top surface layout. Pure white background.",
    "Lifestyle": "Product placed on modern desk, natural daylight from window, lifestyle photography."
}

# Generate each angle sequentially
for angle, prompt in ANGLE_PROMPTS.items():
    full_prompt = f"Professional e-commerce product shot, {prompt} Product must match the reference exactly. 4K resolution."
    generate_product_shot(product_url, full_prompt, f"angle_{angle}")

Smart Background Replacement Template Library:

🚀 Quick Start: We recommend using the APIYI (apiyi.com) platform to call the Nano Banana Pro API. It saves you the hassle of Google Cloud environment configuration and provides an OpenAI-compatible interface—you can integrate it by changing just one line of base_url in your existing code.

Nano Banana Pro E-commerce Main Image Prompt Engineering Best Practices

Mastering prompt engineering is the key to leveling up your e-commerce main images. Here's a breakdown of the prompt writing standards we've developed after extensive testing.

The Prompt Structure Formula

A high-quality e-commerce main image prompt should include 6 core elements:

[Product Action] + [Perspective/Angle] + [Lighting Setup] + [Background Requirements] + [Detail Control] + [Output Specs]

Real-world Example:

Transform this handbag photo into a professional e-commerce hero image.    [Action]
Front-facing view, slightly elevated camera angle (15° above eye level).   [Perspective]
Three-point studio lighting: key light 45° upper-left at 5600K,           [Lighting]
fill light right at 4800K, rim light behind for edge separation.
Pure white background (RGB 255,255,255) with soft vignette at corners.    [Background]
Enhance leather texture details, show stitching clearly,                   [Details]
accurate metal hardware reflections.
4K resolution (4096x4096), commercial photography standard.                [Output]
