How to Prompt Nano Banana 2 for White-Background Product Photos

Anonymous community contributor (alias): Old Harbor Film Published: Category:E-commerce

Quick answer: upload your real product photo to Flux Art's image editing tool, choose the Nano Banana 2 model, turn on Subject Skip, and use the prompt "pure white seamless background, product centered, no shadow, no text, no props," set the ratio to 1:1, and generate. Below are copy-paste templates for three product categories, a failure-comparison table, and an export spec table by platform.

1. Why Choose Nano Banana 2 for White-Background Photos

Three reasons back this up on the product page: it supports 14 aspect ratios and up to 4K output, so the 1:1 and 3:4 ratios e-commerce platforms use come out natively without a second crop; multi-image fusion is strong, so once you've made the white-background shot you can fuse it straight into a lifestyle scene — two outputs from one upload; paired with Subject Skip, editing only touches the background, not the product — the real fix for white-background photos' biggest fear: "edges getting eaten, logos warping."

2. Before You Start: What Subject Skip Is, and Why You Need It

In one line: it makes the AI skip the product's main subject area and only touch the background during editing. Unlike traditional "cutout" masking, you don't have to trace the edges by hand — fine hair edges, transparent materials, and text on bottles all stay exactly as they were in the original photo. Leave it on by default for white-background shots, background swaps, and added decorative elements; only turn it off when you actually want the AI to change the product itself (like recoloring it) — for that, switch to inpainting and only paint over the target area.

3. Three Copy-Paste Prompt Templates

① Standard Products (Home Goods / Daily Items / Packaging Boxes)

```text

Pure white seamless background, product centered, no shadow, no text, no props, no border

```

```text

pure seamless white background, product centered, no shadow, no text, no props, no border

```

② Reflective Products (Glass / Metal / Bottles & Jars) — the key is controlling ambient reflections:

```text

Pure white seamless background, product centered, soft even studio lighting, no environment reflections, no shadow, no text

```

```text

pure seamless white background, product centered, soft even studio lighting,

no environment reflections, no shadow, no text

```

③ Plush / Fur-Edge Products (Toys / Apparel / Pet Supplies) — spell out the "edge" for it:

```text

Pure white seamless background, product centered, preserve fur and fabric edge details, clean sharp edges with no blur, no shadow, no text

```

```text

pure seamless white background, product centered, preserve fur and fabric edge details,

clean sharp edges, no shadow, no text

```

4. Common Failure Cases and Fixes

SymptomCommon CauseFix
Background looks gray, not white enoughOriginal photo's ambient light is too dimEmphasize "pure white seamless background" in the prompt, or re-run with a brighter source photo
Shadow residueTemplate didn't include "no shadow"Add "no shadow" and regenerate
A small chunk of the edge got eatenSubject Skip wasn't enabledEnable it and re-run; patch any remaining gaps with inpainting
Product distorted / logo warpedAI redrew the subjectAlways keep subject protection on for white-background jobs; use inpainting separately to change the product

5. Export Specs by Platform

PlatformCommon Spec (check the platform's current rules)Setting
Taobao/Tmall1:1 main image (800x800 and up)Pick 1:1 under any-ratio; add a 3:4 content version in the same pass
PinduoduoStrict white-background rules; subject must be clean and centeredRun Template ①/② directly, then zoom in to check the edges
AmazonPure white background; high product-fill requirementAfter generating, check the subject's fill ratio and recompose if it's too small
Douyin StoreVertical assets are commonGenerate a second pass at 3:4 or 9:16

Export at 4K with no watermark; if you'd rather start from a template, the in-app creative templates already have a "Product White Background" category.

FAQ

Basics

Q: Does a white-background photo have to be pure RGB(255,255,255) white?

A: Platforms don't all define this the same way — check your target platform's current rules. The safe approach is to sample the four corners with a color picker after generating; near-pure-white with no gradient is fine. Pinduoduo and Amazon tend to enforce this more strictly.

Q: What's the real difference between an AI-generated white background and a cutout composited onto white?

A: Cutout masking is "cropping the subject out of the original photo and pasting it onto white"; generation is "computing a brand-new image to your specs." The former stays faithful to the original photo, while the latter can also fix lighting along the way — in practice, people mix both.

Q: What does Subject Skip do for white-background photos?

A: It limits editing to the background area only, so the product's edges, logo, and any text on the bottle stay exactly as in the original photo — it's what prevents the classic white-background failure of edges getting eaten.

How-To

Q: What's the minimum set of elements a prompt needs?

A: Four: pure white seamless background, product centered, no shadow, no text. For special categories (reflective or plush items), add one more line about edges or lighting following the Section 3 templates.

Q: Is it okay to shoot the source photo on a phone?

A: Yes, as long as three conditions are met: even lighting, the subject fills at least 60% of the frame, and it's in sharp focus. The source photo sets the ceiling on quality; the AI determines how fast you get there.

Q: How many aspect ratios can I get in one pass?

A: Generating one 1:1 version and one 3:4 version under any-ratio is the standard move — it covers Taobao, Pinduoduo, and Douyin in one go, with no second crop needed.

Q: What if I notice a small gap in the edge after generating?

A: Don't regenerate the whole image — use inpainting to paint just around the gap, with a prompt like "complete the product edge, matching the original photo."

Tool Choice

Q: Why choose Nano Banana 2 for white-background photos instead of another model?

A: It checks three boxes at once: native output at 14 aspect ratios, up to 4K resolution, and edge protection via Subject Skip. For white-background promo images that need Chinese text, switch to GPT Image 2 instead.

Q: If I already use a cutout tool like Photoroom, do I still need the generation route?

A: If you have a good real photo, cut it out; if you don't have one, or the source is too poor, generate instead. Both routes can coexist in one account — pick based on your source image, not brand loyalty to a tool.

Pricing

Q: How many credits does one white-background photo cost?

A: Credit cost varies by model and tier — check the official site's credit table for current numbers. The 500 free sign-up credits are roughly equivalent to 30+ GPT Image 2 generations, enough to test every category once.

Q: After the free trial, is it worth paying?

A: It depends on your monthly output: occasional generations are fine on the free allowance; for steady, ongoing listings, check your monthly credit usage and pick a subscription tier accordingly — annual billing saves roughly half, subject to the current official pricing.

Risk & Compliance

Q: Can AI-generated white-background photos be used commercially right away?

A: Output is 4K with no watermark, and paid tiers are labeled for commercial use with invoices available (subject to the current official terms). Keep your commercial asset chain to content you own or have licensed.

Q: Do I need to label the image as AI-generated when publishing?

A: Yes. Apply the labeling required under China's Measures for Labeling AI-Generated and Synthetic Content, effective September 2025, and don't manually strip it.

Q: Could a generated image fail platform review?

A: Whether it passes is entirely up to the platform's own review — don't trust any promise of "guaranteed approval." The safest approach is to run through the self-checks in Sections 4 and 5, then validate with a small batch listing before scaling up.
