How to Build a Consistent Product Mockup Set with Seedream 4.0
The hard part of AI product imagery is not any single good picture. It is eight pictures that look like they came from the same shoot. Seedream 4.0 handles this with reference images, and the workflow is specific enough to be worth writing down.
This is for small e-commerce teams and solo marketers shipping a campaign without a photographer.
Why reference images matter more than prompts
Prompts describe intent; references lock appearance. If you describe a bottle in words twice, you get two different bottles. If you attach the same reference image twice, you get the same bottle in two settings. Seedream accepts up to four reference images per request, so the practical setup is one product shot plus up to three scene references.
How do you set up the first shot?
Start with your cleanest existing product photo, ideally on white with even lighting. Ask for the hero image first and inspect it closely.
- Check that logo placement and label text survived
- Check proportions against your real product
- Save this output as your canonical reference
Every later shot should reference this canonical image rather than the original photo, so the lighting and colour treatment stay consistent.
How do you produce the rest of the set?
For each scene, attach the canonical image plus a background reference, then describe only the change. Keep the wording for the product identical across every prompt. That repetition is doing the consistency work.
| Shot type | Reference images | Prompt focus |
|---|---|---|
| Lifestyle | Canonical + scene photo | Surface and lighting only |
| Flat lay | Canonical + layout sketch | Arrangement of props |
| Packaging | Canonical + box mockup | Label text, quoted exactly |
| In use | Canonical + hand reference | Scale and grip |
What still needs retouching?
Label text on curved surfaces, like a bottle or tube, still distorts lettering enough that a designer should overlay the real logo in a separate editor. Reflections sometimes appear where physics says they should not. And colour drift creeps in across a long set, so compare the eighth image to the first before publishing.
What does this replace, and what does it not?
It replaces the mood-board and the low-stakes lifestyle shot. It does not replace a real shoot for a hero image on a homepage, where buyers will scrutinise the product. Treat the AI set as campaign filler and social content, and keep one genuine photographic hero per product. The cost argument holds at roughly a tenth of a studio day, but only if you accept the retouching pass.
Key Takeaways
- Consistency comes from reusing a canonical reference image, not from prompts.
- Seedream 4.0 accepts up to four reference images per request.
- Keep the product wording identical across every prompt in the set.
- Curved-surface label text and reflection artefacts still need retouching.
- Use the AI set for campaign and social content, not the homepage hero.
