Multi‑image fusion & compositing: Overcome multi‑subject limits with Nano Banana

What it does

When a complex scene requires multiple specific people or objects, one‑shot generation often falls short. Multi‑image fusion lets you compose a labeled collage as reference, then produce a cohesive, realistic scene with correct lighting, perspective, and scale.

How it works

  1. Prepare separate images for each subject (model, product, background, pet, etc.).
  2. Optionally create a labeled collage as layout reference.
  3. Upload everything and describe relationships/placement in the prompt.
  4. Generate, iterate, and export.

Prompt example (using a labeled collage)

A man is standing in a modern electronics store analyzing a digital camera. He is wearing a watch. On the table in front of him are sunglasses, headphones on a stand, a helmet, and a white sneaker. Use the labeled collage as a reference for all items. Style: realistic commercial photography.

Tip: For best results, pre‑compose a collage that includes all subjects and add simple labels (e.g., “white sneaker”), then reference those labels in your prompt.

Why it matters

  • Precisely control multi‑subject scenes by composing first, then generating.
  • Explore creative combinations fast — no complex shoots or manual compositing.
  • Significant cost/time savings for ads and catalogs; “a one‑person team” capability.
