Nano Banana 2 as Design Assistant: Storyboards, Batch Edit, Multi-Size
The right way to use Nano Banana 2: treat it as a “design assistant that understands plain language.” It can do storyboards in one go, batch retouch for a unified look, and adapt to multiple aspect ratios. This post shares copy-paste e‑commerce prompt templates and examples.
24-panel storyboards in one go
Specify three things: how many panels (e.g. 20/48/80), target audience and pain points, and what you’re selling (key benefits/differentiators). Then you’re not “writing prompts” but “giving briefs and reviewing.” Template: Generate ad storyboards for macbook neo product benefits, photorealistic, 24-grid, multiple colorways, sleek, close-up, detailed. Or: For Xiaomi car vision Gran Turismo, generate 12-panel ad storyboards, photorealistic, city night/highway/interior tech, highlight smart cabin/safety/control/range/space. You can also feed a competitor URL and ask for a detail page in that style (e.g. Apple-style for Dajiang mini 5 pro). Amazon listing: Generate 6 Amazon images for this tent (hero, scene, selling points, materials, size).
Batch retouch product images
Upload many product images and describe in plain language: unified shadow direction, cleaner reflections, harder metal feel, sharper edges, clean light-gray studio background. Template: Batch retouch uploaded product images: light gray studio background; keep proportion and structure; sharper edges; better metal/plastic texture; clean reflections; unified shadow direction and strength; consistent color; no over-smoothed skin, no change to product details. Result: 100 images that look like one studio shoot.
Multi-size output
One asset set for 1:1/4:5 hero, detail long图, 16:9 feed, or 8:1 banner. Template: Extend and adapt current asset to ratio 8:1. Keep subject undistorted and key elements uncropped; extend background naturally; keep text readable; style consistent with original.
