Product Ad Hero Shot Prompt for Nano Banana (Gemini)
This is the Nano Banana (Gemini) version of the product ad hero shot prompt: a commercial hero image of a product with deliberate negative space reserved for ad copy. It is formatted the way Nano Banana (Gemini) takes prompts best. Free — copy it, replace the bracketed parts, and paste it in.
The prompt
Push copies this prompt with a reference line naming your image, and downloads the image file — attach it in the model to complete the pair. This page stages the pair for you; it cannot upload into the model itself (sites cannot reach into each other), so the final attach happens there. The image is downscaled to at most 1024px and stored only in this browser, paired with this prompt. If browser storage is full, it is kept for this visit only.
The deliverable — and how to check it
Deliverable: one hero product image, 16:9, product sharp in the left two-thirds of frame, the right third kept as clean negative space for copy. Acceptance check: the product's real proportions and materials read correctly at a glance, the copy space contains no objects, shadows or texture breaks, and no text or logo appears anywhere in frame (branding is added in post).

Using this prompt with Nano Banana (Gemini)
Nano Banana is Google's Gemini image family (the current flagship is the Gemini 3 Pro Image model). It takes conversational natural-language prompts — describe the image the way you would to a person, state the aspect ratio and resolution in prose or the app controls, and refine in follow-up turns: editing is multi-turn, so describe the change instead of rewriting the whole prompt. It accepts many reference images in one prompt (up to 14) — attach your keyframe and say what it controls. There is no negative-prompt field: to exclude something, describe what the image should show instead, or state the exclusion plainly in the instruction.
What this route costs — and how to pay less
Cost structure: bundled into Google's Gemini app and AI subscription plans (image generation included, with higher tiers raising limits), or metered per image through the Gemini API. If you already pay for a Google AI plan, this route may cost you nothing extra per image. The same prompt is pre-configured in this library for every major model, so you can run it on whichever route fits your budget — comparing the structures before you generate is a free way to save money.
Replace the bracketed placeholders — [PRODUCT], [SURFACE], [BACKDROP], [LIGHT DIRECTION] — with your own details before pasting.
