Best Nano Banana Portrait Prompts

Portrait prompts are the highest-volume category on NB Prompts, and they're where Google Gemini's Nano Banana model shines. The prompts in this collection have been tested across editorial, candid, and studio setups, and they produce consistent, photo-real faces with clean skin texture, natural eye light, and believable shadows. Pair them with a clear reference image when you need a likeness match, or run them text-only when you want a fresh subject. We refresh this collection monthly based on real copy activity, so what you see here is the working list — not a marketing curation. If a prompt isn't producing the output you want, try changing the lens (50mm vs 85mm), the lighting (north window vs softbox), or the mood word (candid vs cinematic) — small wording shifts produce dramatic output changes.

Every prompt below is free to copy and free for commercial use. Click the title to open the full prompt page, where you'll find example outputs, model recommendations, and tips for adapting the prompt to your subject.
