How to Write a Headshot Prompt for Nano Banana

What Nano Banana Needs from Your Headshot

Picture this: you're a project manager at a tech startup called Nano Banana. Your profile photo isn't just for the company directory; it's on the "About Us" page for clients, in your email signature for vendors, and on the big screen at the quarterly all-hands meeting. They need a headshot that says "innovative but trustworthy," "friendly but sharp." A blurry selfie from your cousin's wedding, where you're holding a drink and squinting, won't cut it. They need a professional image that builds confidence in the brand, which means they need you to look approachable, competent, and like part of a cohesive team. Think clean background, good lighting on your face, and an expression that says you're the person who can solve problems.

Your 5-Point Prompt Checklist

Before you type a single word, run through this list. A strong prompt is a specific recipe, not a vague wish. Get these five things right.

• Who You Are: "A 35-year-old female software engineer" is better than "a professional woman." Include your real or perceived age, gender, and role.
• Face & Expression: This is the core. We'll break this down next. For now, know you need more than "smiling."
• Shot Type & Angle: Specify "head and shoulders portrait," "close-up headshot," or "three-quarter length." Say "camera angle at eye level" or "slightly from above."
• Lighting & Quality: Use terms like "soft, even studio lighting," "catchlights in the eyes," "no harsh shadows," "professional photography." This kills the phone-selfie look.
• Background & Style: "Clean, light gray seamless backdrop," "modern office environment with shallow depth of field," "corporate headshot style."

Describe Your Face & Expression Precisely

Here’s where most prompts fail. "Friendly smile" could mean a closed-mouth grin or a toothy laugh. You must be a poet of the face. Let's get concrete. Are your eyes "engaged and directly at the camera" or "softly focused, looking slightly off-frame"? Is your smile "warm with a slight crinkling at the corners of the eyes" or "a confident, closed-lip smile showing no teeth"? Describe your face shape if it matters: "oval face with a strong jawline." Mention your hair: "short, curly brown hair styled neatly." I once had a client who said "give me a 'listening' face." We got a slight head tilt, relaxed eyebrows, and a very subtle, attentive smile. It was perfect for his consultant profile. That’s the level of detail you need.

Avoid These Three Vague Prompt Mistakes

First, ban the word "professional." It means nothing. Does it mean a suit? A lab coat? A polo shirt? Say "wearing a navy blue blazer over a light blue dress shirt" instead. Second, avoid emotional adjectives without a physical anchor. "Approachable" becomes "a genuine smile that reaches the eyes." "Confident" becomes "standing tall with shoulders back, a direct gaze, and a slight, assured smile." Third, never use "normal" or "regular." One person's normal haircut is another's mohawk. I saw a prompt that asked for "a normal guy." The result was so bland and forgettable it hurt. Be boldly, specifically you.

From Good Prompt to Great Profile Photo

You've written a solid prompt: "A 40-year-old male project manager with a short beard, wearing a charcoal gray sweater. Close-up headshot with soft studio lighting, a genuine, closed-lip smile with visible kindness in the eyes, against a blurred modern office background." That's good. To make it great, add one layer of context. Why are you smiling? What just happened? Try this: "A 40-year-old male project manager with a short beard, wearing a charcoal gray sweater. Close-up headshot with soft studio lighting. He has the expression of someone who just heard a team member's great idea—a warm, approving smile that reaches his eyes, looking directly at the camera as if connecting with a colleague. Blurred modern office background." That tiny story changes everything. It gives the expression a reason to exist, making it feel real and alive.

Your headshot is a handshake people see before they meet you. A precise prompt is the instruction for that handshake—firm, warm, and exactly right for the room you're walking into. Spend fifteen extra minutes on the details now, and you'll have a photo that works for you for years.
