The first time most people pose for professional headshots is for school photos—dressed up, posed against a featureless background, and told to smile. Today, professional photo shoot results can be achieved without a photographer, and even without a formal photo session, thanks to AI. Google's Gemini Nano Banana 2 makes it possible to turn casual selfies into polished headshots that rival traditional corporate photography, all in minutes and at little to no cost.

ZDNET's key takeaways

• AI can turn casual photos into polished portraits with the right prompts.
• Prompt tweaks control lighting, style, and wardrobe.
• Results rival traditional corporate headshots.

The first time most of you posed for professional headshots was for school photos. You got dressed up (as best you could when at grade school, high school, or college), posed in front of a featureless background, and tried to smile. Many people have similar experiences—yearbook photos, book jackets, corporate portraits. In each case, the photographer was expensive, and the experience was often difficult. The most productive headshot sessions involved patient photographers who guided subjects toward the perfect shot. Today, AI eliminates the need for that expensive setup.

Recently, ads for AI headshot services have been appearing on social media, promising professional results for a fee. But you don't need to pay a random AI service. Using Google's Gemini Nano Banana 2, you can create professional headshots for free (or as part of the $20 Google AI Pro plan). The free tier may require waiting a few hours between generations, but it's perfectly viable for patient users.

How to create professional headshots with Gemini

The key to success lies in a well-structured prompt. A simple prompt like "make this look professional" often yields generic results. Instead, break your prompt into three parts: subject description, environment specification, and camera/lens style. This ensures the AI preserves your facial features while adjusting expression, clothing, background, and lighting.

Building the perfect prompt

Here is the three-part prompt used in the examples below:

• Subject: "Produce a hyper-realistic, formal portrait depicting the subject in a dark navy suit. Preserve the exact same facial features and hairstyle from the reference image. The expression should convey powerful confidence and composure, with a subtle sense of authority and intelligence."
• Environment: "Use refined, dramatic lighting, soft studio illumination with delicate shadows that define and enhance facial contours. The background should feel understated yet upscale, such as charcoal, deep taupe, or a smooth black gradient."
• Camera style: "Capture the image in a premium editorial style with crisp focus and cinematic depth of field, as if shot on an 85mm lens. Ensure extremely high detail, consistent with a polished corporate portrait and luxury brand aesthetic."

Combine all three parts into a single prompt. The AI will generate a headshot that retains your identity but upgrades the overall look.

First test: Transforming Steven's selfie

The first test subject provided a casual selfie with a nice smile. Using the three-part prompt, the AI generated a studio-quality portrait. The expression changed from a grin to a confident, corporate look, but the facial features remained clearly recognizable. The background became a smooth gradient, and the lighting modeled the face effectively.

After the initial result, the tie was adjusted with a follow-up prompt: "Convert the tie to a red regimental stripe tie. Keep everything else identical and unchanged." The AI handled this precise instruction well, changing only the tie pattern.

For fun, a second creative prompt was used: "Dress the subject as if he's the star performer of a metal band, but don't change his face or use facial makeup. Make the post appropriate for a publicity shot for an album. Make his T-shirt say Linux. Have electricity shoot out of the top of the guitar, but don't obstruct the subject." The resulting image was playful yet maintained the subject's identity.

Second test: Artie Beaty's transformation

The second test subject provided three snapshots. The highest-resolution image included another person. The first step was to isolate the subject using a prompt: "Remove the woman from the image and make the man face forward and centered. Preserve the exact same facial features and hairstyle from the reference image." This worked well, producing a centered solo portrait.

Next, the same three-part corporate prompt was applied. The AI returned a headshot with a classic crossed-arms pose, professional lighting, and a navy suit. Again, a red regimental tie was added with a simple follow-up prompt.

For a creative twist, the subject's interest in ghost tours inspired a Ghostbusters-themed prompt. The AI produced a convincing publicity shot, and a further prompt to change the name to "BEATY" resulted in perfect text rendering, with letters appearing embroidered onto the uniform.

Why AI headshots are worth trying

These examples demonstrate that AI-generated headshots can match or exceed the quality of traditional photography for many use cases. The process is fast, inexpensive, and highly customizable. You can adjust backgrounds, attire, and even add thematic elements. The ability to refine specific details—like changing a tie or removing a person from the frame—gives users control that a traditional photo shoot might not offer without retouching costs.

However, AI is not perfect. Some results may require multiple attempts, and certain details like hand placement or accessories might need correction. The AI also adds a small logo to generated images, which can be cropped or removed with basic editing tools. Despite these minor limitations, the technology is powerful enough to replace traditional headshot sessions for many professionals.

Tips for best results

• Start with a clear, well-lit selfie with good resolution.
• Be specific in your prompts: describe clothing, expression, lighting, and background.
• Use follow-up prompts to tweak details without regenerating the entire image.
• Experiment with different styles (corporate, creative, casual) to see what works best.
• If using the free tier, be patient between generations.

There is no reason to pay premium prices to AI headshot services advertised online. With tools like Gemini Nano Banana 2, anyone can create professional-looking photos from the comfort of home. The prompts provided in this article serve as a starting point—feel free to adjust them to match your preferences. Whether you need a LinkedIn profile picture, a company bio headshot, or a fun themed portrait, AI makes it possible with minimal effort.
