The first time most people pose for professional headshots is for school photos. You get dressed up, stand in front of a featureless background, and try to smile. But times have changed. Today, professional photo shoot results can be achieved without a photographer, and even without posing for a formal shoot—thanks to artificial intelligence.

Recently, ads have been appearing across social media platforms promising cheap AI-generated headshots. While some services charge a fee, you can achieve similar results for free using Google’s Gemini Nano Banana 2. This guide shows how to create polished portraits from casual snapshots in minutes, with full control over lighting, style, and wardrobe.

The setup: Two test subjects

Two volunteers provided their candid photos for testing. The first subject offered a single image with a nice smile. The second subject contributed three shots; the highest-resolution image (taken with his wife) was selected for editing. The goal was to transform these casual photos into studio-quality headshots suitable for LinkedIn, corporate websites, or professional portfolios.

Crafting the perfect prompt

A single three-part prompt was used to achieve the first portrait. The prompt instructed the AI to preserve the subject’s exact facial features and hairstyle while altering the expression to convey confidence and authority. It specified a dark navy suit, refined dramatic lighting with soft shadows, and an understated upscale background such as charcoal or deep taupe. The final part described a premium editorial style with crisp focus and cinematic depth of field, as if shot on an 85mm lens.

The AI returned an image that clearly maintained the subject’s identity. The expression shifted from a grin to a composed, corporate look. The suit and lighting created a classic professional aesthetic.

Fine-tuning the wardrobe

After the initial result, a simple follow-up prompt was used to change the tie to a red regimental stripe tie, keeping everything else identical. The AI executed the change flawlessly, demonstrating the ability to tweak small details without affecting the overall image.

Adding personality

For fun, the subject was transformed into a rock star. The prompt asked the AI to dress the subject as the star performer of a metal band, keep the face unchanged, and add a guitar with electricity shooting from the top. The resulting image featured the subject in a band T-shirt reading “Linux,” complete with stage lighting and music-themed accessories.

Second test: From family snapshot to corporate headshot

For the second subject, the first step was to isolate him from his wife in the original photo. A prompt instructed the AI to remove the woman and center the man facing forward while preserving his features. The result was a clean solo portrait, though the lighting cast shadows over the eyes.

Rather than fixing the lighting directly, the same three-part corporate portrait prompt used for the first subject was applied. The AI returned a professional headshot with even lighting, a navy suit, and a confident expression. Again, a red regimental tie was added with a simple follow-up command.

A nod to pop culture

The second subject’s bio mentions leading ghost tours on weekends. A playful prompt asked the AI to dress him as a Ghostbuster while keeping his face unchanged. The AI produced an image with the subject in a jumpsuit and proton pack. However, the name “Spengler” appeared on the uniform. A correction prompt removed the patch and replaced the name with “BEATY.” The AI rendered the embroidered letters convincingly.

Why this matters

Professional headshots traditionally require booking a studio or photographer, paying hundreds of dollars, and spending an hour or more posing. AI tools like Gemini Nano Banana 2 eliminate these barriers. With a well-crafted prompt, anyone with a smartphone can generate images that rival those from a corporate photo session.

The technology also offers flexibility. Users can experiment with different outfits, backgrounds, and expressions without needing multiple physical sessions. This is especially valuable for remote workers, freelancers, and small business owners who need professional images on a budget.

Technical considerations

Gemini Nano Banana 2 generates images at high resolution with impressive detail. It handles text rendering surprisingly well, as seen with the custom name patch. However, the AI always adds a small logo to generated images. This can be removed with photo-editing software like Photoshop’s Content-Aware Fill.

For free-tier users, there may be a waiting period between generations. The paid Google AI Pro plan (around $20 per month) allows faster generation and unlimited prompts. But even the free version can produce excellent results with patience.

Prompt engineering tips

• Be specific about features: Explicitly instruct the AI to preserve facial features and hairstyle to maintain identity.
• Define the lighting: Use terms like soft studio illumination, dramatic shadows, or cinematic depth of field to control the mood.
• Specify wardrobe and background: Describe clothing colors and styles, and choose backgrounds that complement the subject without distracting.
• Iterate with follow-ups: Small changes (tie color, background texture) can be made with short prompts without regenerating the entire image.

The bigger picture

AI headshot generation is part of a broader trend of using generative AI for practical, everyday tasks. As the technology improves, it blurs the line between professional and amateur photography. Some photographers worry that AI will replace them, but many see it as a tool to streamline their work or offer new services.

Critics point out that AI-generated images can still have subtle artifacts—unrealistic skin textures, uneven lighting, or strange background elements. For social media and LinkedIn, however, these issues are often negligible. For high-stakes uses like passport photos or magazine covers, traditional photography remains the standard.

Nevertheless, the convenience and cost savings are undeniable. With a few minutes and a well-written prompt, anyone can have a headshot that looks like it was taken in a professional studio.

Have you tried using AI tools like Google Gemini to create professional headshots? How did your results compare to traditional photography? Do you think such prompts are enough to replace a photographer, or do they still fall short in some ways?
