Try the Portrait GeneratorThe gap between "AI-generated" and "real photograph" has nearly vanished. Models like Nano Banana Pro and Flux 2 now produce portraits indistinguishable from professional studio shots. Yet most people still get plasticky, uncanny valley results.
The difference isn't the tool — it's the technique. This guide covers the exact prompts, settings, and methods that produce professional-quality AI portraits every time.
Before fixing the problem, understand what causes it. Three issues create the "AI look":
Vague prompts. "A portrait of a woman" gives the AI too much freedom. It fills in gaps with average, generic features that trigger our uncanny valley response.
Style mixing. Requesting "photorealistic painting" or "realistic anime portrait" confuses the model. These are contradictory instructions.
Wrong technical specs. Real portraits have specific characteristics: shallow depth of field, particular focal lengths, consistent lighting direction. Missing these signals screams "fake."
Professional photographers think in terms of subject, lighting, lens, background, and post-processing. Your prompts should too.
Be specific about age range, features, and expression. "Young woman" is weak. "Woman in her late 20s with freckles, auburn hair pulled back, slight confident smile" gives the AI concrete details.
Include:
Lighting makes or breaks realism. Reference actual photography lighting:
This is the secret most people miss. Real portrait photographers use specific gear that creates recognizable characteristics:
Include phrases like "shot on 85mm lens, f/1.8, shallow depth of field" to trigger these characteristics.
Keep backgrounds simple for headshots. Specify:
Busy backgrounds compete with the subject and often introduce artifacts.
End your prompt with quality signals:
Equally important: what NOT to include. Avoid:
Professional headshot of a man in his early 40s with short gray-streaked hair and warm brown eyes, wearing a navy blazer over white shirt, confident friendly expression, Rembrandt lighting, shot on 85mm lens f/1.8, shallow depth of field, neutral gray studio backdrop, 8K, detailed skin texture, professional corporate photography
Natural portrait of a young woman in her mid-20s with curly dark hair and green eyes, genuine relaxed smile, wearing cream knit sweater, golden hour natural light, outdoor setting with soft bokeh background, shot on 85mm lens f/2.0, warm tones, lifestyle photography, high detail
Editorial fashion portrait of an older woman in her 60s with silver hair and striking blue eyes, elegant confident expression, dramatic side lighting, minimalist composition, shot on medium format camera, shallow depth of field, dark studio background, high-end magazine photography, 8K resolution
Portraits work best in vertical orientations:
Avoid square (1:1) for traditional portraits — it feels unnatural for headshots.
For photorealism, Nano Banana Pro currently leads the pack. Its understanding of lighting physics and skin texture is unmatched for portrait work. Flux 2 Pro is another excellent option, particularly strong with complex lighting scenarios.

Over-prompting. More words isn't always better. A focused 50-word prompt often beats a rambling 200-word one. Include what matters, skip the rest.
Mixing photorealistic with artistic styles. Pick one. "Photorealistic oil painting portrait" produces neither good photos nor good paintings.
Ignoring lighting consistency. If you specify "Rembrandt lighting" but also "bright even lighting," you've given contradictory instructions.
Forgetting the eyes. Eyes sell portraits. Include "sharp focus on eyes" or "catchlights in eyes" to ensure this critical detail renders well.
Wrong aspect ratio. Horizontal portraits feel like landscapes with a person in them. Go vertical for headshots.
The techniques above work across any AI image generator. But having the right tool matters too.
PixelMuse's AI portrait generator is built specifically for this use case — optimized prompts, correct aspect ratios, and access to Nano Banana Pro for maximum realism.
