How to Make Nanobanana 2 Generate Low‑AI‑Feel Portraits That Look Like Casual Phone Shots

Why Many AI‑Generated Beauty Images Look Wrong

Reon observes that models like Gemini Nanobanana tend to produce images with overly smooth skin, flat texture, perfect lighting, and flawless composition, which lack the natural breath and imperfection of real photos.

Core Insight: Reduce the "AI Feel" Instead of Adding More Glamour

The goal is not to make the image more dazzling, but to make it resemble a casual phone selfie.

Unified Prompt Principles

Although ten different prompts are provided, they share a consistent structure that can be distilled into a set of guiding rules.

1. Pin Down the Shooting Medium

Specify the camera type explicitly, e.g.:

Photorealistic smartphone selfie

smartphone photo

mirror selfie

smartphone snapshot

Without this, the model defaults to commercial‑style portraits.

2. Keep the Scene in a Private Space

Use stable, personal environments such as bedroom, bedside, mirror, closet, or any "at home" setting. This makes the lighting, pose, and background easier to justify and more believable.

3. Choose Light, Soft, Home‑Style Clothing

Typical descriptors include:

sports bra

lounge shorts

casual indoor shorts

relaxed home clothing

The intent is to avoid overly designed outfits and to convey a genuine, lived‑in feel.

4. Use Subtle, Slightly Intimate Poses

Common phrasing:

slightly raises one shoulder

slightly leans forward

cute playful pose

subtly sexy pose

slightly shy pose

This prevents the model from pushing the image toward extreme commercial or artificial aesthetics.

5. Insist on Natural Daylight

Preferred lighting terms:

bright natural daylight

natural window light

soft daylight

bright indoor daylight

Natural light grounds the scene in realism and avoids the "too‑pretty" cinematic look.

6. Actively Remove Background Noise

Typical exclusions added to prompts:

no posters

no photos

no books

simple bedroom background

clean room environment

By limiting decorative elements, the model has less room to hallucinate irrelevant objects.

Prompt Formula Summary

Specify smartphone/selfie shooting mode

Place the subject in a credible private setting (bedroom, bedside, home)

Give concrete age and hairstyle details

Dress the subject in lightweight, home‑style clothing

Adopt a lightly intimate pose

Use natural daylight lighting

Simplify background and exclude posters/photos/books

This formula is not a single prompt but a stable generation strategy.

Final Thoughts from the Author

Reon notes that while Nanobanana is powerful, it is also one of the hardest models to control for realistic portraits; newer models like Grok may yield more immediately satisfying results for beginners.

The overarching lesson is that achieving realism is less about adding glamorous descriptors and more about constraining the scene, lighting, and pose to match everyday phone photography.
