Google’s newest image model—Gemini Nano Banana Pro—has been making waves, and after spending a full week testing it intensively, I can confidently say one thing: this model understands realism better than anything Google has released so far.
Most AI tools over-polish images.
They chase unattainable beauty—perfect skin, smooth lighting, flawless symmetry.
But real people aren’t perfect.
They have:
- Uneven skin tone
- Tired eyes
- Natural lines and textures
- Stray hair
- Pores
- Sweat
- Scars and imperfections
And unlike many AI systems, Gemini Nano Banana Pro embraces these details instead of erasing them—making portraits look deeply human, raw, and documentary-like.
The 20 prompts below are built specifically to maximize realism, emotion, and natural lighting. Every prompt includes environmental, camera, and mood details—because small things like lens type and light direction dramatically affect the final output.
