How the prompt generator works

1
DescribeWrite a brief concept like "woman making salad in sunny kitchen"
2
Scene typePeople, environment, product, or let AI auto-detect
3
Get promptAI generates a 250-500 word NB2 prompt with camera, lighting, and materials

This Nano Banana prompt generator uses the same 13 production rules behind expert Nano Banana Pro prompts. Real camera gear forces optical emulation, per-material light interaction adds the realism multiplier, muscle-based expressions replace stock-photo grins, and 8+ texture anchors prevent the plastic AI look. Think of it as a Nano Banana prompt guide, prompt library, and AI image prompt generator in one. Works for NB2 headshots, portraits, product shots, and environments.

Why use a Nano Banana prompt generator?

Nano Banana Pro prompts. Photorealistic results.

Expert camera setup
Real camera body + lens + aperture forces optical emulation. Sony A7R IV, Canon RF 50mm, specific f-stops that NB2 understands.
Material light interaction
Per-surface light behavior: skin subsurface scattering, fabric diffuse, metal specular, wood grain. The realism multiplier that most prompts miss.
Anti-AI smoothing
Muscle-based expressions, texture anchors, visible pores. Strips "smooth," "flawless," "perfect" — the words that trigger plastic AI faces.
Frequently asked questions

Common questions

What is Nano Banana 2 and Nano Banana Pro?
Nano Banana 2 (NB2) and Nano Banana Pro are photorealistic AI image generation models available on kie.ai (Higgsfield) and through Google's Gemini. Nano Banana Pro offers maximum quality with deeper reasoning, while NB2 is faster and cheaper at 95% of Pro's quality. Both excel at generating realistic images when given detailed, structured prompts with camera specifications, lighting setups, and material descriptions. This Nano Banana prompt generator works for both models.
How do I write a good Nano Banana prompt?
A good Nano Banana prompt needs 5 elements: a style/mood opener, specific subject details, real camera gear (Sony A7R IV, 85mm f/1.8), directional lighting with color temperature, and per-material light interaction. Skip vague words like "beautiful" or "stunning" — use texture language instead. This Nano Banana prompt guide is built into the generator: describe your concept in 5-30 words and the AI expands it into a 250-500 word production-ready prompt following all 13 rules.
What makes these Nano Banana prompts better than writing my own?
These Nano Banana Pro prompts follow 13 hard rules proven in production: real camera gear forcing optical emulation, per-material light interaction breakdowns (the realism multiplier most prompts miss), muscle-based facial expressions instead of emotion words, 8+ texture anchors, subsurface scattering at thin skin areas, and anti-beautification constraints. This is expert-level prompt engineering that takes hours to learn — the generator does it in seconds.
Is this Nano Banana prompt generator free?
Yes. You get 5 free Nano Banana prompts with no account and no credit card. After that, create a free account for 3 prompts per day. For unlimited Nano Banana Pro prompt generation, buy credits starting at $4.99. Every prompt includes camera gear, lighting, material interaction, and anti-AI smoothing — the same quality whether free or paid.
Can I use these prompts for Nano Banana headshots and portraits?
Absolutely. Select "People" as the scene type and describe your portrait concept. The generator creates Nano Banana headshot prompts and portrait prompts with muscle-based expressions (not stock-photo grins), partial visibility framing, subsurface scattering, and anti-smoothing constraints. The result looks like a real photograph, not an AI render.
Can I edit the generated prompt?
Yes — copy the Nano Banana prompt and modify any section. If an image fails, simplify the POSE AND HANDS section first (most common failure source), then reduce scene density, change camera angle, or drop to a single light source. Never regenerate the exact same prompt. The prompt examples this tool generates are starting points you can customize.
What aspect ratio should I use?
Aspect ratio is set in the Higgsfield / kie.ai UI dropdown, not in the Nano Banana prompt text. The generated prompt intentionally excludes aspect ratio so you can choose freely. Common choices: 3:4 for portraits, 16:9 for landscapes, 1:1 for product shots, 4:5 for stock photography.
Does this work as a Gemini Nano Banana prompt generator?
Yes. Since Nano Banana 2 is powered by Google's Gemini architecture, the prompts this generator creates work across all Nano Banana implementations — kie.ai, Higgsfield, and Gemini's native image generation. The structured format with camera gear, lighting, and material descriptions optimizes for the underlying model regardless of which platform you use.
