As AI image generation goes mainstream, writing efficient, precise prompts is what separates great outputs from random luck. Nanobanana Pro offers a universal prompt structure that works across almost every scenario — whether you are just starting out or want fine-grained control.
1. Core structure: clarity + detail + style
A strong prompt reads like a design brief. Use this universal formula:
Subject + Details + Style + Scene + Composition + Parameters
Four building blocks
| Element | What to specify |
|---|---|
| Clear subject | Who or what is the focus |
| Rich details | Appearance, materials, colors, pose |
| Defined style | Photoreal, cyberpunk, Ghibli, oil painting, etc. |
| Scene & framing | Environment, camera angle, shot size |
Tip: Lock subject and style first, then add lighting and micro-details — the model anchors the composition faster.
2. Art style: one line sets the mood
Pick a style early so the atmosphere forms quickly. Common choices on Nanobanana Pro:
- Photorealism — products, portraits, commercial visuals
- Cyberpunk — neon, futuristic cities, tech aesthetic
- Chinese traditional — ink wash, hanfu, classical architecture
- Ghibli-inspired — warm storytelling, hand-painted feel
- 3D render — Pixar-like, game assets, industrial design
- Impressionist / abstract / minimal — emotion and brand tone
Mix styles for a unique look, e.g. “Chinese traditional + cyberpunk lighting.”
3. Detail dimensions: light to texture
| Dimension | Examples |
|---|---|
| Color palette | Warm / cool / Morandi tones |
| Framing | Close-up / wide / bird’s-eye / low angle |
| Lighting | Bright / soft / dramatic / backlit |
| Texture | Fine / gritty / dreamy / film grain |
| Art movement | Impressionist / minimal / pop art |
Combo example:
Soft light + cool tones + bird’s-eye view + dreamy texture
Concrete phrases beat vague words like “beautiful” or “premium.”
4. Scenarios: one structure, many use cases
- Landscapes — mountains, ocean, forest, seasons
- Urban & architecture — streets, landmarks, interiors
- Daily life — food, home, portraits
- Commercial — posters, logos, product shots
- Anime & illustration — characters, panels, stickers
- Architecture — exteriors, interiors, aerials, sections
5. Advanced control: smarter prompts
5.1 Compact formula
Subject + Details + Style + Scene + Composition + Parameters = high-quality AI image
5.2 Parameters
- Sharpness, saturation, contrast — control clarity and color intensity
- Seed — reproducibility and small tweaks
- Multimodal input — image + text for character or product consistency
5.3 Prompt techniques
| Technique | Example |
|---|---|
| Weighting | (keyword:1.2) to emphasize elements |
| Style blend | “Ghibli style + cyberpunk lighting” |
| Negative constraints | List what to avoid |
5.4 Creative expansion
- Story: “A robot waiting in the rain”
- Mood: “lonely, quiet, dusk”
- Metaphor: “A shattered mirror reflecting the stars”
6. Full example prompt
Copy and adapt this template:
Subject: A Shiba Inu in an astronaut suit
Details: White helmet, clear visor, red button on chest
Style: 3D render + Pixar animation look
Scene: Martian surface, dust storm in the distance
Composition: Low-angle, close-up
Lighting: Sunset backlight, golden halo
Parameters: 8K, high detail, soft shadows
In Nanobanana Pro you can merge into one paragraph or keep line breaks for iteration.
