Seven Core Capabilities of Nano Banana 3
To use Nano Banana 3 (nanobanana3) efficiently, it helps to build a capability map first: what it does best, which scenarios it fits, and how to write prompts that stay stable. This nanobanana tutorial summarizes 7 core capabilities, each with a reusable nanobanana prompt template—and a one-click nanobanana entry at the end.
Capability 1: Fast text-to-image with clear constraints
Template:
[subject], in [scene], style [realistic/illustration/3D], lighting [soft/rim], camera [50mm/top-down], palette [warm/cool], materials [glass/metal/fabric], ratio [1:1/16:9/9:16], 4K
Capability 2: Image-to-image editing (keep structure, change parts)
Best pattern:
Keep [what must stay] unchanged; only change [what should change]; match lighting direction; do not alter [forbidden changes].
Capability 3: Style control (explore directions quickly)
Run 5 style branches first (minimal, lifestyle, poster, film, cyber), then refine.
Capability 4: Detail + materials + lighting coherence
Name materials, surface finish (matte/glossy/brushed), and key light explicitly.
Capability 5: Consistency across a set
Template:
same character/product, keep facial/features consistent, same outfit, same lighting direction, neutral background, generate headshot/half/full.
Capability 6: Visual explanations (teaching & training)
Template:
Visualize [concept] as [analogy], label 3 key points, flat illustration, white background, 16:9.
Capability 7: Scenario outputs (marketing, e-commerce, content)
- E-commerce: hero image, lifestyle image, benefit card
- Marketing: cover, poster, KV
- Education: diagrams, flashcards, chapter visuals
Quick mapping table
| Goal | What to emphasize | Typical keywords |
|---|---|---|
| More realistic | materials + lighting | realistic, studio light, shadow |
| More consistent | invariants | keep consistent, same character |
| Cleaner | composition + whitespace | clean background, centered |
| More premium | palette + texture | minimal, luxury, black & gold |
