How to use Nano Banana: a practical workflow
1) Start with a clear goal
Nano Banana is best when you need fast, consistent edits. Define the goal before you prompt:
- “Keep the same model, change the background”
- “Generate a product lineup with the same lighting”
- “Create a set of travel posters with one style”
Clear intent reduces randomness and speeds up iteration.
2) Choose your reference images
One clean reference is often enough. Use more only when necessary.
Recommended approach
- Primary reference: the person/product you must preserve
- Secondary reference (optional): style, lighting, or environment
- Avoid overly filtered or blurry images
If you use multiple references, explain the role of each in your prompt (e.g., “use photo A for identity, photo B for lighting”).
3) Use a stable prompt structure
The most reliable structure is:
Subject + Scene + Style + Constraints
Example:
same person, studio lighting, teal accents, keep face and hairstyle, do not change outfit
Constraints like “keep face,” “preserve pose,” or “do not change logo” are critical for consistent output.
4) Set the right model & size
Nano Banana is the fastest model for consistent edits. Choose your resolution based on need:
- 1k for fast iteration
- 2k for product shots
- 4k for final production (often Nano Banana Pro)
If you need strong typography or 4K, consider Nano Banana Pro.
5) Generate in batches
Small batch generation helps you compare variations quickly:
- Generate 2–4 options
- Pick the best
- Re‑prompt only the chosen one
This keeps your iterations tight and avoids drifting too far from the goal.
6) Refine with short edits
After the first pass, use short, surgical edits:
- “Increase rim light”
- “Replace background with Tokyo street at night”
- “Make the product glossy and reflective”
Short prompts reduce unexpected changes.
7) Keep consistency across multiple outputs
If you need a series (e.g., 6 social posts), keep a consistent template:
- Fixed prompt structure
- Same reference images
- Same aspect ratio
- Same constraints
You can also note “use the same character as previous output” to guide follow‑ups.
8) Export and post‑process
Export PNG/JPG and finish in your design tools. For Photoshop workflows:
- Export PNG
- Add text, masks, or layers
- Re‑upload if you need another AI iteration
9) Common issues & quick fixes
Problem: face changes
Fix: add “keep face, preserve identity” and re‑upload a clean reference
Problem: layout drifts
Fix: add layout constraints like “center subject, top margin 15%”
Problem: text is inconsistent
Fix: switch to Nano Banana Pro and specify font style & placement
10) A simple checklist
- Clear goal
- Strong reference
- Short prompt + explicit constraints
- Generate small batches
- Refine only the best outputs
Final note
Nano Banana is an image model, not a video model. Focus on images and iterate quickly for the best results.
