Nano-Banana Workflow: Prompt + Banana for High-Efficiency Iteration
A reusable nanobananapro workflow: start with a master image, modularize prompts, iterate with single-variable edits, and scale to batch production while keeping consistency.

What this workflow solves
Most teams hit the same bottlenecks:
- First output is close, but details are off
- Edits drift identity (background/style changes break consistency)
- Batch production is slow (rewriting prompts from scratch)
The fix is not “more tries”—it’s a repeatable workflow.
The linkage: prompt × reference × edit instruction
Think in versions:
- Prompt defines the target (subject, scene, style, constraints)
- Reference image locks identity (face / product shape / brand traits)
- Edit instruction changes one variable at a time
This yields stable direction + controlled iteration.
Standard process
Step 1: Create a “master” image
Goal: accurate subject + strong composition + clean background.
Keep the first prompt simple and constraint-heavy.
Step 2: Turn it into a template
Split your prompt into:
- Fixed: identity traits / camera / lighting / constraints
- Variable: scene / style / props / whitespace
Step 3: Single-variable iteration
Avoid changing style + background + camera at once. Recommended order:
- change background (identity stays)
- change style (composition stays)
- change camera angle (lighting stays consistent)
Use “keep unchanged” phrasing:
Keep the face and hairstyle unchanged. Only replace the background with…
Step 4: Batch export + QC checklist
Before batch output, define a QC checklist:
- identity consistency (face / logo / product shape)
- cleanliness (no watermark / no unwanted text)
- sharpness (clean edges, no artifacts)
- whitespace for copy (if needed)
