🧠 Best Practices for Prompting
Nano Banana is powerful, but how you prompt matters.
Think single edit, not kitchen sink. Precise, small steps work better than long multi-edit prompts.
Leverage world knowledge. The model knows context (e.g., where to place objects in real-world photos).
Iterate like a designer. Don’t expect perfection in one shot — refine step by step.
Use annotation tools. Scribble, highlight, or draw arrows → the model interprets visual intent.
Let it generate slogans. It can create surprisingly effective ad copy directly in the image.
👉 Pro tip: Treat it like a junior designer who’s super fast — but needs clear instructions.
