Nano Banana Pro Prompting Strategy for Stable Output
This is a comprehensive set of 10 instructions and strategies for writing effective prompts for Nano Banana Pro (Gemini 3 Pro Image), aimed at stabilizing output and avoiding garbled text. It emphasizes switching to 'Thought Mode' or 'Pro Mode', using descriptive sentences instead of keyword lists, specifying subject/background/atmosphere, and using positive language and English keywords for quality.
① Always switch the mode to 'Thought' or 'Pro' (I feel 'Thought' is better) ② 'Describe the scene in sentences' rather than listing keywords ③ Specify the subject, background, and atmosphere as a set of three points ④ Don't aim for perfection in one go; apply 'gradual corrections' ⑤ Avoid negative expressions; give instructions in positive sentences ⑥ Add quality keywords (4K, high resolution) in English ⑦ Clearly state the purpose at the beginning (e.g., "{argument name="purpose" default="Diagram for a proposal"}") ⑧ Exclude unnecessary elements using negative prompts ⑨ Do not attempt complex edits all at once; proceed in segments ⑩ Save frequently used prompts as templates
