Best Practices for Nano Banana Prompting

Effective prompting is key to getting the best results from Nano Banana. Focus on descriptive, narrative-style prompts rather than keyword lists the model understands natural language like a conversation.

Be Descriptive and Specific: Include details on subjects, actions, environments, lighting, moods, and camera angles. Avoid vague terms like "nice image"— opt for "serene and masterful mood with golden hour lighting.

Use Scenario-Specific Details: Tailor prompts to the output type (e.g., photorealistic, stylized, or minimalist).

Iterate and Refine: Start broad, then refine with follow-up prompts like "Make it more data-dense."

Incorporate Constraints: Specify aspect ratios, platforms (e.g., mobile), or styles (e.g., Material Design) for targeted results.

High-Quality Inputs: Use high-resolution source images to avoid blurry outputs.

Short Text for Rendering: Keep added text under 25 characters for clarity.

Common pitfalls to avoid: Overly generic prompts lead to mediocre results; always test variations.
