Mastering the prompt: Pro tips for Nano Banana 2

To get the best results from Nano Banana 2.0, use these prompting strategies to leverage its Gemini 3.1 Flash architecture:

• Be specific and detailed: Include clear descriptions of your subject, specifying who or what should appear in the image. Add details about style, mood, and lighting to shape the overall look and feel. Mention composition elements, such as perspective or layout, to help the AI generate more accurate and visually appealing results.
• Be specific with text rendering and placement: Enclose exact text in double quotes, specify font style, position, and integration (e.g., "floating holographic text 'Future Tech 2026' in sleek sans-serif font above the robot"). Add localization or multilingual needs directly: "Localize all text to Spanish with vibrant Mexican cultural elements."
• Incorporate camera/lighting details for control: Include realistic photography terms like lens (35mm, 85mm), aperture (f/1.8 for bokeh), angle (low-angle dramatic shot), or lighting (volumetric god rays, soft diffused morning light). This guides spatial logic, depth, and mood precisely — especially useful for avoiding misplaced objects in busy scenes.
• Leverage real-time grounding for factual accuracy: For real-world subjects (landmarks, events, products), phrase prompts to activate search knowledge: "Create a realistic image of the current Eiffel Tower at night during the 2026 Olympics, accurate lighting and flags based on latest details." This grounds outputs up-to-date info for infographics, diagrams, or contextual visuals.
