🏗️ Nano Banana Pro Prompts - Core Prompting Framework

Unlike older models that relied on "keyword soup," Nano Banana Pro thrives on structured, descriptive natural language.

The "Perfect Prompt" Formula

> [Subject + Adjectives] doing [Action] in [Location/Context]. [Composition/Camera Angle]. [Lighting/Atmosphere]. [Style/Media]. [Specific Constraint/Text].

• Subject: "A translucent glass robot barista..."
• Action: "...pouring latte art..."
• Location: "...inside a cozy, cyberpunk coffee shop..."
• Composition: "...Macro close-up shot, shallow depth of field (f/1.8)..."
• Lighting: "...illuminated by neon pink and teal signage reflection..."
• Style: "...Cinematic 8k render, Octane render style."
• Constraint: "The robot's chest display reads 'WAKE UP' in bold LCD font."

Refining the Details: Camera & Constraints

To elevate your prompts from basic to professional, you need to move beyond general descriptions and incorporate precise technical specifications. Mastering these elements gives you director-level control over the final output.

1. Camera & Lighting Control

• Stop guessing and start directing. Use cinematic terminology to define the exact look of your image.
• Don't say: "Good lighting."
• Do say: "A low-angle shot with shallow depth of field (f/1.8), golden hour backlighting creating long shadows." or "Soft diffused north-facing window light."

2. Precise Text Integration

• Nano Banana Pro excels at text, but it needs specific instructions on appearance and placement.
• Don't say: "Add text."
• Do say: "The headline 'URBAN EXPLORER' rendered in bold, white, sans-serif font at the top, centered on the sign."

3. Factual & Historical Constraints

• Leverage the model's grounding capabilities by demanding accuracy.
• Instruction: "A scientifically accurate cross-section diagram" or "Ensure historical accuracy for the Victorian era clothing and architecture."

🔑 Key Prompting Principles (The ICS Rule)

To consistently get what you want, structure Nano Banana Pro prompts around these three pillars:

1. Image Type: Is it a photo, a 3D render, a diagram, or a sketch?
2. Content: Who is the subject? What are they doing?
3. Style: What is the aesthetic (e.g., cyberpunk, watercolor, photorealistic)?
