Mastering Nano Banana Prompts

Prompt engineering is the key to unlocking Nano Banana's full potential. Unlike other AI models, Nano Banana requires precise, specific prompts to achieve the best results while maintaining image integrity.

This advanced tutorial covers sophisticated prompting techniques that will help you achieve consistent, high-quality results every time.

Advanced Prompting Principles

1. Specificity is Key

Nano Banana performs best with highly specific instructions. The more precise your prompt, the better the results.

Good:

Transform the sunny beach background to a snowy mountain scene while keeping the people in the foreground exactly as they are, maintaining the same lighting direction and intensity

Avoid:

Change the background

2. Preservation Instructions

Always specify what should remain unchanged to maintain image coherence and quality.

Example:

Replace "Old Company" with "New Company" while keeping the logo, background, font style, and all other elements exactly the same

3. Context Awareness

Consider the overall context and style of your image when crafting prompts.

Example:

Add a vintage car to the scene while maintaining the same artistic style, color palette, and lighting conditions as the original image

Prompt Templates for Common Tasks

Text Replacement Template

Replace "[EXACT_ORIGINAL_TEXT]" with "[NEW_TEXT]" while keeping [SPECIFIC_ELEMENTS_TO_PRESERVE] exactly the same

Scene Transformation Template

Transform [SPECIFIC_AREA] from [CURRENT_STATE] to [DESIRED_STATE] while preserving [SUBJECTS/ELEMENTS] and maintaining [STYLE/LIGHTING/CONTEXT]

Object Addition Template

Add [OBJECT_DESCRIPTION] to [SPECIFIC_LOCATION] while maintaining the same [ARTISTIC_STYLE/COLOR_PALETTE/LIGHTING] as the original image

Advanced Techniques

Multi-Step Instructions

For complex edits, break down your prompt into clear, sequential steps.

Example:

First, replace "March 2024" with "March 2025". Then, change the background from office to modern co-working space. Finally, ensure the person remains in the same position with consistent lighting.

Style Consistency

Maintain artistic consistency by referencing the original image's style elements.

Example:

Replace the product name while maintaining the same vintage poster style, color scheme, and typography as the original design

Common Mistakes to Avoid

Vague Instructions

Problem: "Make it look better" or "Change the background"

Solution: Be specific about what to change and how

Ignoring Context

Problem: Not considering the overall image style and context

Solution: Always specify style preservation requirements

Over-complicating

Problem: Trying to change too many things at once

Solution: Break complex edits into smaller, focused steps
