Nano Banana Prompt Engineering Guide

Mastering the art of prompt is crucial for generating high-quality images with AI tools. This comprehensive guide will teach you how to craft effective prompts that produce stunning results.

Understanding Prompt Structure

A well-structured prompt typically consists of several key components:

1. Subject Description

Clearly define what you want to generate:

  • Main subject: Person, animal, object, or scene
  • Physical attributes: Age, gender, appearance, clothing
  • Actions or poses: What the subject is doing

Example: "A young woman with curly red hair, wearing a blue dress, sitting on a park bench"

2. Environment and Setting

Describe the background and context:

  • Location: Indoor, outdoor, specific places
  • Time of day: Morning, sunset, night
  • Weather conditions: Sunny, rainy, foggy
  • Atmosphere: Peaceful, dramatic, mysterious

Example: "in a misty forest during golden hour, with sunbeams filtering through tall trees"

3. Style and Artistic Direction

Specify the visual style you want:

  • Art styles: Oil painting, watercolor, digital art, photography
  • Art movements: Impressionism, surrealism, minimalism
  • Technical aspects: Lighting, composition, color palette

Example: "painted in impressionist style with soft brushstrokes and warm colors"

Advanced Techniques

Negative Prompts

Use negative prompts to exclude unwanted elements:

  • "NOT blurry, NOT dark, NOT distorted"
  • "Avoid modern elements, no text, no watermarks"

Weight and Emphasis

Emphasize important elements:

  • Use parentheses: "(beautiful landscape)"
  • Add descriptive words: "extremely detailed", "highly realistic"

Technical Parameters

Specify technical requirements:

  • Resolution: "4K", "high resolution", "ultra detailed"
  • Aspect ratio: "16:9", "portrait orientation"
  • Quality: "masterpiece", "professional photography"

Common Mistakes to Avoid

  1. Overly complex prompts: Keep it focused and clear
  2. Contradictory instructions: Ensure all elements work together
  3. Vague descriptions: Be specific about what you want
  4. Ignoring composition: Consider how elements are arranged

Practice Examples

Portrait Photography

Professional headshot of a confident businessman in his 40s, 
wearing a navy blue suit and tie, sitting in a modern office, 
natural lighting from large windows, shot with 85mm lens, 
shallow depth of field, corporate photography style

Landscape Art

Serene mountain lake at sunrise, snow-capped peaks reflected 
in crystal clear water, pine trees in foreground, golden hour 
lighting, painted in romantic landscape style, oil on canvas, 
detailed brushwork, warm color palette

Fantasy Scene

Majestic dragon perched on ancient castle tower, breathing 
fire into stormy sky, medieval fantasy setting, dramatic 
lighting with lightning bolts, digital art style, highly 
detailed, epic composition, dark and moody atmosphere

Tips for Success

  • Start simple: Begin with basic prompts and gradually add complexity
  • Experiment: Try different combinations and styles
  • Study examples: Learn from successful prompts
  • Iterate: Refine your prompts based on results
  • Keep notes: Document what works for future reference

Next Steps

Once you've mastered basic prompt, explore:

  • Advanced style techniques
  • Composition and framing
  • Color theory applications
  • Specific genre conventions

Remember, prompt is both an art and a science. The more you practice, the better you'll become at creating prompts that generate exactly what you envision.
