1. Prompt Engineering Fundamentals

What is Prompt Engineering?

Prompt engineering is the art and science of crafting text instructions that guide AI models to generate desired outputs. In image generation, a well-crafted prompt can mean the difference between a generic result and a masterpiece that perfectly captures your vision.

Core Principles

The 4 Pillars of Effective Prompts

1. Clarity

Be specific and unambiguous in your descriptions

2. Context

Provide relevant background and setting information

3. Composition

Structure your prompt logically and coherently

4. Constraints

Set boundaries and specify what you don’t want

2. Anatomy of a Perfect Prompt

A well-structured prompt follows a specific formula that maximizes the chances of getting your desired result. Here’s the anatomy of a perfect AI image prompt:

Prompt Structure Formula
[Subject] + [Action/Pose] + [Environment/Setting] + [Style] + [Technical Parameters] + [Negative Prompts]

Example Breakdown:

Subject: “A majestic golden retriever”
Action/Pose: “sitting gracefully, looking directly at camera”
Environment: “in a sunlit meadow with wildflowers”
Style: “professional pet photography, shallow depth of field”
Technical: “shot with 85mm lens, golden hour lighting, 4K resolution”
Negative: “--no blurry, dark, indoor, artificial lighting”

3. Advanced Techniques

Weight and Emphasis Control

Different AI models support various ways to emphasize certain elements in your prompt:

Parentheses Method (Stable Diffusion)

(beautiful landscape:1.3)

Increases weight by 30%

Bracket Method (Midjourney)

--stylize 750

Controls artistic interpretation

Repetition Method (Universal)

highly detailed, extremely detailed, ultra detailed

Emphasizes through repetition

Style Transfer Techniques

Learn how to incorporate specific artistic styles into your prompts:

Artist Style References
  • • “in the style of Van Gogh”
  • • “Monet impressionist painting”
  • • “Studio Ghibli animation style”
  • • “Greg Rutkowski digital art”
Technical Style Terms
  • • “photorealistic, hyperrealistic”
  • • “oil painting, watercolor”
  • • “3D render, octane render”
  • • “minimalist, abstract”

4. Model-Specific Strategies

Google Imagen 3

Imagen 3 excels at understanding natural language and context:

  • Use conversational, descriptive language
  • Focus on emotional context and atmosphere
  • Excellent at text rendering within images
  • Strong understanding of spatial relationships
Example: “A cozy coffee shop on a rainy evening, warm yellow light spilling onto wet cobblestones, with a handwritten ‘Open’ sign in the window, steam rising from a cup on the windowsill”
DALL-E 3

DALL-E 3 is excellent at following complex instructions:

  • Handles multi-object compositions well
  • Strong at text integration
  • Responds well to detailed scene descriptions
  • Good at maintaining consistency across elements
Example: “An infographic showing the water cycle, with clearly labeled arrows, modern flat design style, blue and green color scheme, educational poster format”
Midjourney

Midjourney excels at artistic and stylized outputs:

  • Use artistic terminology and style references
  • Leverage aspect ratio parameters (--ar 16:9)
  • Utilize chaos and stylize parameters
  • Strong at fantasy and surreal imagery
Example: “Epic fantasy landscape, floating islands connected by bridges, dramatic lighting, concept art style --ar 21:9 --stylize 750”

5. Practical Examples

Before & After: Prompt Optimization

❌ Poor Prompt
“cat sitting”

Issues: Too vague, no style guidance, no context, no technical specifications

✅ Optimized Prompt
“A fluffy orange tabby cat sitting elegantly on a vintage wooden windowsill, soft morning sunlight streaming through lace curtains, cozy cottage interior, professional pet photography, shallow depth of field, 85mm lens, warm color palette, highly detailed fur texture --no dark, blurry, artificial lighting”

Improvements: Specific subject, clear setting, style direction, technical parameters, negative prompts

Category-Specific Examples

Portrait Photography
“Professional headshot of a confident businesswoman, natural smile, modern office background, soft studio lighting, shot with 85mm lens, shallow depth of field, high resolution”
Product Photography
“Luxury watch on white marble surface, dramatic side lighting, reflections on metal, commercial product photography, clean minimalist composition, 4K resolution”
Landscape Art
“Misty mountain lake at sunrise, perfect reflections, pine trees silhouetted, golden hour lighting, serene atmosphere, landscape photography, wide angle view”
Digital Art
“Cyberpunk cityscape at night, neon lights, flying cars, rain-soaked streets, blade runner aesthetic, digital art, highly detailed, vibrant colors”

6. Common Issues & Solutions

Problem: Blurry or Low-Quality Results

Solutions:

  • Add quality keywords: “highly detailed”, “sharp focus”, “4K resolution”
  • Specify camera/lens details: “shot with 85mm lens”, “professional photography”
  • Use negative prompts: “--no blurry, low quality, pixelated”
Problem: Wrong Style or Mood

Solutions:

  • Be more specific about artistic style: “photorealistic” vs “cartoon style”
  • Add mood descriptors: “cheerful”, “melancholic”, “dramatic”
  • Reference specific artists or art movements
Problem: Unwanted Elements

Solutions:

  • Use negative prompts effectively: “--no people, text, watermarks”
  • Be more specific about what you want to avoid
  • Adjust prompt weighting to emphasize desired elements

7. Best Practices & Pro Tips

Essential Do’s and Don’ts

✅ DO

  • • Start with the most important elements
  • • Use specific, descriptive language
  • • Include technical photography terms
  • • Test variations of your prompts
  • • Save successful prompt formulas
  • • Use negative prompts strategically

❌ DON’T

  • • Use contradictory descriptions
  • • Make prompts unnecessarily long
  • • Rely on copyrighted character names
  • • Ignore model-specific syntax
  • • Forget to specify image quality
  • • Use vague or ambiguous terms

Advanced Pro Tips

1. Prompt Iteration Strategy

Start with a basic prompt, then gradually add details. This helps you understand which elements have the most impact on your results.

2. Style Mixing Technique

Combine multiple artistic styles for unique results: “oil painting meets digital art” or “vintage photography with modern color grading”.

3. Emotional Context

Include emotional descriptors to guide the AI’s interpretation: “joyful”, “mysterious”, “peaceful”, “energetic”. This often produces more compelling results.
