Prompt Engineering Concepts

The practice of crafting effective text prompts to guide AI image generation. Involves understanding how models interpret text and using techniques to achieve desired results.

Prompt engineering is the skill of communicating your vision to AI image generators effectively.

Core Formula

A well-structured prompt typically includes:

[Subject] + [Style] + [Medium] + [Lighting] + [Composition] + [Quality]

Key Techniques

Be Specific

  • Weak: “a dog”
  • Strong: “a golden retriever puppy with fluffy fur”

Order Matters

Models often weight earlier terms more heavily. Put important elements first.

Use Quality Boosters

Common enhancers:

  • “highly detailed”
  • “8k resolution”
  • “masterpiece”
  • “professional”
  • “award-winning”

Style References

  • Artist names (use ethically)
  • Art movements: “impressionist”, “art deco”
  • Media: “oil painting”, “digital art”

Negative Prompts

Specify what to avoid:

  • “blurry, low quality”
  • “bad anatomy, extra limbs”
  • “watermark, signature”

Advanced Techniques

Token Weighting

Emphasize or de-emphasize terms:

  • (important word:1.3)
  • (less important:0.7)

BREAK Keyword

Separate concepts into chunks (SD):

Prompt Templates

Build reusable structures for consistent styles.
