Image Prompt Structure

Effective image prompts follow this structure:

Subject + Style + Details + Technical specs

Example: "A cozy coffee shop interior, warm golden lighting, rain visible through large windows, watercolor painting style, soft muted colors, wide angle composition"

The more specific you are about visual details, the better the result. Unlike text prompts, image prompts benefit from adjective-heavy descriptions.

Key Parameters to Control

Style: photorealistic, watercolor, oil painting, digital art, anime, pencil sketch, 3D render
Lighting: golden hour, dramatic shadows, soft diffused, neon, backlit, studio lighting

Composition: close-up, wide angle, bird's eye view, symmetrical, rule of thirds

Mood: serene, dramatic, whimsical, dark, vibrant, minimalist

Color palette: warm tones, cool blues, monochromatic, pastel, high contrast

Practice This

Generate the same scene in 5 different styles using ChatGPT (DALL-E) or your preferred image tool. Example: "a mountain landscape at sunset" in photorealistic, watercolor, anime, minimalist, and oil painting styles.

Try this on ChatGPT, Claude, or Gemini

Key Takeaways
  • Image prompts: Subject + Style + Details + Technical specs
  • Be adjective-heavy — visual detail matters more than brevity
  • Style, lighting, composition, and mood are the key parameters
  • Iterate and refine — image generation often takes multiple attempts
