Writing prompts for image generators is fundamentally different from writing prompts for text AI. While text prompts are conversational, image prompts are more like descriptive blueprints — every word shapes the visual output.

How Image AI Interprets Prompts

Image generators process your text through a model called CLIP (or similar) that maps words to visual concepts. Understanding this helps you write better prompts:

• Word order matters — Earlier words in your prompt often carry more weight. Lead with the most important elements.
• Specificity beats vagueness — "A golden retriever puppy sitting in autumn leaves" produces far better results than "a dog outside."
• Style descriptors are powerful — Terms like "cinematic lighting," "oil painting," or "35mm film photography" dramatically change the output.
• Avoid negation in positive prompts — Saying "no trees" doesn't work well. Use negative prompts instead (covered in Lesson 4).

The Anatomy of a Great Image Prompt

A strong prompt typically includes these components:

1. Subject — What is the main focus? ("A cyberpunk samurai")
2. Action/Pose — What are they doing? ("standing on a rooftop")
3. Environment — Where is the scene set? ("neon-lit Tokyo skyline at night")
4. Style — What artistic approach? ("digital art, cinematic, highly detailed")
5. Technical details — Camera, lighting, composition? ("wide-angle lens, dramatic backlighting")

Example Progression

Basic: "A castle" Better: "A medieval castle on a cliff overlooking the ocean" Best: "A weathered medieval castle perched on dramatic sea cliffs, stormy ocean below, golden hour lighting breaking through dark clouds, cinematic composition, photorealistic, 4K detail"

Platform Differences

• Midjourney — Excels at artistic, stylized images. Responds well to aesthetic descriptors and artist references.
• DALL-E 3 — Best at following complex instructions precisely. Handles text in images well.
• Stable Diffusion — Most customizable with models, LoRAs, and ControlNet. Requires more technical prompting.
• Flux — Fast, high-quality generation with strong prompt adherence and natural language understanding.

The best image prompt engineers think visually. Before writing, close your eyes and picture exactly what you want to see.
