Module 6 Lesson 5: Visual Description for AI Art

Bridges the gap between words and images. How to use ChatGPT to generate high-quality prompts for Midjourney and DALL-E.

Visual Description for AI Art

Even if you aren't an artist, you can use ChatGPT to become a Visual Architect. Tools like Midjourney, DALL-E, and Stable Diffusion require highly descriptive prompts that mention lighting, camera angles, and textures.

1. The Visual Framework

A great art prompt often follows this sequence:

  1. Subject: What is in the image?
  2. Action/Setting: Where are they? What are they doing?
  3. Medium/Style: Oil painting? 3D Render? Cyberpunk?
  4. Lighting: Cinematic, soft, neon, golden hour.
  5. Camera: Wide shot, macro, 35mm lens.

2. Using ChatGPT as a "Prompt Expander"

You give a simple idea; the AI gives the technical details.

Example Prompt:

"I want to generate an image of a 'Cyberpunk City'. Expand this into a detailed prompt for Midjourney. Include specifics about neon lighting, rain on concrete, reflective surfaces, and a 8k cinematic feel. Suggest a specific artist style to emulate."

3. Consistent Characters

Use the AI to describe the same character in different scenarios.

  • "Describe a knight named Sir Cedric. Now, describe Sir Cedric eating a sandwich in a tavern. Now, describe Sir Cedric fighting a dragon. Keep the facial features and armor descriptions consistent in every prompt."

4. UI/UX Mockups

Designers use AI for inspiration.

  • "Describe a mobile app interface for a high-end watch store. Focus on a dark mode aesthetic, glassmorphism elements, and premium typography."

Hands-on: The "Reverse Image" Prompt

  1. Look at a famous painting (e.g., "The Starry Night").
  2. Ask ChatGPT: "Describe 'The Starry Night' in such detail that an AI image generator could recreate its spirit. Don't use the name of the painting or the artist. Focus on the brushstrokes, the colors, and the emotional energy."

Key Takeaways

  • Mention Lighting and Camera Angles.
  • Use Prompt Expansion for technical depth.
  • Consistency is key for storytelling.
