What is an image prompt?

An image prompt is a text description that tells an AI image generator what to create. It usually includes:

  • Subject (what is in the image)
  • Style (e.g. cinematic, watercolor, 3D, cyberpunk)
  • Lighting (soft daylight, neon rim light, studio softbox)
  • Composition (close-up, wide shot, bird’s-eye view, centered)
  • Details and constraints (camera lens, aspect ratio, mood, background)

Why prompts matter

AI models are sensitive to wording. Small changes can strongly affect:

  • Color palette and atmosphere
  • The “camera” look (lens, depth of field)
  • Level of realism vs illustration
  • Consistency across multiple generations

A simple prompt template

Use this as a reliable starting point:

  1. Subject: who/what is the main focus?
  2. Scene: where is it, what is happening?
  3. Style: art movement, medium, visual reference
  4. Lighting: time of day, key light, mood
  5. Camera: focal length, depth of field, shot type
  6. Quality: sharp, detailed, clean, cinematic, etc.

Example:

portrait of a traveler in a rainy neon city, cyberpunk style, cinematic lighting, shallow depth of field, 85mm lens, ultra detailed, high contrast
