How to Use AI Prompts for Better Images

Great AI art starts with a great prompt. Here is a simple formula that works every time:

  1. Start with the subject — What is the main focus? A person, a place, an object?
  2. Add the art style — Photorealistic, oil painting, anime, cyberpunk? This sets the visual language.
  3. Describe the lighting — Golden hour, neon glow, candlelight? Lighting is half the mood.
  4. Set the mood — Peaceful, dramatic, mysterious? This guides color and composition choices.
  5. Pick a camera angle — Wide angle for landscapes, 85mm for portraits, macro for details.
  6. Add quality modifiers — Terms like "highly detailed," "8K," and "sharp focus" push the AI toward higher fidelity.
