The parts of a strong image prompt

  • Subject: who or what is in the picture, and what they are doing.
  • Style: photo, watercolor, anime, 3D render and so on.
  • Setting: the place or background.
  • Lighting: one of the biggest changes you can make to a picture.
  • Camera view: close-up, wide shot or bird's-eye view.
  • Mood and colors: how the image should feel.

Example

"A fox in a library" gives a random result. With this tool it becomes a watercolor painting of a red fox curled up asleep on a stack of old books in a quiet library, with soft natural light, a medium shot, a cozy mood and a warm palette, plus a negative prompt that keeps out blur, text and cropping.

Tips for better AI images

  • Put the most important thing first. Most tools pay more attention to the start of a prompt.
  • Change one setting at a time so you can see what each choice does.
  • Use the aspect ratio for the place you will post it, such as 9:16 for stories or 16:9 for YouTube.
  • Respect other people's work. Avoid copying living artists, real people or brand logos.

Frequently asked questions

Which image tools can I use these prompts with?

Most AI image tools that take a text prompt, including ChatGPT image generation, Gemini, Midjourney, Leonardo, Ideogram and Stable Diffusion tools. Choose the Midjourney format if you use Midjourney.

What is a negative prompt?

A negative prompt lists what you don't want in the image, such as blurry details, extra fingers or watermarks. Some tools have a separate box for it. In Midjourney, it goes after --no.

Does this tool create the image?

Why do my AI images look generic?

Short prompts leave most choices to the AI. Adding a style, lighting, camera view and color palette gives you much more control over the result.
