A practical prompt guide

Build clear prompts for image generation and editing. Start with the subject, then describe the visual choices that matter.

1) Text-to-image prompts

Subject + action + setting + style + composition + light + details + constraints

Realistic photography

A woman in a pale coat on a rainy street at night. Neon reflections, a medium photographic frame, soft background blur and cool light. Preserve natural skin texture; omit lettering.

Illustration and style

An orange cat with swimming goggles beside an aquarium. Use flat illustration, tidy outlines, a light palette and generous negative space.

Composition and focus

3) Best practices

  • Start with a short description and refine one detail at a time.
  • Specify camera, material and lighting instead of vague quality words.
  • State what to preserve before requesting an edit.
  • Avoid contradictory instructions and reuse character descriptions for consistency.
