These prompts are pulled from the live catalog so you can remix proven ideas instead of starting from zero.

Tips for great prompts
  • Describe the style, not the subject — the uploaded photo already supplies the subject.
  • Add lighting, medium, camera, or era cues for more distinctive results.
  • Use negative prompts to reduce blur, artifacts, and unwanted accessories.
