Inputs to customise

  • subjectThe person, product, object, logo, or scene to generate.
  • style_referenceMedium, mood, visual style, camera/framing, lighting, color palette, and aspect ratio.
  • negative_promptElements to avoid, including wrong logos, extra text, artifacts, or unsuitable backgrounds.

Quality checks

  • Camera system is named with specific lens, ISO, and aperture — not generic 'professional camera'
  • Skin or organic surface texture explicitly requests natural pores and authentic highlights
  • Common AI realism failures (extra fingers, smoothed skin, shadow inconsistencies) are explicitly excluded
