Tips & best practices

  • Include subject, action, lighting, and camera angle for more predictable compositions.
  • Use premium quality when you need crisp details for e-commerce or ads; fast rendering for quick ideation and drafts.
  • Specify aspect ratio (16:9, 3:4, square) to avoid unexpected cropping in thumbnails or paid placements.
  • Add a short negative cue (e.g., "no text, no watermark, clean background") to keep outputs promo-ready.
