Prompt Architecture & Anatomy

🎭 Portrait Anatomy & Optical Breakdown



  • Subject: Primary human subject with natural facial features

  • Pose: Candid posture with relaxed, organic body language

  • Framing: Medium close-up portrait framing with head and shoulders focus

  • Camera Angle: Eye-level direct angle for authentic human engagement

  • Focal Intent: Optical 100mm optical lens portrait rendering with natural facial compression and no wide-angle distortion

  • Lighting: Soft diffused directional key light with gentle fill shadow transition

  • Skin Rendering: Subtle subsurface scattering, authentic micro-textures, natural pores without plastic airbrushing

  • Background Separation: Shallow depth of field (f/8) creating smooth creamy bokeh separation from background elements

  • Identity Constraints: Symmetrical anatomical proportions, sharp catchlights in eyes, clean jawline definition
