Prompt Architecture & Anatomy
🎭 Portrait Anatomy & Optical Breakdown
- Subject: Primary human subject with natural facial features
- Pose: Natural relaxed posture facing the lens
- 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
