The six-part formula

Subject + Action + Environment + Art style / lens + Lighting + Details

  • Subject. Who or what. Be specific about age, features and material.
  • Action. What is happening. Pose, motion, camera angle.
  • Environment. Location, backdrop, context.
  • Art style or lens. Camera, lens, film or medium, aesthetic.
  • Lighting. Direction, quality, time of day.
  • Details. The micro-elements that sell realism. Textures, shadows, reflections.

Pro tips

  • Specific beats vague. "Dramatic window lighting creating rim light" outperforms "nice lighting" every time.
  • Match specs to genre. A portrait is not a product shot, and neither is architecture.
  • Use real lenses and cameras. An 85mm, a Canon 5D Mk IV or medium-format film grounds the look.
  • Add plausibility cues. Fabric drape, pore texture, contact shadows and reflections do the heavy lifting.
  • For edits, say what to preserve. State what changes and what stays, such as "maintain realistic pores".
  • Time and weather reshape mood. Golden hour, soft afternoon and morning mist are different pictures.
  • Composition anchors help consistency. A foreground rock, rule of thirds, shallow depth of field.
