Turn the attached photo into a professional headshot of the Subject. Keep the person exactly as they appear in the photo, preserving their face, facial features, skin tone, hair, facial hair and body type without retouching that changes who they are. If no photo is attached, use the Subject described below.
Frame the subject from the chest up, facing the camera with a calm, natural expression. Use subtle window light from one side, with gentle shadow shaping across the face and soft falloff on the opposite side. Keep the eyes sharp and the background softly out of focus, using the Background. Style the portrait with the Mood, restrained contrast and natural skin texture. Use an 85mm portrait lens perspective, a clean professional composition and the Format. Avoid exaggerated retouching, artificial facial changes and distracting background details.
Use these details:
Subject: "a man in his early 30s with short dark hair and a neatly trimmed beard"
Background: "a softly blurred charcoal-gray studio wall"
Mood: "moody, professional and approachable"
Format: "4:5 vertical portrait"
