Use the attached selfie as the reference for the person. Keep his identity exactly the same, including face, facial features, skin tone, hair, body type and natural proportions. Do not reshape his face or apply retouching that changes how he looks. If no photo is attached, use the Subject described below.
Turn the reference into a welcoming real estate headshot. Give him the Expression and place him in the Background, with a softly separated background created by shallow depth of field. Use flattering window light from the front and side, gentle shadow definition, natural skin texture and a clean, approachable professional tone. Frame him from the chest up at eye level, with relaxed shoulders and direct eye contact. Use a portrait lens look around 85mm, with crisp focus on the eyes and subtle background bokeh. Keep the composition uncluttered and suitable for a real estate agent profile, LinkedIn, website bio or property listing. Render the image in the Format.
Use these details:
Subject: "man with short dark hair and a friendly appearance"
Expression: "warm, approachable smile"
Background: "softly blurred office plant backdrop"
Format: "4:5 vertical portrait"
