Strict black and white portrait

Strictly maintain a 1:1 appearance — facial features, skin texture, hair color, and length. 3:4 aspect ratio. Black and white studio bust portrait. Camera strictly at eye level, no tilt. Pose: torso facing directly towards the camera, shoulders symmetrical. Head straight, no tilt or turn. Gaze strictly into the lens. Lips slightly closed, neutral expression. Hair down, center part, naturally falling on both sides of the face. Clothing: black blazer, with a white shirt with an unbuttoned collar underneath. Solid dark gray background. Lighting: soft but directional light from top-side (top-down diffused), with a light rim light along the hair contour to separate it from the background. Enhanced skin micro-contrast, clear texture detail, deep shadows and bright highlights without overexposure. Light film grain, crisp detail, cinematic editorial look, 85mm, f/2.8, Hasselblad.
