Generate a corporate LinkedIn portrait, three-quarter shot (showing from head down to mid-thigh/waist), based on the uploaded reference photo. The person must look straight into the camera, keeping the same facial features, bone structure, skin tone, brown eyes, hair, and natural expression as in the original photo. Respect the original pose. The subject is wearing a formal black dress shirt. Ultra-realistic, ultra high-definition, Hasselblad H6D-400c lens style, natural soft lighting. Background: blurred modern office, professional depth of field. The photo should look authentic, professional, and slightly enhanced for LinkedIn (balanced light, sharp details), while fully preserving the person’s identity and recognizability. Vertical format, aspect ratio 2:3 to allow cropping for LinkedIn and corporate use.
