Generate a corporate LinkedIn portrait, three-quarter shot (¾ view, showing from head down to mid-thigh/waist area), based on the uploaded reference photo. The person must look straight into the camera, keeping the same facial features, bone structure, skin tone, hair, and natural expression as in the original photo. Respect the original pose. The subject is wearing a formal black dress shirt. The style must be ultra-realistic, ultra high-definition, photographed with Hasselblad H6D-400c quality, with soft natural lighting. Background: blurred modern office, professional depth of field. The image should look authentic, professional, and slightly enhanced for LinkedIn (balanced light, sharp details), but must fully preserve the person’s identity.
