Ultra-realistic 8K corpor

Ultra-realistic 8K corporate headshot of the person in the input photo. Keep their exact face, identity, age, gender, ethnicity, hairstyle and expression; do not alter unique facial features. Replace clothing with a tailored navy blue wool business suit and crisp white shirt. Clean dark gray studio backdrop with a soft center-light gradient and subtle vignette, no objects. Style as a Sony A7III 85mm f/1.4 studio portrait in portrait orientation with shallow depth of field: subject sharp, background softly blurred. Soft three-point lighting with gentle shadows and a subtle rim light on hair and shoulders. Preserve natural skin texture with pores and fine details, no plastic smoothing. Bright, natural catchlights in the eyes. Final image: high-end LinkedIn-ready studio portrait.
