A headshot is a specific type of portrait that focuses on the subject's face and shoulders. It's typically used for professional or business purposes and is designed to capture a person's personality and professionalism. A portrait, on the other hand, is a more general term that can include any type of photograph that captures a person's likeness. Portraits can be full-body shots, candid shots, or posed shots, and can be used for a variety of purposes including personal use, art, or documentation.
