Portrait photography or portraiture is the capture by means of photography of the likeness of a person or a small group of people (a group portrait), in which the face and expression is predominant. The objective is to display the likeness, personality, and even the mood of the subject. Like other types of portraiture, the focus of the photograph is the person's face, although the entire body and the background may be included.                                                                                                                                                                               http://en.wikipedia.org/wiki/Portrait_photography              _
