Mid Shot

Mid Shot

The mid shot shows some part of the subject in more detail, whilst still showing enough for the audience to feel as if they were looking at the whole subject. In fact, this is an approximation of how you would see a person "in the flesh" if you were having a casual conversation. You wouldn't be paying any attention to their lower body, so that part of the picture is unnecessary. I think the mid shot was used here to help create the scene as a more real life situatuion and make the audience feel more involoved as if they are really there at the time.
