Close Up

Close up shots normally have just the face and shoulders of a subject, with a small amount of head room above. This prevents 'floating head syndrome' as the shoulders suggest to the brain that there is still a body. These shots are the most common of all as they can convey a strong sense of emotion and help the audience to connect with the character involved.  The background image behind the characters also adds to the atmosphere and is largely there to support the idea that the character is not just in an empty room and is still part of the scene despite the focus on them. Directors will use this shot to convey the character's emotion and to make the audience feel like they are a part of the scene, rather than just observers.
