An extreme close up focuses on a specific facial feature or reaction to show emotion. For example, in Shrek 3 the camera zooms in on Shrek's face when he learns Fiona is pregnant to show his worry. A high angle shot is taken from above to depict characters as being in danger or having done something wrong. A low angle shot is taken from below to symbolize a loss of power. Close ups are used to show a character's emotions at a key moment so the audience understands how they feel.
