CLOSE UP: This shot can show emotions and reactions of a character to a person or object or event. It can help see the entire facial response, but can also be used to show certain stimulus e.g. a door handle or a keyboard etc. 

EXTREME CLOSE UP: These shots are useful because they can show really intense moments or specific things that will later be involved in the plot e.g. a person's eyes looking frightened, a watch face, a phone screen etc. 

LOW ANGLE: Low angle shots can give a POV perspective of a building, or something taller than the camera, these angles can often give status or indicate something bad coming e.g. if the camera was looking up into a dark sky, or if it was the POV of a kid looking at a teacher it would show who's in charge.

HIGH ANGLE SHOT: These shots again, give a sense of perspective and status, but this time in the point of view of someone who is in charge or who is definitely not in charge. 

MID SHOT: A mid shot is more to do with the characters and their relationships
