How can Camera Angles and Signifiers Communicate?

There are different forms in which camera angles and signifiers can communicate. Signifiers are visual or oral signs that directors/authors use for the audience to place meanings to. Signifiers are used everywhere from our own lives to movies: when crossing a street, you look for the 'green man' to signify that it's safe; when trying on clothes you look at the label to see the size; when watching a movie and you hear thunder …

…Though signifiers can be miscalculated, they are usually quite easy to work out. Camera angles set an atmosphere, i.e. if it is an extreme long shot, it is most likely that the director wants the audience to be looking for something specific; this would set a suspenseful atmosphere. Camera angles and signifiers can be communicated in many forms, but in the end it is down to the audience to place a meaning to it.
