Throughout this essay I am going to discuss the principles and purposes of editing.
Collage:
"A collection of images placed into one sequence".
When you place images together your audience interprets them and trys to understand the meaning of the images that they are seeing on the screen , they do this by taking in information that they see in the various different shots.
One image must be relevant to another e.g. one reveals information about the other allowing the viewer to understand what is going on further. Here is an an example of a collage
Tempo
Tempo can be used to set the pace of a scene for example if you are filming an action scene in a movie with speeding cars , you want the editing style to be fast paced.
You can achieve this fast paced feel by editing in the correct way the best technique is to make each clip very short so that the camera moves to many different angles. Or alternatively if you were filming a scene with a lot of dialogue then you might consider slowing down the pace of the film by keeping the camera in one place and allowing each shot to be longer.
Condensing and Expanding Time
The condensing and expanding of time is used in many different ways in film.
It can be used to create montages which are
supposed to make the viewer think that more
time has passed than it actually has.
It can be used to get rid of unnecessary footage and to
keep the film moving along at a steady pace.
Arranging the Order of Events
Different producers organize the sequence that events are shown in differently.
This can be used to add in things like flashbacks , visions , dreams , cutaways and things of that nature in which the viewer is shown a clip that does not seem to flow with the sequence of events.
Shot/Reverse Shot
A shot reverse shot is basically a cause and effect type setup for example two people will be having a conversation and the camera will be focused on the face of the person talking , when the other person responds to what they have said the camera changes to them..
Eyeline Match
An eyeline match is used to show us how a character in the movie sees the events going on around them for example their might be a pen that falls on the floors on screen and the next shot is the pen on the floor from the perspective of a character.
Cutaways
Cutaways are used to give the viewer some additional information relevant to the story line or plot of a film , a prime example of a cutaway can be see in the comedy television series family guy where the main protagonist "Peter Griffin" constantly has hilarious cutaways.
