Point of View Shots and Over the Shoulder Shot

Point of View Shot: (also known as POV shot or a subjective camera) This type of shot is used to show a view from the subject's perspective. Usually established by being positioned between a shot of a character looking at something, and a shot showing the character's reaction so the audience is aware that it is a POV shot.
Over the Shoulder Shot: This type of shot is taken from behind a person at the subject, cutting off the frame just behind the ear. The person facing the subject should occupy about 1/3 of the frame.This shot helps to establish the positions of each person, and get the feel of looking at one person from the other's point of view.

Point of View Picture

This point of view shot took place just after an establishing shot of a character "Locke" looking at the television at the video being played, which tells the audience that this is what john is currently watching. This allows the director to have the audience more engaged at what is being shown/ what the character is looking at.

Over the Shoulder Picture

This shot was used to connect the audience to the characters and the events going on around/between the characters. This shot, I felt, was used to great effect as it also showed the expressions on the characters face which may have been lost it it was taken from a medium shot.
