Cinematic techniques
Cinematographic techniques such as the choice of shot, and camera movement, can greatly influence the structure and meaning of a film.
Size of shot
The use of different shot sizes can influence the meaning which an audience will interpret.
The size of the subject in frame depends on two things: the distance the camera is away from the subject and the focal length of the camera lens.
Common shot sizes:
* Extreme close-up: Focuses on a single facial feature, such as lips and eyes.
* Close-up: May be used to show tension.
* Medium shot: Often used, but considered bad practice by many directors, as it often denies setting establishment and is generally less effective than the Close-up.
* Long shot
* Establishing shot: Mainly used at a new location to give the audience a sense of locality.
Choice of shot size is also directly related to the size of the final display screen the audience will see. A Long shot has much more dramatic power on a large theater screen, whereas the same shot would be powerless on a small TV or computer screen.
