CINEMATOGRAPHY
Cinematography is the act of capturing photographic images in space through the use of a number of controllable elements. These include the quality of the film stock, the manipulation of the camera lens, framing, scale and movement. Some theoreticians and film historians (Bordwell, Thompson) would also include duration, or the length of the shot, but we discuss the long take in our editing page. Cinematography is a function of the relationship between the camera lens and a light source, the focal length of the lens, the camera’s position and its capacity for motion.

Deep Focus
Depth of field is the measure that can be applied to the area in focus within the frame.
Deep focus,
which requires a small aperture and lots of light, means that the
foreground, middleground and background of the frame remain in focus.
In the image below, from
Citizen Kane (Orson Welles, 1941),
the extended depth of field gives the frame a 3-dimensional quality,
showing multiple planes of action at once. It also allows the filmmaker
to demonstrate the largesse of Kane’s dinner party and his personality.
The ability to achieve deep focus was the result of a technological
development in the lens in the late 193os and its adoption as a
discursive mode is largely attributed to Welles.
Shallow Focus
Shallow focus
is a function of a narrow depth of field and it implies that only one
plane of the frame will remain sharp and clear (usually the foreground).
In contemporary cinema, shallow focus is often combined with deep
space for artistic purposes or to demonstrate subjectivity. It is
typically a feature of the close-up. The following images, from
Rossellini’s Rome Open City (1945) and Sofia Coppola’s Marie Antoinette (2006), respectively, are
demonstrative of shallow focus. Each signals to a pivotal moment in
the character’s life – Don Pietro awaits his execution and Marie
Antoinette approaches the alter at her wedding.

Racking Focus
Filmmakers can change the focus of the lens to a subject in the
background from the foreground or vice vera. This can be used to shift
the audience’s attention or to point out a significant relationship
between the two subjects. In this sequence from Wes Anderson’s
Rushmore (1998), racking focus is used to show the miserable relationship between Herman Blume and his wife.
