Chapter 5: Cinematography Flashcards
(77 cards)
Cinematography
a general term for all the manipulations of the film strip by the camera in the shooting phase and by the laboratory in the developing phase
The Range of Tonalities
the control of the image’s range of tones and shades
tonality is a matter of considering how the light registers on the film
Contrast
refers to the comparative difference between the darkest and lightest areas of the frame
What is the function of contrast?
contrasts in the image help filmmakers to guide the viewer’s eye to important parts of the frame and to give the shot an emotionally expressive quality
High-Contrast
bright white highlights, stark black areas, and a narrow range of shades in between (stark and dramatic)
Low-Contrast
intermediate grays or color shades with no true white or black areas (muted emotional states)
What controls contrast?
lighting, filters, choice of film stock, laboratory processing, and post-production work
Exposure
regulates how much light passes through the camera lens
too dark = underexposed
too bright = overexposed
What is one key function of exposure?
it is a crucial way to alter the tonalities in the image
Filters
slices of glass or gelatin put in front of the lens of the camera or printer to reduce certain frequencies of light reaching the film
Tinting
accomplished by dipping the already-developed film into a bath of dye- the dark areas remain black and gray, while the lighter areas pick up the color
Toning
the dye is added during the development of the positive print- darker areas are colored, while lighter portions of the frame remain white or only faintly colored
What is the speed of motion dependent on?
- the rate at which the film was shot
- the rate of projection
both rates are calculated in frames per second
(if the movement is to look accurate on the screen, the rate of shooting should correspond to the rate of projection)
Fast-Motion Effect
a film is exposed at fewer frames per second than the projection rate
Slow-Motion Effect
the more frames per second shot the slower the screen action will appear
What is the fast-motion effect typically used for?
to grab our attention and accelerate the pace, whisking us through a setting to the heart of the action
What is the slow-motion effect typically used for?
expressive purposes, to render sports events in detail, to suggest that the action takes place in a dream or fantasy, to convey enormous power, for emphasis- dwelling on a moment of spectacle or high drama
Ramping
varying the frame rate during shooting
alters exposure- must be coordinated with lighting
Time-lapse
a very low shooting speed is required
High-speed
the camera may expose hundreds or thousands of frames per second
What is the function of the freeze-frame effect?
can underscore a piece of action or a line of dialogue, suggest a character’s memory, and suggest the story action hasn’t been resolved
Freeze-Frame Effect
when a single frame of content shows repeatedly on the screen—”freezing” the action
Perspective
a set of spatial relations organized around a viewing point
What does the lens of a photographic camera do?
gathers light from the scene and transmits that light onto the flat surface of the film or video chip to form an image that represents size, depth, and other dimensions of the scene
