The Shot Flashcards
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
Contrast
in cinematography, the difference between the brightest and darkest areas within the frame
Exposure
the adjustment of the camera mechanism in order to control how much light strikes each frame of film passing through the aperture
Filters
a piece of glass or gelatin placed in front of the camera or printer lens to alter the quality or quantity of light striking the film in the aperture
Rate
in shooting, the number of frames exposed per second
in projection, the number of frames thrown on the screen per second
if the two are the same, the speed of action will appear normal, whereas a disparity will create slow or fast motion
the standard rate in sound cinema is 24 frames per second for both shooting and projection
Ramping
changing the speed of photographed motion within a single shot, as when the action in a fight scene suddenly goes from regular speed to slow motion and back
this effect can be achieved during shooting or postproduction
Lens
a shaped piece of transparent material (usually glass) with either or both sides curved to gather and focus light rays
most camera and projector lenses place a series of lenses within a metal tube to form a compound lens
Focal Length
the distance from the center of the lens to the point at which the light rays meet in sharp focus
the focal length determines the perspective relations of the space represented on the flat screen
Zoom Lens
a lens with a focal length that can be changed during a shot
a shift toward the telephoto-lens range enlarges the image and flattens its planes together, giving the impression of magnifying the scene’s space
a shift toward the wide-angle range does the opposite
Focus
the degree to which light rays coming from the same part of an object through different parts of the lens reconverge at the same point of the film frame, creating sharp outlines and distinct textures
Depth of Field
the measurements of the closest and farthest planes in front of the camera lens between which everything will be in sharp focus
a depth of field from 5 to 16 feet, for example, would mean everything closer than 5 feet and farther than 16 feet would be out of focus
Deep Focus
a use of the camera lens and lighting that keeps objects in both close and distant planes in sharp focus
Racking Focus
shifting the area of sharp focus from one plane to another during a shot
the effect on screen is called rack-focus
Special Effects
a general term for various photographic manipulations that create fictitious spatial relations in the shot, such as superimposition, matte work, and rear projection
Superimposition
the exposure of more than one image on the same film strip or in the same shot
Rear Projection
a technique for combining a foreground action filmed earlier
the foreground is filmed in a studio, against a screen
the background imagery is projected from behind the screen
the opposite of front projection
Matte Work
a type of progress shot in which different areas of the image (usually actors and setting) are photographed separately and combined in laboratory work
Framing
the use of the edges of the film frame to select and to compose what will be visible onscreen
Aspect ratio
the relationship of the frame’s width to its height
the standard Academy ratio is currently 1.85:1
Academy Ratio
the standardized shape of a film frame established by the Academy of Motion Picture Acts and Sciences
in the original ratio, the frame was 1 1/3 times as wide as it was high (1.33:1)
later, the width was normalized at 1.85 times the height (1.85:1)
Masking
in exhibition, stretches of black fabric that frame the theater screen
masking can be adjusted according to the aspect ratio of the film to be projected
Anamorphic Lens
a lens making widescreen films using regular Academy ratio frame size
the camera lens takes in a wide field of view and squeezes it onto the frame, and a similar projector lens un-squeezes the image onto a wide theatre screen
Mask
an opaque screen placed in the camera or printer that blocks part of the frame off and changes the shape of the photographed image, leaving part of the frame a solid color
as seen on the screen, most masks are black, although they can be white or colored
