Term
Lenses
Definition
A glass element on a camera that focuses light rays so that the image of object appears on the surface of the film.
Term
Filters
Definition
A device used to manipulate the amount and or color of light entering the lens.
Term
Film stock
Definition
Thin, flexible material comprised of base and emulsion layers, onto which light rays are focused and which is processed in chemicals to produce film images.
Term
Aperture
Definition
A small, variable opening on a camera lens that regulates the amount of light entering the camera and striking the surface of the film.
Term
Negative
Definition
Exposed and developed film stock from which the master positive is struck. If projected, the negative would produce a reverse of the image, with dark areas appearing white and view versa or, if color film, areas of color appearing as their complementary hue.
Term
Optical Printer
Definition
A machine used to create optical effects such as fades, dissolves, and superimpositions. Most now created digitally
Term
Release Prints
Definition
Reels of film that are shipped to movie theaters for exhibition. Soon to be replaced by digital cinema.
Term
Telecine
Definition
A machine that converts film prints to videotape format.
Term
Panning and Scanning
Definition
Also called full screen, the technique of re-shooting a widescreen film in order to convert it to the original television aspect ratio of 1.33 to 1. Rather than reproduce the original aspect ratio, as a letterboxed version does, a panned and scanned copy eliminates some of the visual information and introduces camera movement and editing that are not in the original.
Term
Aspect Ratio
Definition
The shape of the image onscreen as determined by the width of the frame relative to its height.
Term
Letterboxing
Definition
A process of transferring film to video tapes or DVDs so that the original aspect ratio of the film is preserved.
Term
Take
Definition
A production term denoting a single uninterrupted series of frames exposed by a motion picture or video camera between the time it is turned on and the time it is turned off.
Term
Out-takes
Definition
A scene filmed and processed but not selected to appear in the final version of the film.
Term
Long Takes
Definition
A relatively long, uninterrupted shot, generally of a minute or more.
Term
Time-Lapse Photography
Definition
A technique of recording very few images over a long period of time.
Term
Eye-level shot
Definition
A shot taken from a level camera located approximately 5’ to 6’ from the ground, simulating the perspective of a person standing before the action presented.
Term
High-angle shot
Definition
A shot taken from a camera positioned above the subject, looking down at it.
Term
Long shot
Definition
A camera shot taken at a large distance from the subject. Captures entire human form.
Term
Low-angle shot
Definition
A shot taken from a camera positioned below the subject.
Term
Canted/ dutch Angle
Definition
a shot resulting from a static camera that is tilted to the right or left, so that the subject in the frame appears at a diagonal.
Term
Overhead shot
Definition
A shot taken from a position directly above the action
Term
Camera distance
Definition
The space between the camera and the subject it is filming
Term
Reframing-
Definition
A technique of shifting the camera angle, height, or distance to take into account the motion of actors or objects within the frame
Term
Swish pan
Definition
A pan executed so quickly that it produces a blurred image, indicating rapid activity or, sometimes, the passage of time.
Term
Tilt
Definition
A vertical motion of an otherwise stationary camera.
Term
Tracking Shots
Definition
A technique of moving the camera, on a dolly, along a specially built track. Such shots often trace character movement laterally across the frame or in and out of the depth of the frame.
Term
Dollies
Definition
A platform on wheels, used for mobile camera shots
Term
Crane shot
Definition
A shot taken from a camera mounted on a crane that moves three dimensionally in space.
Term
Aerial Shots
Definition
A shot filmed from an airplane or helicopter
Term
Handheld shots
Definition
A shot taken by a camera that is held manually rather than supported by a tripod, crane, or Steadicam.
Term
Steadicam
Definition
a device worn by a camera operator that holds the motion picture camera, allowing it to glide smoothly through spaces unreacable by cameras mounted on a crane or other apparatus.
Term
Depth of Field
Definition
The distance that appears in focus in front of and behind the subject. Determined by aperture, distance, and focal length of lense.
Term
Rack Focus
Definition
A change of focus from one plane of depth to another.
Term
Split screen
Definition
An optical technique that divides the screen into two or more frames.
Term
Zoom Lenses
Definition
A lens with a variable focal length that allows changes of focal length while keeping the subject in focus.
Term
Over-Exposure
Definition
An effect created when more light than is required to produce an image strikes the film stock, so that the resulting image exhibits high contrast, glaring light, and washed out shadows.
Term
Under-exposure
Definition
An effect created when too little light strikes the film during shooting
Term
Post Production
Definition
The period after principal photography during which editing and looping take place, and special visual effects are added to the film.
Term
Rear projection
Definition
A technique used to join live action with a pre-recorded background image. A projector is placed behind a screen and projects an image onto it. Actors stand in front of the screen and the camera records them in front of the projected background.
Term
Front Projection
Definition
A technique to join live action with pre-recorded background images. A projector is aimed at a half silvered mirror that reflects the background, which the camera records as being located behind the actors
Term
Matte Paintings
Definition
A painting used on the set as a portion of the background.
Term
Fade Out
Definition
A shot transition where shot A slowly disappears as the screen becomes black before shot B appears. A fade in is the reverse of this process.
Term
Dissolve
Definition
A shot transition that involves the gradual disappearance of the image at the same time that a new image gradually comes into view.
Term
Double Exposures
Definition
A technique of exposing film frames. Then rewinding the film and exposing it again, which results in an image that combines two shots in a single frame.
