Term
z- axis
Definition
- An imaginary line that extends from the front of the camera lens to the horizon

- Used to help create the illusion of depth, that extends from the front of the camera lens to the horizon.

- Important because TV is two dimensional and can help add depth.-
Term
overlapping planes
Definition
Use the foreground to force viewer to focus on object in background. You have one object in front overlapping another object in the background creating the illusion of depth.
Term
relative size
Definition
If you know how big an object is or if you can guess its size by other clues, you can estimate its distance from the camera by its relative size.

- If you have two objects that are similar in size, and one appears smaller than the other on screen, you will perceive the smaller object as farther away.
Term
height in plane
Definition
- If the camera is shooting parallel to the ground, an object will appear more distant the higher it moves up in the picture field (until it reaches the horizon line).

- This depth cue is not the most reliable, because the mobility of the camera causes the horizon line to constantly shift.
Term
linear perspective
Definition
- Use different angles rather than straight on to make the object sit on the z-axis.

- Move the camera to an angle of at least 30 degree or 45 degree NOT 180 Degree. (flat shot)
Term
aerial perspective
Definition
- Natural moisture and dust in our atmosphere makes us see distant objects less clearly than objects that are close to us.

- If you are painting scenery, background objects should be slightly bluer and less sharp than foreground objects, which will give the illusion of depth.
Term
crowding effect
Definition
- used to stimulate depth

- Adding a bunch of objects to almost fill the screen
Term
wide angle
Definition
- Objects along the z-axis look stretched out by the wide-angle lens, so overlapping planes, while still present, are not the strongest indicator of depth.

- The wide-angle lens accelerates the convergence of parallel lines.

- Lines come together more than when seen normally.

- The z-axis space is elongated.
Term
narrow angle
Definition
- The narrow-angle lens makes objects appear closer together along the z-axis than they really are.

- Objects look squeezed, and the z-axis itself appears shorter.

- The narrow angle lens reduces convergence and so reduces the illusion of depth.

-Horizontal lines do not converge as easily as with a normal or wide angle lens.

- The z-axis space is shortened.
Term
selective focus
Definition
- Changes the focus on an object at different distances along z-axis.

- One object is out of focus, the other is on focus adding the perception of depth.
Term
rack focus
Definition
- focus involves changing the focus from one object to the other (on the z-axis).

- Requires Narrow angle lens
Term
basic z-axis structure
Definition
- Foreground – closest to the camera
- Middleground – middle
- Background – farthest from the camera
Term
volume duality
Definition
- Interplay between positive and negative volumes

- Volume duality is the dynamic changing of relationship between negative and positive volumes.
Term
z-axis articulation
Definition
- Placing positive volumes along the z-axis to help the camera distinguish among various depth planes.
Term
z-axis blocking
Definition
- Refers to placing people and their movements primarily along the z-axis – toward and away from the camera.

- Creates a dynamic volume duality

- Intensify the illusion of third dimension
Term
negative volume
Definition
- Characterized by empty space delineated by positive space most of the time. Remember that negative volume is ALWAYS delineated by positive space, otherwise it is not defined as volume.
Term
positive volume
Definition
- Characterized by mass and substance (objects, humans, etc)
Term
dominant volume
Definition
- Confine movement

- Feeling restricted

- Stuff small spaces with many things
Term
open set
Definition
- A set with fundamental objects (window, walls, door, desk)
Term
depth of field
Definition
- Range of distance over which objects in a picture will remain in critical focus.
Term
2 types of depth of field
Definition
- shallow (where there is not a long range of objects in focus)

- great (where there is a long range of objects in focus).
Term
narrow angle lens distortion
Definition
- A narrow angle lens (long focal length, zoomed in) reduces negative space and crowds objects.

- It shortens the z-axis

- Causes mass elements of visual pollution

- Rob of individuality

- Danger situations (closeness of cars, assault)
Term
wide angle lens distortion
Definition
- A wide angle lens (short focal length, zoomed out) exaggerates size relationships

- A wide angle lens stretches the z-axis

- An object close to the camera appears much larger than a similarly object placed just - a short z-axis distance away.

- Message: importance, order, power, fear, stress, danger
Term
visualization
Definition
- thinking in pictures, or in individual shots or brief sequences.
Term
storyboard
Definition
- A series of visualizations

- It usually consists of a series of sketches in sequence.

- The storyboard is very detailed, and is a key part of preproduction.

- Storyboard shows sketches or still photos of the key points of view of an event in their proper sequence.
Term
deductive visual approach
Definition
means moving from the general to the specific. Technically this means starting from a wide shot and closely getting to a close-up.

- In this way you are setting up visually all the elements of the story (time, characters, objects, location, etc)
Term
inductive visual approach
Definition
means that you go from details of the event to a general overview.

- Begin with a close-up of a significant detail, then follow with a series of close- up details.

- May end the sequence with a wider orientation shot.

- Compels the viewer to use psychological closure.
Term
looking AT an event
Definition
report an event the way it is. Think about someone who OBJECTIVELY observes an event.
Term
looking INTO an event
Definition
you are scrutinizing the event as closely as possible, to look behind what is obvious. What is the essence of what has been shown?

- Communicate to the viewer what it would be otherwise overlooked.
Term
creating an event
Definition
means that you are using the technical devices and potentials of the medium to build a unique screen event that depends entirely on the medium.
Term
field of view
Definition
- refers to how far away or close we show an object or person on-screen.

- Also refers to how much territory a shot includes.
Term
types of fields of view
Definition
 Extreme long shot (ELS)
 Long shot (LS)
 Medium shot (MS)
 Close-up (CU)
Extreme close-up (ECU)
Term
point of view
Definition
It can mean a certain character’s perspective.

- Point of View means that the camera takes on a bias of looking.

- It no longer describes an event, but comments on it from a certain perspective.

- Refers to the camera’s narrative involvement.
Term
POV: looking up/ looking down
Definition
- A low-angle or below-eye-level shot can give the subject a feeling of dominance, power, or authority.
Term
POV: objective viewpoints to subjective viewpoints
Definition
- With such a subjective camera shot, you can indicate what the person is thinking about or noticing by what you show.
Term
POV: subjective camera
Definition
- The camera is a participant in an event.
- Assuming the character’s point of view
Term
angles
Definition
- Shifting a camera’s viewpoint
Term
clock time
Definition
- A precise moment in time
- When a movie or TV show starts or stops
- Clock time exists whether in real life or on fictional television.
Term
running time
Definition
- The length of a program
- Films usually have longer running times than TV shows.
Term
sequence time
Definition
- how long several related scenes run when added together
a subdivision of running time.
Term
scene time
Definition
- length of a scene
- a small part of an event that usually takes place in a single location within a single story time span
- a subdivision of sequence time.
Term
shot time
Definition

Term
timing
Definition
- The control and manipulation of objective time.

- The structuring of subjective time.
Term
types of subjective time

Term
primary motion
Definition
event motion that occurs in front of the camera: performers, vehicles, any action at all.
Term
secondary motion
Definition
camera motions such as pan, tilt, pedestal, boom, dolly, truck, arc, and zoom.
Term
tertiary motion
Definition
sequence motion, created by shot changes or transitions: cut, dissolve, fade, wipe.
Term
perceived motion
Definition
- When something changes its position more or less continuously when compared to a stable environment, we perceive motion.

- A car moving toward or away from us

- A child running past a swing and slide on a playground.
Term
frames
Definition
- 24 frames per second

- The basic structural unit of film
Term
perceived speed
Definition
- refers to how fast or slowly we sense something to move on-screen.

- It includes object speed (how fast the object was actually traveling when recorded)

- the focal length of the lens (a specific zoom position), and

- blocking (the camera’s point of view relative to the moving object).
Term
lens choice and blocking
Definition
- the perceived screen motion is greatly dependent on the focal length of the zoom lens position and where you place the camera in relation to the event.
Term
slow motion
Definition
- it’s when an event appears to be moving considerably more slowly on the screen than it would normally while being photographed.
Term
synthetic motion
Definition
- Motion on screen can be synthetically generated

- Each frame must be created digitally.

- In animation, the process is done by drawing each frame.
Term
fade
Definition
a gradual transition to black (fade out) or from black (fade in); signifies a definite beginning or ending to a sequence; fades will stop the pace of your show, so use them only when indicating and ending and/or a beginning
Term
dissolve
Definition
gradual transition from shot to shot
Term
jump cut
Definition
- occurs when a subsequent shot is not sufficiently different in field or angle of view, and the image seems to jump in position on the screen.
Term
continuity editing
Definition
- is a cutting method designed to maintain a smooth and continuous flow of time and space from one shot to the next
Term
mental map
Definition
essentially a picture of the entire setting in your head, whether all of it is on screen or not.
Term
graphic vector continuity
Definition
- they are weak

- In an outdoor scene, keep the horizon at the same level throughout the scene.

- Keep it consistent unless you move the camera to a new perspective during a shot.

- In an indoor scene, the back of a couch or a windowsill in the background should not change position.
Term
continuing index vector
Definition
- If you start with an establishing shot of someone looking at an object, you must keep the index vector (the direction of their eyes) consistent when cutting to a close-up.
Term
converging index vector
Definition
- If you begin with a 2-shot with two people looking at one another (converging index vectors), the vectors must maintain their convergence in subsequent close-ups of each person.
Term
diverging index vector
Definition
- Just like converging index vectors, if you begin with a 2-shot with two people looking away from each other (diverging index vectors), the vectors must maintain their divergence in subsequent close-ups of each person.
Term
basic principle of index vector line
Definition
DON'T CROSS THE 180o AXIS
Term
motion vector continuity
Definition
- The direction of motion of an object cannot change from shot to shot.
Term
motion vector line
Definition
- Any motion vector other than a z-axis vector helps establish the motion vector line.

- Your camera must go on one side or the other of the motion vector line to maintain continuity.
Term
continuity of environment
Definition
- Your scene should have the same elements in it from shot to shot
- Costumes and set pieces should remain consistent throughout a scene.
Term
color continuity
Definition
- Keep colors and lighting consistent between shots unless you change the event to a different place or time.
Term
subject continuity
Definition
- Avoid cutting from an extreme long shot to an extreme close-up (in a crowded room, for example).
- Your audience may not be able to tell whether the people in the close up were the ones in the long shot.
- Avoid cutting between extreme angles (unless it serves your purposes).
Term
action continuity
Definition
› Use cuts during the action (a single primary motion) to maintain continuity, not before or after it.
› If you cut before or after an action, you emphasize the beginning or end of a motion vector.
› If you cut during a secondary (camera) motion (pan, tilt, zoom) , you should continue the same motion in the next shot.
Term
montage
Definition
- the juxtaposition of two or more separate event images that combine into a new whole (gestalt principle).
Term
analytical montage
Definition
- Analyze an event for its thematic and structural elements.

- Select the essential elements.

- Synthesize those elements into an intensified screen event
Term
sequential analytical montage
Definition
a scene is condensed into its key developmental events.

- It tells a story in shorthand – the main event is not actually shown but implied.
Term
sectional analytical montage
Definition
examines an isolated moment of an event from several viewpoints, revealing its tension and emotional power.
Term
idea associative montage
Definition
- takes two seemingly disassociated events and puts them together to create a third idea or concept (tertium quid) not contained in either of the first two events.
Term
comparison idea associative montage
Definition
uses shots that compare and contrast two thematically related events to reinforce a theme or basic idea. Ex: a dog looking for food in trash, it is juxtaposed with a homeless person doing the same.
Term
collision idea associative montage
Definition
takes two opposite events and compares them in stark contrast to reinforce a basic idea or feeling. Ex: Poor child in rags walking along a dirt road + rich yuppie driving a BMW convertible = excessive materialism
Term
metric montage
Definition
- A rhythmic structuring device

- Consists of a series of related or unrelated images that are flashed on the screen at more or less equally spaced intervals.
Term
television
Definition
an audio visual medium
Term
reflection of reality
Definition
- Sound is a primary communication factor.

- TV is mainly reality based, shows draw on real events

- For example, if all you have is a long hallway, and you want to turn it into a hospital wing, just add the sound of an intercom call for a doctor
Term
low- definition images
Definition
- The size of the TV screen is relatively small

- The picture resolution is low (analog, anyway)

- TV builds stories inductively, using a series of close-ups that limit the available information on-screen.

- Sounds are added to supply additional information so the audience can keep track of what is going on.
Term
production restrictions and technical limitations
Definition
- These microphones are usually placed on booms so that they will not interfere with the shots.

- This restricts the area each mic can “hear” or pickup, even with high-quality microphones.
Term
audio/ video balance
Definition
- Picture and sound should be balanced in quality.

- A high-quality audio signal should not be paired with a low-quality picture because the high-energy sound will overpower the low-definition picture.

- Now that HDTV has improved the picture quality of TV, the sound quality must be better as well.
Term
film sound
Definition
- Film, in contrast to television, is primarily a visual medium.

- Films can be made without sound

- This does not mean that sound is not important, because film’s big, high-definition images require excellent sound.
Term
nonliteral sound
Definition
sounds include most background music and other sounds that might influence our feelings in some way.
Term
literal sound
Definition
speech and environmental sounds, even sound effects.
Term
information sound
Definition
- To communicate specific information verbally through dialogue, direct address, or narration.
Term
outer orientation function
Definition
- Similar to the same function of light: orientation in space, in time, to situation, and to external event conditions.

- One sound can fulfill several functions: If you hear a foghorn blowing you know that - we are near water (location),
