- Four Ways to Judge the Relative Size of an Object
-
1. knowledge of the object
2. relation to the screen size
3. environment and scale
4. relation to a person - Magnetism of the Frame
- the pull that the frame exerts on objects within the frame
- Attraction of Mass
- graphic mass attracts graphic mass. the larger an object, the larger it's attraction power
- Assymetry of the Frame
- the right and left side of the video screen are unequal in visual prominence. The right side is said to command more attention than the left.
- Uphill/Downhill Diagonals
- We seem to read diagonals from left to right
- Screen Left & Right Assymetry
- we tent to pay more attention to that on the right then left. we move from middle to left to right with out eyes
- Figure/Ground (light)
- tendency to organize a scene into figures hat lie in front of a grbacground. We perceive the ground as being more stable than the figures
- psychological closure
- mentally filling in nonexistant information to arrive at a stable pattern
- gestalt
- the configuration we perceive through closure. the pattern is complete here
- vector
- a perceviable force with a direction and magitude. a element that leads us to a specific space/time direction
- graphic vector
- vector created by a line or elements ina way that suggest a direction
- index vector
- vector that is created by something that points unquestionably
- motion vector
- vetor created by object actually moving a specific direction
- vector magnitude
- degree of directional certainty and force, the amount of energy we perceive an object to have, screen size, graphic mass, and speed
- continuing vectors
- vectors that suceed each other in the same direction
- converging vectors
- vectors that move towards each other
- diverging vectors
- vectors that move in opposite directions
- stages of balance
- stablie, neutral, labile
- labile balance
- imbalance created by graphic weight, frame magnetism and vectors pushed to structural limit
- Golden Section
- divisions of the screen, cutting the screen into 5 parts
- rule of thirds
- dividing the screen into thirds, acheives a pleasing composition when object lies on the thirds
- illogical closure
- tendency to smooth continuity of vectors, by grouping objects together to stablize a picture, eeven if they don't belong together
- premature closure
- Premature closure occurs when the upper or lower edges of a screen coincides with the natural dividing lines.
- depth of field
- the area along the z-axis that is in focus
- z-axis
- the axis in the coordinating system that defines depth, the imaginary
- graphic depth
- the illusion that creates the 3D space on a 2D surface, overlapping planes, relative size, height in plane
- height in plane
- assuming the camera is shooting parallel to the ground, you will perceive an object as being more and more distance the higher it movse up in the picture field until it has reached the horizontal line
- linear perspective
- horizontal linear lines that coverge towards the distance at a vanishing point
- aerial perspective
- slective focus in a shallow depth of field only a shoer section of the z-axis is in forcus, while rest is blurry
- selective focus
- emphasizing an object in a shallow depth of field through focus while keeping its foreground and background out of focus
- articulating the z-axis
- the place objects or people along the z-axis to serve as 3D space modulators
- blocking along the z-axis
- placing people and their movement towards and away from the camera. intenfiying the 3D element
- negative volume
- empty space that surrounds, or is descibed by positive volumes, ex: empty room that is surrounded by walls
- positive volume
- objects that have substance and can be touched and weighed.
- dominant negative volume
- a lot of space with nothing in it , a lot of objects in a small space. The effects of a dominant positive volume give a sense of emptiness
- dominant positive volume
- a lot of mass, a lot of objects in a small space. The effects of a dominant positive volume give a sense of a crowded area
- importance of context
- allows us to decide how to visualize out shots, whether it be standard tv, hdtv, or movie....
- medium skills
- your ability to understand the technical and aesthetic limitations and potentals of the medium
- animatic
- series of images edited together
- previsualization
- using computer graphics, low cost,(usually 3D) to create rough versions of the shots in a movie sequence.
- deductive visual approach
- moving from general to the specific
- inductive visual approach
- moving from specific to general
- looking at an event
- report what's going on, news
- looking into an event
- telling the viewer what is going on, providing insight, sports
- creating an event
- use effects to change an original event, football fireballs
- Subjective Camera - being discovered
- screen action is aimed directly at us, we feel we are discovered by the action, linked with the event
- Subjective Camera - direct address
- performer speaks directly to the camera, to the audience
- objective time
- time measured by the clock, clock time
- subjective time
- duration we feel
- event density
- relative number of event details that occur within a brief clock time period
- event intensity
- relative energy and relative significance we perceive about a specific event
- experience intensity
- number of relevant experiences to which we are subkective simultaneously or in rapid succession
- aethetic entropy
- the energy present at the live time of an event, but decresses as time passes
- film motion
- an illusion, makes us see things that move in our mids
- video motion
- the constant moving electron beam that scna many phosphorus dots on the inside of a television set of individual pixels
- basic structure of film
- an assembly of still frames that when put together with others and enlarged, create motion
- basic structure of video
- digital consistant movement
- motion paradox
- whenever an object is simultaneously in motion and at rest, riding in a car or airplane
- figure/ground reversal
- illusion created when two objects are in motion, but one moves faster than other
- perceived speed
- how fast or how slow we sense something is moving on screen
- z-axis motion
- determined by the focal length, you can misjudge where an object may be
- perceived object speed: wide angle lens
- exaggerates the perceived z-axis speed with which an object appears to move toward or away from the camera, image size changes considerably
- perceived object speed: narrow angle lens
- slow perceived z-axis speed with which an object appears to move toward or away from the camera, image size doesn't change considerably
- looking up/down motion
-
ground level makes object appear fast
aerial view makes object appear slower - aesthetic effects of slow motion
- allows us to see better, frees an object from gravity, anticipation, surreality
- accelerated motion
- show that not only is the obeckt faster than normal, but also erratic
- aethetic effects of accelerate motion
- comic effect, dramatic effect,
- scene time
- length of a scene, subdivision of a sequence

- secondary motion
- the camera motion; pan, titlt, boom, dolly, truck, arc...
- tertiary motion
- sequence motion, movement and rhythm influcence through shot changes
- editing
- selecting and sequencing those aprts of an event that contribute most effectively to its clarification
- continuity editing
- the structuring of on-and-off screen space and on establishing and maintaining the viewer's mental map
- mental map
- helps you make sense of where things are on and off screen, where they are going, or where they are supposed to be in on and off screen space
- index vector line
- line of conversation, one eighty line, important for maintaining the established vector continuity
- complexity editing
- used to intensify an event and reveal its complexity, diving deep into the event
