Ch 4 - Depth, Movement, and Time Flashcards
x-axis
width
y-axis
height
z-axis
depth
illusion of depth
creation of appearance of 3rd dimension within 2D media
perspective
perception of depth and distance from particular point of view (linear perspective represents 3D space in 2D with parallel lines converging at horizon)
rack focus
camera technique in which focus is shifted from one subject on plane of action to another on different plane of action
directed tension
sense of implied movement created by graphics lines or vectors within frame/by inherent tension of certain positions within frame
vector
- ) strong diagonal line either implied/existing in frame that suggests movement
- ) type of computer graphics created from mathematical formula that can be rescaled while maintaining quality
persistence of vision
human brain fills in gaps between rapidly projected individual frames of an action that has been broken down into series of still iimages
phi phenomenon
perceptual occurrence where human eye perceives 2 closely proximate lights flashing in quick succession as movement
blocking the talent
part of production process where director makes decisions about talent position and movement related to camera position
tripod
3-legged stand with spreaders/supports that keep legs steady
pedestal
heavy wheeled mount used in studio production (moves camera up and down)
dolly
tripod on wheels (moves on z axis closer/further to subject)
crane
long-armed, counter-weighted camera device that allows sweeping camera moves thru space
pan
camera pivots right or left
tilt
camera pivots up and down
