list principles of design
balance contrast emphasis pattern space scale/proportion unity variety movement/rhythm
describe balance
illustates visual weight
describe contrast
two or more opposing elements
describe emphasis
shapes the center of interest
describe pattern
makes sense of visual world with regularity
describe space
dictates the organized/disorganized distribution of visual elements
describe unity
relationship between elements
describe variety
use of different elements
describe movement/rhythm
adds excitment by showing action
describe scale/proportion
realtionship between relative sizes of elements
name compositional concepts
rule of thirds symmetry leading lines frame within a frame triangular diagonal
purpose of rule of thirds
leads eye around the image
purpose of symmetry
creates balance and harmony
purpose of leading lines
leads the eye around the image
purpose of frame within a frame
adds depth
purpose of triangular comp
stability
purpose of diagonal comp
