3 - Gestalt Theory Flashcards
What is Gestalt
In the 1920s, a group of cognitive psychologists in Germany developed a series of theories of visual perception known as the Gestalt Principles. These laws explain our perceptual tendencies and describe how humans typically see objects by grouping similar elementes, recognizing patterns and simplifying complex images. Artists use these principles to engage viewers via powerful “tricks” of composition and best practice design standards.
What is the primary objective of a good lighting?
It’s to show the viewer where to look.
Six examples of the gestalt Laws
Law of similarity, law of pragnanz or the Law of good figure, law of proximity, law of continuity, law of closure, law of common region.
Similarity principle
Similar objects will be counted as the same group and this technique can be used to draw a viewer’s attention. In lighting this principle would be grouping with light and shadow.
Simplicity principle(Pragnanz or Good Figure)
A stimulus will be organized into as good a figure as possible…When learners are presented with visuals, there ir an unconscious effort to simplify what is perceived onto what the viewer can understand. In lighting it is pretty compulsory to have a clear and simpoe read on a shot. We do not want the viewer to be guessing if this is light or shadow.
Why the foreground area of a shot will be in shadow very often?
Because it guides the eye
Proximity principle
THe law of proximity states that items placed near each other appear to be a group. The brain tends to group objects that are close to each other.
Continuation principle
Continuation is the eyee’s instinctive action to follow a direction derived from the visual field.
Figure and Ground principle
Negative or empty spaces will likewise be organized and grouped. For example, two different foreground colors let the viewer percieve different things from the same illustration.
Closure principle
Patterns or objects that cotinue in one direction, even if interrupted by another patter, are perceived as being continuous. Our mind will tend to close gaps and complete unfinished forms.
Unity and Harmony principle
Unity impliesthat a congruity or arrangement exists among the elements in a design; they look as through they belong together, as though there is some visual connection beyond mere chanve that has caused them to come together. The elements of the composition appear to beling together, relate to each other, and to otherwise visually agree.
Common fate principle
Humans percieve visual elements that move in the same speed and/or direction as parts of a single stimulus. A common example of this is a flock of birds.
Two of its more important aplications:
Emphasis(principle of focal pint) and Balance.
Every visual presentation needs a focal point, also called:
center of interest or point of emphasis
A composition may have more than one focal point, but one should “ “
dominate
An image without emphasis is like
wallpaper, the eye has no particular place to look and no reward for having tried.
Contrast emphasis
Contrast can be achieved with shape, size, color, texture, brightness or even motion. A focal point results when one element differs significantly from other elements. Unique or minority elements within larger groups tend to attract our attention.
Tangent definition
where to edges just touch each other, can produce a strong point of emphasis by creating visual tension
90% of the time you want to avoid “ “
tangents
Can be created intentionally to attract viewer interest; however, most of the time they are accidental and distracting.
tangents
Isolation emphasis
When object defies grouping, by not being near or similar to any other object, it calls attention to itself and becomes a point of emphasis through tension
Using perspective angles and other edges, lead the eye to the focal point
Angle emphasis
Shape emphasis
The brain tends to characterize shape as either rectilinear or curvilinear, by creating an image with primarily one type, the other type becomes a point of emphasis
An angle will cath more or less attention than a circle?
