For your homework... Using this page as a guide, write a quick summary in your own words what the "Gestalt Principals" are.
With a second (or possibly third) paragraph select a single Gestalt principle and explain it using at least 2 example images from the web.
Gestalt is a psychology term which means "unified whole". It refers to theories of visual perception developed by German psychologists in the 1920s. These theories attempt to describe how people tend to organize visual elements into groups or unified wholes when certain principles are applied. These principles are:
Similarity occurs when objects look similar to one another. People often perceive them as a group or pattern. The example to the left (containing 11 distinct objects) appears as as single unit because all of the shapes have similarity. Unity occurs because the triangular shapes at the bottom of the eagle symbol look similar to the shapes that form the sunburst. When similarity occurs, an object can be emphasized if it is dissimilar to the others. This is called anomaly.
Continuation occurs when the eye is compelled to move through one object and continue to another object. Continuation occurs in the example above, because the viewer's eye will naturally follow a line or curve. The smooth flowing crossbar of the "H" leads the eye directly to the maple leaf.
Closure occurs when an object is incomplete or a space is not completely enclosed. If enough of the shape is indicated, people perceive the whole by filling in the missing information. Although the panda above is not complete, enough is present for the eye to complete the shape. When the viewer's perception completes a shape, closure occurs.
Proximity occurs when elements are placed close together. They tend to be perceived as a single group. The nine squares to the left are placed without proximity. They are perceived as separate shapes. However, if they were placed within a similar area they would seem to exist as a complete unit. When the squares are given close proximity, as you see here to the left in the second image, unity occurs. While they continue to be separate shapes, they are now perceived as one group.
The eye differentiates an object from its surrounding area. A form, silhouette, or shape is naturally perceived as a figure (object), while the surrounding area is perceived as the ground (background). Balancing both figure and ground can make the perceived image more clearly defined. Using unusual figure/ground relationships can add interest and subtlety to an image. In this image to the left, the figure and ground relationships change as the eye perceives the the form of a shade or the silhouette of a face. With the second image, the image uses a complex figure/ground relationships which changes upon perceiving leaves, water and tree trunk.
