And to finish things up…

So continuing from where we were yesterday…so…

Gastalt-

Sometimes considered a distinct principle of design, gestalt is the concept that “the whole is greater than the sum of its parts.” Gestalt is a concept from psychology, where theorists note that humans have a propensity to conceptually group things together to make a meaningful whole. When viewing designs, humans apply this principle unconsciously by seeing connections and relationships among and between the elements in the design. The overall perception of gestalt in a design is created through harmony, unity, balance, proportion, proximity, and other visual cues. Designers can use this principle to create visual connections and relationships that clarify and strengthen the overall “feel” and meaning of the design.

Harmony-

As with music, graphical elements can be said to be working in harmony – the individual parts come together as visually compelling and a meaningful whole. Disharmony can also be used just as it is in musical compositions: to enhance the emotional complexity, to challenge the viewer, and to provide a contrast within the overall composition.

Movement-

Movement is creating an instability, making motion to blur the image. Movement can be achieved by using graphic elements that direct the eye in a certain direction such as arrows that point the way overtly or a series of lines or dots that get progressively larger or smaller, creating a more subtle sense of movement. Movement can be accomplished simply by using a photograph or clip art of something moving – a runner – as opposed to something stationery – a person standing.

Proportion-

This indicates the relative visual size and weight of particular graphical elements in a design composition.

Proximity-

Closeness or distance of individual design elements. Close proximity indicates a connection.

Repetition-

Repeating a sequence; having it occur more than a few times. In design, repetition creates visual consistency in page designs, such as using the same style of headlines, the same style of initial capitals, or repeating the same basic layout from one page to another.

Excessive repetition (monotony) may lead to boredom and uninteresting compositions. If one cannot avoid excessive repetitions for any reason, do not forget to add some visual breaks and white spaces where eyes can rest for a while.

Rhythm-

Successful designs have an effective ebb and flow. Text and graphics should seem to be paced and patterned. Spacing is an effective application of this principle. Second, human beings are more comfortable with variation in general. Psychologically, most any serious lack in variation of anything (a solid, a line, a sound, a situation) can become very boring. Adding a little variation at non-specific intervals (every now and again) gives most any design an interesting appeal as long as it is not overdone.

In setting type, rhythm can be created or disrupted. Compare the gibberish strings, “as erav mono ewone zenao oro remuna oravanam” and “githol urtym reislyt quadirit”. Notice how the latter seems to be more organic and readable than the former. This is resultant of two things. One, the eye more easily follows abnormalities and variation, like an ocular foothold. Too-narrow columns result in over-hyphenation. Images that interrupt a passage of text can break the rhythm for the reader and they could disturb the visual appearance of the page.

Unity-

Unity creates a feeling of wholeness. Unity is usually achieved when the parts complement each other in a way where they have something in common. Unity can be achieved through the use of the same color, or tints of the same color, or using a similar graphic style for illustrations.

Whitespace-

Areas of a design devoid of text or graphics. White space includes margins, gutters, space between lines of type (leading), off-set of text from images (text wraps) and any other part of the page that is empty. White space is also analogous to “negative space” where “positive space” is defined as images, blocks of text, and other graphical elements. In graphic design, the white space, or negative space, is considered an important element of the overall design. It is used – and evaluated – based on the same criteria as the rest of the elements in the design. White space can add to or detract from the balance, unity, harmony, rhythm, and overall success of a design. White space can provide emphasis, contrast, and movement. It can be used for repetition and pattern, and work within various relationships with other elements of the positive and negative spaces in the design.

Once again you can find these on Wikipedia, but i thought it would be easier for you to see it from me. http://en.wikibooks.org/wiki/Graphic_Design/Principles_of_Design#What_is_Graphic_Design.3F
