VC-Triangle, Tool To Evaluating Quality of Visual Aid
Principles of visual communication describe the various concepts that are used to arrange the basic structure of the elements of visual aid.
How these principles are used in the art or design defines the content or message being expressed, meaning one principle can be used in different ways to express different messages.
There are several principles of visual communication that are applied in art, web or any other design, and they help a lot in portraying the specific message being relayed.
Special Note: I decided not to put illustrative image on each of the points below to reduce the loading time of this page — more images will take take time to fully load the page.
Emphasis – show the subject
Emphasis is putting stress on certain on your subject to be prominent. It is concerned about drawing the viewers’ interest to a particular part of the design by ensuring it stands out among other areas. It is sometimes called dominance.
This can be done by varying the color, texture, weight, size, shape and many more instead of using equal element emphasis which would make the art look flat.
In Photography , techniques like panning, aperture manipulation and narrow lighting are only few ways to emphasize your subject. The well-known rule to emphasis your subject is the Rule of thirds.
Variety – get raid of monotony
Variety is used when do not want monotony and obtain diverity to increase the visual interest in the artwork. A visual aid which makes use of different elements like lines, textures, shapes, form and color would show the artist’s or designer’s desire for variety.
Harmony – make it pleasing
Harmony is the pleasing combination of element. It is the agreement of each entity. It is like honey and pancake, coffee and cream and puto and dinuguan. Harmony tells how well the elements within your frame are visualized to a stunning photograph.
It is the oneness of composition which is sometime refered as unity. This principle is used to keep elements together, by pulling the similar ones together and keeping those that are different apart. It is used to ensure the elements fit together to create harmony and completeness in all the parts of the design.
Do the major elements on the frame are connected to the other in terms of color, texture, line, value and so on? Are they seen as single undivided thing? If they don’t, you photo has no ‘Unity’.
Balance – maintain the equilibrium
Balance is the one which maintain the equilibrium in you composition. Its three major types are the proper (symmetrical) balance, the improper (asymmetrical) balance, and the radial balance. Symmetrical balance is sometimes called formal or Mathematical balance and ssymmetrical balance is sometimes called Informal or visual balance.
Symmetrical balance describes designs which have equal and same elements on either side while asymmetrical balance is used to describe designs with different elements, though still looking balanced visually; radial balance applies an arrangement of elements around a central object.
Proportion – do not distort
Proportion is sometime replaced by the word ‘scale’ in the list of principle of composition. It is used to describe how one part of the design or art compares with other parts in the artwork. These parts should balance well to create a good visual representation. When comes to photography is usually done by estimation base on the real world. This principle could help you identify the distance of each object in the frame from the camera.
Rhythm – stay on the move
Rhythm is the harmonious repetition of composition elements to depict movement. It can be used in various forms such as linear, repetition, alternation or gradation to create an exciting movement which is easy to comprehend. Using a variety of contrasting elements makes the rhythm more exciting.
Contrast – show the difference
Contrast simply means difference between or among the elements in your composition. This is important when you want to capture improper balance out of the scene. It could be contrast between lines, shapes, colors and textures or contrast between sizes. Contrast usually goes together with ‘variety’ when used in art or design work.
All of these help define the structure of the various elements of design and how they are used. They give the work more value and appeal when used appropriately.
Pattern – do it all over again
Pattern is the repeatation of elements or group of elements like shapes, colors, lines and dots which have regular or decoartive effect. I graphic design, patterns are often use as backround posters, brochures and other types of projects.
Patterns can be crated manually or by the of a design software like Adobe Photoshop.
How to Use the VC-Triangle
You notice that the emphasis is first on the list and it is followed by variety then unity and followed by the rest of the rest of the principles. This means that when evaluate the quality of your design, you are not advised to immediate jump into checking whether the design it balance or not.
You need to consider first your subject or you message, and when you are sure that subject is on the focal point, you can proceed to evaluate whether the design is not boring or monotonous then proceed to the next criteria.
It is a step by step process. Start from the bottom side of the triangle then move clockwise. After that, proceed to the fist layer, which is balance, then move upward to harmony and so on.
I hope that this tool can help you to produce better and effective visual aids.
