Final answer:
In the principles of hair design, the comparative relationship of one thing to another is known as proportion. It is crucial for creating a balanced and visually appealing design. Scale, which is closely related to proportion, refers to the relative size of forms and can provide emphasis or create illusions in a composition.
Step-by-step explanation:
In the principles of hair design, the comparative relationship of one thing to another is called proportion. Proportion refers to the relationship of parts of a body or form to one another and of the parts to the whole, such as the size of the head in relation to the entire body. Understanding proportions is essential as it creates a harmony and balance in the visual aspect of a design, making it pleasing to the eye.
Another principle closely related to proportion is scale, which shows the relative size of one form in relation to another. Scale is significant as it helps provide focal points or emphasis in an image, and it can create illusions of depth or highlight relationships of size relative to the human body or other objects. American sculptor Claes Oldenburg's works, like the Spoonbridge and Cherry sculpture, exemplify the use of unexpected scale to create a playful and impactful visual experience.
Proportion and scale are ways to express a value judgment about a composition. They are among the various principles, such as unity and balance, that can produce visual effects that contribute to the composition's overall aesthetics. These principles are like the 'glue' that helps to combine different elements into a coherent and visually appealing image.
