Element of Design - Depth (perspective)
Perspective is another element of visual design. In traditional art forms such as paintings, drawings, posters, sketches or in modern art forms such as photographs, videos, animations, the visual media has only 2 dimensions – length and width. Depth in an image is achieved by tricking the eye to see depth(3-D) on a flat surface(2-D). It is possible to achieve the illusion of depth in a number of ways. The two main techniques are non-linear and linear.
Value - Lighter values look like they are farther back and darker value look like they are closer.
Colour – objects in the background usually seem fuzzy, distant and are more neutral. Objects in the foreground have colours that are usually more vibrant and bright.
Size variation - Smaller objects look farther away in the distance in relation to larger objects which look closer.
Overlapping – when two objects in a picture overlap each other, the implication is that the object on top is nearer to the viewer and the object being overlapped is farther away.
Position – by placing an object higher on a page, it makes the object appear farther back in relation to objects that are placed lower on the page.
Non-linear perspective achieves depth by using several possible techniques:
