Answer:
LINE is the most versatile of all of the Elements of Art. We can use line in many ways in photography – to suggest contrast, shape, movement, direction, pattern, rhythm, distance, and more. Differences in width, length and direction of line can impact their meaning and the viewer’s response to them.Use of line can generate psychological responses. For example, curved lines often evoke a sense of calm or restfulness. Conversely, jagged lines may suggest tension or urgency.
Lines can draw attention to subjects, or to portray abstract ideas. Consider the use of lines in a subject’s pose, in scenery, in styling elements, in shadow & highlight, and so on.
Thick or heavy lines might say bold or lack of subtlety, while a thin line might say refined, or even frail.
Lines can be used to frame and unify, or to divide and separate elements within an image.
Leading lines can direct the viewer’s eye through a scene to a point of interest – and they can do so with a sense of urgency with direct, straight lines, or at a relaxed pace with fluid, curved lines.
So how we use line, and in fact all the Elements of Art, determines the emotions we convey and their impact on the stories we tell.
