LINES

Vertical Lines:
The vertical line is like a tree, tall and balanced, solid and firm. It presses against the sky, even gravity pulls it downward. As such, the vertical line symbolizes strength, power, and stability.

Horizontal Lines: Peaceful and static, the horizontal line suggests stability, permanence, and tranquility. This may explain why gazing at the horizon, at horizontal line that occurs where the earth meets the sky, is inherently soothing.

Generally, objects closer to the horizon line appear to the viewer to be more distant, and objects that are further away from the horizon appear to the viewer to be closer.
When horizon line is low in the frame, the emphasis is on the upper portion of the image, yielding a more expansive look. When the horizon line is high in the frame, what is below it takes on more meaning.

Diagonal Lines: Diagonal lines are active and dynamic. They create tension and bring to mind action and motion. Diagonal lines can create a sense of perspective in a scene.

Zigzag Lines: These lines start, stop and change direction in a jerky fashion. Erratic, active, and imbued with tension and energy, zigzag lines evoke a sense of anxiety.

Curved Lines: They show motion, but slower motion than diagonal lines.

S-Curve: The S-curve line shows repetitive motion that is gentle with a sense of distance. These curves usually are shown on roads.
