Using Lines 8 . Our eyes tend to travel along these lines as they move from one part of the frame to another. When used in this way lines are referred to as leading lines because they are selected or arranged to lead the viewer's eyes into the frame, generally to the scene's center of interest. In addition to moving our eyes around the frame, lines can suggest meaning in themselves. Straight, vertical lines suggest dignity, strength, power, formality, height and restriction.
Horizontal lines suggest stability and openness.
