Diagonal lines are lines which can suggest action, stimulation and depth. The use of diagonal lines can help draw the eye through a photo. The best way to utilize diagonal lines is to present them from the bottom left of the photo to the top right, this is because our eyes naturally scan from left to right. To prevent the photo from looking split, one should try positioning your diagonal lines to begin slightly above or below the corner of the photo. Diagonal lines are supposed to indicate dynamic movement and they can also give a sense of energy. When something is in the process of falling over, it’s diagonal; a person running is diagonal; and a palm tree blowing in the winds during a Miami hurricane is diagonal. Some may consider diagonal lines to be less formal than vertical and horizontal lines, but in that sense one could say that a diagonal line is more interesting.
