Diagonals Horizontal lines lend a static, calm feel to a picture, while vertical ones often suggest permanence and stability. To introduce a feeling of drama, movement or uncertainty, look for diagonal lines instead. You can need nothing more than a shift in position or focal length to get them - wider angles of view tend to introduce diagonal lines because of the increased perspective; with wide-angle lenses you're more likely to tilt the camera up or down to get more of a scene in.
