Dynamic tension is a way of using the energy and movement available in various features of the frame to draw the eye out of the picture, in contrasting directions.

The ideal combination is a variety of diagonals in different directions, opposed lines and any structural device that leads the eye outward, preferebly in competing directions. Incorporating triangles and diagonals together into the images can help to create visually a certain level of tension, since they subconsciously suggest instability. Triangles can be actual triangle-shaped objects or implied triangles.

This is essentially making use of the energy inherent in various structures, and using it to keep the eye alert and moving outwardfrom the center of the picture.
