Rather than thinking of images in terms of static balance, dynamic balance or imbalance, a different conceptual approach can be used to arrange elements in a way which energises the eye and leads it from the centre of the frame outwards.
Dynamic tension makes use of the energy inherent in structures; and compositionally locates them in positions where their energies pull or vector away from each other, most potently in highly contrasting directions. The achievement of dynamic tension is straightforward - the challenge, however, is to use it in a manner which does comes across as natural and with enduring appeal.
Images based on dynamic tension commonly incorporate a variety of contrasting diagonals; counter-lines, curving or straight; and vectors, real or implied. Overarching self-stabilising or enclosing structures, such as ellipses, are generally avoided as they resolve tension within the image.
