Setting limits or parameters within which to work enables a concentration of energies. Even within set limits the infinite variety of possible images can be overwhelming. Though the work may be intensely personal it may also resonate in a more universal way. What is essentially a two dimensional flat plane covered with colour, line, shapes and textures may become another means of communication. A line or shape may suggest motion or kinetic energy. A flat solid area of colour may be used as contrast to anchor a composition. A colour may evoke certain emotions. It forms a sort of visual vocabulary.
