Photography is at its best describing things, showing us how a camera sees at a given moment in time. That is its essence, its strength. It is not painting, nor film, nor literature. It is unique in its ability to communicate across all boundaries. The truthfulness to the subject should be expected in photography. Without that, photography loses its "reason to be". These principles form a framework and discipline to work effectively. It keeps photography simple, while still allowing for endless possibilities that can drive one to see and photograph the world.
