For many photographers, no aspect of photography is more difficult than composition. Perhaps, for that reason, people have tried to create rules for composing photographs. But the landscape Masters of the past were unanimous in their disdain for such formulas.
« To consult the rules of Composition before making a Photograph is a little like consulting the law of gravitation before going for a walk » said Weston. While rules ( maybe guidelines would be a better word… ) can be helpful in some situations, design is too complex for any rule to apply in all situations. The only one I know that always apply is Simplicity.
