In the visual arts – in particular painting, graphic design, photography and sculpture – composition is the placement or arrangement of visual elements or ingredients in a work of art or a photograph, as distinct from the subject of a work. It can also be thought of as the organization of the elements of art according to the principles of art.
Expert and Maestro says
 Consulting the rules of composition before taking a photograph, is like consulting the laws of gravity before going for a walk. [Edward Weston]
 The so-called rules of photographic composition are, in my opinion, invalid, irrelevant and immaterial [Ansel Adams]
