Harmony is an elusive, perhaps even ineffable aspect of photographic images. So is disharmony, its possibly disturbing, but often stimulating opposite. Although many photographers share the view that the communicative impact of images is enhanced by their harmony, there are countless individual artistic interpretations of what makes an image harmonious or disharmonious. Some consider harmony primarily as a visual compositional feature of photographs, also allowing for the unusual, for the unexpected, or even for the disturbing when it comes to compositional harmony or disharmony. For many others, harmony is also a thematic concept, and they find harmonious elements in the communicative content of the image, arising from the various interactions depicted in the photograph. The intentional lack of harmony may also lead to most creative photographic compositions. All photographic genres use the elements of composition to create the sense of harmony or its opposite.
