H armony and flow The subject should look perfectly at home within its setting. The environment and all subordinate elements should be in harmony with the theme of your photograph. Harmony refers to the sense of order among compositional elements so that each contributes to the message. Including elements that are not harmonious muddles that message. The goal is to engage viewers with precise control over the sequence in which the viewer's eye explores the image. Anything that interrupts this flow could lose your audience--the viewer looks away.
