I think our compositions and use of color depends of our luck in street. I am not talking about studio photographers. We can be more intelligent.
We can add our photographs more politics , more social science , politics or say anthropology.
Soviet Cinematographer Eisenstein was strongly believing this and he was saying we must hit to the enemy with our images , colors , compositions. In his time enemy was not america but germany. He was defending put two different images in movie stream and these totally different images would create a meaning. Soldiers fires to civils and cows being slaughtered . He defends the same for color , these two images would pure red.
