Apocalypse Now - 1

There is just one source of light in this image, the golden light of the sun.The time of the day is sunset.The character in front is lit from the left , and the amount of light is just enough to discern the features of his face.The character in the background has more light shining on him and reveals the gun he is carrying in his hand.The absense of any fill light helps portray the gravity of the shot and reinforce the theme of the movie, which is war.
