Night

This photo is a good representation of night because the ones who didn't know anything about the concentration camps were living in the light and hadn't experieced what total darkness was: a world without hope, faith and the goodness of people. Everything bad that happens to Eli during the Holocaust happens during the Night. In the bible when God created the heavens, the earth was in darkness, which is a symbol of a world without God. Eli questions whether God even exists when he can let such awful things happen. Night is also a metamorphosis of how Eli's thoughts turn evil in the novel ( a darkness of the soul). The reality of night to Wiesel meant the silence of apathy, the wordlessness of the bystanders who knew the truth of Hitler's death camps, but who took no action, and made no objection to the Nazi's extermination plan.
