The document discusses the work of four photographers - Jürgen Schadeberg known for photographing Nelson Mandela from 1952 onwards capturing his innocence while imprisoned for fighting apartheid; Nick Ut who won a Pulitzer Prize for his photo of Vietnamese children fleeing the Vietnam War showing the horror of war; Charlie Waite whose landscape photo of a lavender field in France leads the eye to an isolated tree using color contrast; and Katerina Plotnikova whose surreal photos juxtapose powerful animals with delicate models using shallow depth of field to controversial yet sensual effect.
