Platon has made over 20 Time magazine covers with his portraits of people like Donald Trump, Bill Clinton, Barack Obama, George Clooney, Silvio Berlusconi, Mohammed Ali, Adele and Sinead O'Connor. But he has also photographed people who are the opposite of famous and powerful - and recently published a book called The Defenders: Heroes of the Global Fight for Human Rights - which contains work done over 15 years around the world telling the stories of refugees and other oppressed people. He tells us what makes a true leader, and how the meaning of a photograph can change over time, and depending on who is looking at it.
