Doing research on Cambodia now, need to know more before making possible portraits in the country at some future date. Am currently reading a very good book by Nic Dunlop called "The Lost Executioner" The story deals with the history of Cambodia under the Khmer Rouge and the search for the leader comrade Duch who led the infamous Khmer Rouge torture, execution center of Tuol Sleng in Phnom Pehn between 1975 and 1979. Over 20 000 people went into the prison and only 7 came out alive. These photographs were taken of the prisoners sometime before they were tortured and executed, the photographers name is Nhem En.
