“Vik Muniz (born 1961) is a Brazilian born, New York based artist who experiments with media. […] In his picture of Sigmund Freud, he uses chocolate to render the image. For his Sugar Children series, Muniz went to a sugar plantation in St. Kitts to photograph children of laborers who work there. After he returned to New York, he bought some black paper and several kinds of sugar, and copied the snapshots of the children by layering the different types of sugar on the paper and photographing it. He made the images from the sugar at the plantation.” (Wikipedia)
