 Kasraian's aim is to depict the entire ethnological diversity of Iran, an endeavor generally applauded by Iranian population but not uncontroversial amongst more conservative elements of Iranian society.Kasraian cites the publication of his photobook "L'iran rurale" by the renowned French publisher "Doublepage" as a turning point in his career.A further milestone was the publication of "The nomadic people of Iran" by Richard Tapper and Jon Thompson with hundreds of photos by Kasraian , whose work has stimulated some of the essays on the tribal peoples of Iran by a dozen anthropologists in the book.
