My research has uncovered nude photography of university student models in California who posed for hardly anything in return for free photos of themselves in clothes. Another item that I came across was a 13-year study conducted by academics at Columbia University in New York City. Women at Harvard, the University of Iowa, the University of Chicago and Columbia were photographed nude, in front and profile, for a study in which individual behavior was studied in relation to one's physique. Another college student had posed for naked photos for a Miami photographer, only to have the pictures published in Genesis Magazine some years later.
