NPR's "Fresh Air With Terry Gross has a terrific interview with Timothy Greenfield-Sanders, and super models Beverly Johnson and Carol Alt on the above mentioned NPR show tonight. Here is the link: http://www.npr.org/2012/07/30/157590245/getting-old-is-hard-even-and-especially-for-models
They were plugging the HBO documentary directed by Greenfield-Sanders: "About Face: The Supermodels Then and Now."
Beverly Johnson was very articulate about the difficulties of being a black model at a time when high-end fashion and advertising photographers did not know how to light black people; stylists didn't knowwhat to do with their hair; makeup artists didn't know what to do with their skin; and Kodak films had difficulty with non-caucasian skin tones (According to Greenfield-Sanders most photographers still don't know how to light for black skin or expose for it either)
Both Alt & Johnson are good on how short a top model's career is, and Terry Gross asks good questions aboutbeing photogrpahed and Greenfield-Sanders has good short answers.
