During his career, his work was published in many American magazines, including Esquire, New York, Travel + Leisure, Seventeen, Time, Newsweek, Harper's Bazaar, McCall's and Woman's Day.
Serving in the US Army Air Force during World War II, Wynn learned how to take pictures and run a photo lab and, back in Los Angeles after the war, he attended the Art Center School: while still a student, there he won the Condé Nast Photo Contest.
He went on to shoot major accounts for top advertising agencies including Revlon (with Kay Daly[1]) and memorable campaigns for clients as diverse as International Paper, Van Raalte and Maidenform (the famous "I dreamed I was ... in my Maidenform bra" [1]), and Ford cars, while continuing his photojournalist work covering events such as Le Mans auto racing [2].
Wynn's portraiture and photo essays included entertainers (Jimmy Durante, Dolly Parton), artists (Salvador Dalí) musicians (Duke Ellington, Luciano Pavarotti, Louis Armstrong), television personalities (Carol Burnett, Sid Caesar), movie stars (Robert De Niro, Katharine Hepburn, Dustin Hoffman, Al Pacino), film directors, (Alfred Hitchcock, Billy Wilder, Frank Capra, François Truffaut), fashion models (Suzy Parker and Jane Fonda in the early days of her career) and such national figures as president and Mrs. Lyndon Johnson, Rose Kennedy, Norman Mailer, Gloria Steinem and the very young Bill Gates (for a Newsweek cover).
Wynn's editorial spreads of beautiful people and places in international cities, pubs, vineyards, and restaurants brought him into contact with food writer James Beard.
