What is beauty? It’s a question fashion photographer Rick Guidotti often asked himself during the many years he worked for clients such as Yves Saint Laurent, Elle and Harper’s Bazaar. In a moment of serendipity, Guidotti walked by a young woman with Albinism (a genetic condition that results in loss of pigmentation) at a New York City bus stop, and wondered why she wasn’t considered beautiful in his other world. This exploration resulted in a Life feature of young women with Albinism smiling out from under the headline “Redefining Beauty.” It was a watershed moment for magazines as well as for the photographer, who has spent the past fifteen years working to transform societal attitudes towards individuals living with genetic difference. Guidotti, who founded Positive Exposure, an organization which utilizes the visual arts to significantly impact the fields of genetics, mental health and human rights, will speak about the work his group does and the many important ways it has guided the conversation about the richness and beauty of human diversity.
