A native New Yorker, Hartman was one of the few female Photographers who captured the celebrants of Studio 54, the most famous club in the world. She was one of the very early photographers taking her camera where nobody else wanted to: backstage at fashion shows where the real excitement was. 

Her keen eye offered unprecedented visual entree to the creative personalities who transformed New York into the most fascinating city in the world. 

Her first glitz assignment was the 1976 wedding of Hemingway's granddaughter. Hartman's coverage was published on the cover of the Daily News Record; a prominent fashion publication.

For the past four decades, Hartman has photographed fashion and celebrity icons in some of the most legendary settings of New York nightlife, from Studio 54 to the Metropolitan Museum’s Costume Institute Gala. 

Hartman's work appears in The New York Times, London Sunday Times, Vanity Fair, Vogue (US, French, Dutch, and Italian), New York Magazine, Marie Claire, Allure, Elle Magazine,, Grazia, Le Journal de la Photographie, Colette, The Daily Beast, W, Rolling Stone, among many other international publications including books. In November 2000, Hartman’s solo exhibit “incomparable women of Style” ran for 3 months at Fashion Institue of Technology.

Her photographs are in the collections of Saks Fifth Avenue, the Patterson Museum, Ralph Rucci, Jerry Hall, Jane Holzer, Bianca Jagger, Patrick McMullan, Mary McFadden, Jean Shafiroff, and Paul Wilmot and many more.
