Mario Testino is such an iconic and legendary photographer by now that it's hard to believe he grew up wanting to be a priest, or that he dyed his hair pink to get noticed when he did realize he wanted to be a photographer. He's shot an overwhelming number of celebrities and cultural icons, from Diana, the Princess of Wales to Emma Watson, Cameron Diaz, Gwyneth Paltrow, Julia Roberts, Kristen Stewart, Gisele Bündchen, and Lady Gaga. He and stylist Carine Roitfeld are credited with reviving Gucci in the mid-90s with their groundbreaking, provocative ad campaigns. He's continued to shoot for nearly every magazine, in addition to Burberry, Gucci, Versace, Calvin Klein, Dolce & Gabbana, Salvatore Ferragamo, Estee Launder, Michael Kors, and more. He continues to receive royal commissions, and in 2002 had a massively successful show at The National Portrait Gallery in London titled Portraits, which went on to tour in other cities internationally.
