The prizes of a new exhibition at the Georgia O’Keeffe Museum are a pair of photographs of the artist at the easel, an aspect of her life and work that she rarely permitted photographers to capture. “My greatest desire for acquiring the collection and still my favorite photographs are two that show O’Keeffe in the act of painting,” said Carolyn Kastner, curator of "New Photography Acquisitions." “There is one each by Ansel Adams and Alfred Stieglitz, which are the only photographers she allowed to show her at work.” The exhibition, which opened on Friday, March 27, offers a selection from the museum’s collection of more than 2,000 photographs, including the newest acquisitions.
