But free spirits cultivate their ­images, too. O’Keeffe owed much to the curatorial ministrations of Alfred Stieglitz, the pioneering photographer and art dealer. His gallery at 291 Fifth Avenue was one of those now-hallowed New York spaces where modernism took root in this country. O’Keeffe married him in 1924, by which time he had already exhibited her work and enshrined her as his model and muse. He took hundreds of photographs of her, sensuously infatuated images of her splayed fingers and her white neck and her handsome, wicked-witch-like face.  
The first thing one notices about “My Faraway One: Selected Letters of Georgia O’Keeffe and Alfred Stieglitz: Volume I, 1915-1933” is its elephantine bulk. Running to more than 800 extra-large, text-crammed pages, it inherently raises the question of whether O’Keeffe is a sturdy enough talent to support such heavy, reverential treatment. She was, to this viewer, an original painter, but the distilled lushness of her early scenes of flowers and skies eventually ossified, and her work became formulaic, one of the first brands in American art. She claimed to have found her inspiration in nature, but her paintings — with their radical simplification of form and near abstractness — perhaps owe more to the early experiments in close-up photography of Paul Strand, who was part of the Stieglitz circle and a close friend of hers.
