WASHINGTON (AP).- Photographer Annie Leibovitz says she has come back from some dark days and revived her creativity with a new project now on view at the Smithsonian American Art Museum that marks a departure from her popular celebrity portraits. Two years ago, Leibovitz was facing millions in debt and a mismanaged fortune that nearly cost her the legal rights to her own work, which includes some of pop culture’s most memorable images. The ordeal was a good lesson in managing her business, Leibovitz said, but left her “emotionally and mentally depleted.” On Tuesday, she led a tour through the photographs she says renewed her inspiration with a few road trips through U.S. history. The idea grew out of a book she had wanted to make with her partner, Susan Sontag, with a list of destinations and an excuse to visit them. After Sontag died, she eventually revived the idea with her young children. It
