Charles Sheeler's photographs don't get exhibited nearly as often as those of his better known modernist peers, photo legends like Alfred Stieglitz and Paul Strand. Even so, Sheeler is a recognized master of 20th-century photography who brought cubist aesthetics into the realm of photographic image making. An exhibit of his work opens this week at the Georgia O'Keeffe Museum in Santa Fe. Admission is $4 for New Mexico residents with ID. The Photography of Charles Sheeler: American Modernist runs through May 1. (505) 946-1017.
