One of my favorite aspects of photography is its capacity to see in ways that our eyes cannot — to show us things we could not see when we were there with the camera. Long exposures are a classic example of this. During a recent family outing to Berkeley Tuolumne Camp, just west of Yosemite, I explored the rocks and riffles of the South Fork Tuolumne River. CLICK HERE for some images of motion-blured water. The first few are from the South Fork Tuolumne; the rest are from other excursions around California.
