thumbnail preview of photo

a Merganser duck scurries back upstream on the Merced River in the Yosemite Valley. with this fast-exposure image you can enjoy plenty of intricate detail of an avian in motion on a gently flowing river. to better reveal colors of Yosemite sky and valley mountains that the photographer believes are reflected around the wake path, select the image in a large format canvas or print.
