Figure 16-19 Blurred snow and water. Water is the most popular subject for blurred motion,
which in this case is emphasized by the sharp outlines of the tree in the foreground and the
rock formations in the back. A slow shutter speed of ¼ second made the falling snow the
important part of the image. The diagonal streaks of the snowfl akes framed against a dark
background area enhance the feeling of a blizzard. (Photos by Ernst Wildi.)
Figure 16-20 Blurred motion. Slow shutter speeds can enhance pictures of ordinary subjects
such as leaves moving in the wind (left) and the steam coming from the geysers in
Yellowstone (right). Such images are usually most effective if they include sharp elements
such as the tree trunks of the trees or the rocks in Yellowstone. (Photos by Ernst Wildi.)
