Roaring Mountain Stream

When I go to the mountains I always try to visit where water flows. As a kid growing up in the Southern Appalachians summer always meant spending time playing in mountain streams that could chill you to the bone, a wonderful feeling during the dog days of August. To get the right angle for this image a had to jam a tripod against the guard rail of a bridge and hope a car didn't come along. I had to move off this narrow one lane bridge twice because of cars before I was able to capture this 15 second exposure. Notice in order to capture the movement of the water an exposure of 1/15 of a second or slower works well. The slower the shutter speed the smoother the moving water becomes. A very long exposure can cause the moving water to start looking like fog. Weird! lynnfreeny.com
