This is sunset at Seljalandsfoss waterfall in southern Iceland. When shooting falling water, there are two choices: use a fast shutter speed to show the detail in the form of the water, or use a slow shutter to purposely blur the water to create an artistic interpretation of it. Of course, we never see blurred water with our eyes, so this is an artificial, photographic construct. For this picture, I used a relatively fast shutter of 1/320. One of the things that fascinate me about massive amounts of falling water is the intriguing shapes and designs in the water that you can only see for an instant -- unless a fast shutter freezes it forever. My other settings for this image were f/11 and 200 ISO. I captured the waterfall with a 24-105mm lens.
