As is I suppose well known, the waterfalls in Iceland are superb, and seem to have a character of their own. They are not like waterfalls I have seen anywhere else, although it is a little hard for me to put my finger on the difference.
We spent a happy day in the Highlands that included photographing several waterfalls. This image shows a portion of the one named Haifoss. I used a +4 neutral density filter and exposure-duration bracketing to create the dramatic effect in this photo.
