I actually had a circular polarising filter with me but it was getting a bit too dark to use it. The reflections on the surface were the fountain lights, which had just turned on. I had to slow down the shutter for this as it was, any slower and the waves of the water would have blurred too much. I have used the filter for sky shots but have yet to use it in a water shot... Now I want to shoot more water.. Thank for the comments.

Even if you choose not to choose, you still have made a choice
