There is that part of the evening that’s called The Blue Hour. Colours are magical and the light is perfect. But it also presents a problem. It’s still too bright to shoot long exposures in order to blur water or clouds (or anything moving for that matter). You have to bump up the aperture which can cause problems depending on the lens your using. I don’t often shoot above f8 on my DSLR, sometimes f11 (which I guess I should do more often).

The following was a 2.5 second shot at f8, when it was still pretty bright out. I was able to blur the water enough, but was hoping for more.
