I love the ocean. I love shooting the ocean using long shutter speeds. The wave movement and sometimes spooky effect is interesting and surprising because you don't quite know what you are going to get until you review the image. Shooting these kind of images at or near sunset adds to the image because you are mixing cold and warm colors.

          Because it is fairly dark the water becomes even colder (color temperature). Yet the sky is very warm because of the setting sun. Look at this image and evaluate the difference in color temperature between the sky and the water.

Here is another one:

These images create tension between the cold and warm colors. Carefully look at the composition where I used the water to lead the viewer into the image dynamically (because it uses a curve).

          Using a small F.Stop makes for a long shutter speed needed for this kind of effect. Use the lowest ISO your camera has to help you get that long shutter speed. Lastly, if this is not enough for a long shutter speed, use a neutral density filter.

          When you can find green moss to top it off it just creates a bit more interest.
