Today is Blog Action Day! "Blog Action Day is an annual event that unites the world's bloggers in posting about the same issue on the same day. Our aim is to raise awareness and trigger a global discussion around an important issue that impacts us all."

The theme for 2010 is water. We figured it was a great time to offer a few simple and quick tips on taking photographs of water...

* For soft waterfall or rapid shots, put your camera on a tripod and use a long exposure. This will make the still areas in the shot not blurry from movement during a long exposure, and will give the moving water a time-lapse feel.
* To freeze moving water, such as close-up water drops, use a fast shutter speed and a flash. (How-to here)
* To capture details under the water (when standing above), use a polarizing filter. The filter will reduce or eliminate reflections on the surface.
