Tiffen 58mm Neutral Density 0.9 Filter

Rating:
Summary: Sunglasses for your camera
Review: Ever seen those photos of rivers and waterfalls where the water is all blurred and misty? This filter can help you achieve that and other effects. It drastically cuts down the light passing through your lens, forcing slower shutter speeds that will give the blur effect.

This is the strongest ND filter, you may want to look at the 0.6 or 0.3 for a less noticable effect. Also, be prepared to use a tripod. This filter will easily push your shutter speed into multiple seconds, so you'd have to have one.
