Silky smooth water
Want to get that really silky smooth water when you take pictures of waterfalls?
The trick is to keep the shutter open as long as possible. The problem is how to do this in bright sunlight. what you need is called a neutral density filter. What this does is lowers the amount of light getting to the sensor. It’s really just a dark piece of glass that screws on to the end of your lens. By reducing the amount of light, the shutter can stay open longer. As you know, the longer the shutter is open the more the things that move will blur. So if you set your camera on a tripod, it can’t move, hopefully the only thing moving is the waterfall. This is what allows the water to blur and become silky and smooth. Here is an image I shoot using a ND Filter.
