In landscape photography, water (be it the sea, streams, lakes or waterfalls) always adds an extra beautiful aspect to the scene you’re photographing. This neat technique will help you take your water photos up a notch.
A bit of theory!
One way of enhancing landscape scenes with water running through them is to use a technique called water smoothing. Water smoothing does exactly what it sounds like: it gives the appearance of smooth, flowing water.
Water smoothing relies on motion blur – typically something photographers do our best to avoid – to create the smooth water effect. The long exposure allows the movement of the water to blur, and as the exposure time increases, the amount of blur that occurs also increases. The longer the exposure, the smoother your water is going to look.
There are some issues when it comes to trying to use this effect, especially during the day. Even at the smallest aperture and lowest ISO available, it’s often impossible to get a slow enough shutter speed to give you enough blur – at least without an ND filter, that is.
An ND (Neutral Density) filter allows you to cut down on the amount of light entering the camera, simply by placing a filter on the lens. ND filters are simply a gray filter that cuts stops some light entering the lens without affecting the colour. You’ll find a whole tutorial on using ND filters here. When water smoothing, you’ll want to use the strongest ND filter you have available as this will give you the longest possible exposure time.
