Use a Neutral Density Filter and Sturdy Support for Creative Long Exposures

Why would you put a dark filter over your camera lens to let in less light? It can make autofocus difficult, complicates exposure calculation and makes hand holding the camera impossible because of the long exposures required. So why do it–to let the camera record subject motion over time. Long exposure photography records movement in a photograph and the results can be artistic and pleasing if done properly.

Take Care Using ND Filters

A neutral density filter may compromise the point-and-shoot convenience of today’s automatic cameras. Because it cuts the light by as much at ten stops it is best to first compose and turn off auto focus before mounting the filter especially when viewing through the lens on a DSLR.

Exposure calculation can be complex, but a modern DSLR or mirrorless camera will usually calculate exposures accurately up to thirty seconds. Set the ISO to the lowest setting and use a narrow aperture (f11 or f16). The camera monitor will usually give a fairly accurate representation of exposure. Begin with a test shot and adjust the settings as necessary.

Choose the Appropriate Subject

Flowing water, clouds and people in motion are subjects that can benefit from long exposure photography. Waterfalls and ocean waves make excellent long exposure subjects when done properly. Experiment with exposures of one to five seconds for waterfalls and streams and decide what gives you the most pleasing effect.

Longer exposures of ocean waves can turn the water into a smooth, flat almost surreal representation that stretches the bounds of reality. Done right, the results can be very artistic. The same goes for clouds which can turn the sky into soft, billowy streaks.

People in motion can also work for long exposures. People in a crowded square or busy intersection become streaks of color and interesting shapes. Given enough time, people can vanish completely, giving the scene a deserted look.

Mirrorless camera on HandlePod with ND filter for long daylight exposure.

Using a neutral density filter to increase exposure time in daylight to several seconds eliminates the possibility of hand holding the camera. Use a tripod or other sturdy alternative support to keep the camera steady during long exposures. HandlePod is a light weight, pocket size support that can be used effectively with ND filters for daylight long exposures described in this article by Mirrorlessons. A neutral density filter and sturdy camera support opens up a new realm of photographic creativity.
