I was searching for ideal subjects and I struggled to find a good one\u00a0when I ran across a dead\u00a0tree on the beach along the Honoapiilani Highway\u00a0close to Lahaina. In addition to having an interesting subject, I wanted to\u00a0extend the exposure long enough to have a smooth surf but not blur my subject. \u00a0This is a tricky situation as long exposures tend to make moving\u00a0objects blurry (e.g. trees, people, plants, etc.). \u00a0So, trying to find stationary objects next to a surf was a\u00a0challenge.<\/p>\n<p>Why use ND filters you ask? Well, I&#8217;m glad you did.\u00a0The purpose of an ND filter is to reduce the amount of light entering the lens. Doing so allows us\u00a0to select combinations of aperture, exposure time and ISO\u00a0which would otherwise produce overexposed images. This is done to mostly to achieve motion blur of a subject in a wider range of situations and conditions. It&#8217;s especially useful in situations involving water.\u00a0For example, one might wish to photograph a waterfall at a slow shutter speed to create a deliberate motion blur effect. On a very bright day, there might be so much light that even at minimum film speed and a minimum aperture would let in too much light and the photo would be overexposed. In this situation, applying an appropriate ND filter will\u00a0allow for the slower shutter speed and enable the desired motion-blur effect.<\/p>\n<figure id=\"attachment_4979\" aria-describedby=\"caption-attachment-4979\" style=\"width: 1500px\" class=\"wp-caption aligncenter\"><a href=\"http:\/\/tkahler.com\/blog\/wp-content\/uploads\/2015\/11\/20150427-Maui-Beach-Long-Exposures-001.jpg\"><img fetchpriority=\"high\" decoding=\"async\" data-attachment-id=\"4979\" data-permalink=\"https:\/\/tkahler.com\/blog\/2015\/11\/smooth-surf\/attachment\/4979\/\" data-orig-file=\"https:\/\/tkahler.com\/blog\/wp-content\/uploads\/2015\/11\/20150427-Maui-Beach-Long-Exposures-001.jpg\" data-orig-size=\"1500,1125\" data-comments-opened=\"1\" data-image-meta=\"{&quot;aperture&quot;:&quot;16&quot;,&quot;credit&quot;:&quot;Terry B.
