Here we are, last month of another year.
Back in September I purchased two Lee neutral density filters. The 10 stop Big Stopper, and the 6 stop Little Stopper.
These filters do one thing and that is to reduce the amount of light entering the camera lens.
So why would you want to do this?
Reducing the amount of light forces a change to iso setting, or shutter speed. The less light, the longer the exposure time.
Moving objects start to blur in longer exposures. This makes moving water look creamy. Think waterfalls and cascades.
The two images shown here were taken moments apart.
The top one was shot a 15 second exposure at f/16, iso 100. I used the Big Stopper.
The lower one was a 1/4 second exposure at f/22, iso 100.
When I saw the two images side by side like this, the difference in visual focus jumped out at me.
The upper, 15 second exposure, lets my eye rest on the ocean for a moment before guiding my view into the Jetty.
Contrast that with the relatively short 1/4 second exposure of the lower image. My eye skips from breaker to breaker. The Jetty is almost totally obscured. It is definitely not a major element of the composition.
My take away is that you can use a long exposure to redirect the eye of the viewer away from a busy, noisy subject to a more preferred one.
What do you think?
By the way, you are looking at the South Jetty at the mouth of The Columbia River. today was relatively calm. Don’t think I would want to be on the observation platform during A real storm.
