Long Exposure Photography
Photographing for extended periods of time can add a whole different dimension to your photography. I consider any exposure over ten seconds to be in the long exposure category. When you have the shutter open for an extended time you begin to record movement which can lead to unique captures of time. Clouds blur through a scene. Light also renders a slightly different dimension on still objects. We all have seen the results of water captured over time.
There are occasions when even with a small aperture and low ISO we can’t get the time we would like to try these creative looks. Enter the neutral density filter. With one or more neutral density filters the creative possibilities are extended. I’m working with Tiffen ND filters (landscape/seascape kit) ** and trying the extremely dark filters. I have a three stop and a ten stop filter. These can be stacked for even more density if necessary.
Here are a couple images made with the ten stop filter in place. It is almost impossible to see through a filter this dark so my process is to pull focus and take note of the exposure reading without the filter attached. Then place the filter on the camera. In this case, the exposure was between two and four minutes. My camera will only go to sixty seconds. It also has a bulb setting but that would mean touching the camera to activate and deactivate the shutter. There’s a better way.
If you haven’t heard of the Pluto Trigger *** and its app you are missing out on many possible controls that can be added to your camera. As long as you have a remote port on your camera it can work for you. For this example, there is a conversion table for the extended time needed for long exposure ND photography. The trigger asks what the shutter speed is for an exposure without the ND filter in place. You input the shutter speed and let the app know what ND filter(s) you add and it calculates the proper exposure. Push the button on the app and the camera shutter is opened for the needed duration and then closed. Very cool!
