With the tide on its way out, I had a late
afternoon wander on the beach and a visit to the Lahave Islands. In complete contrast to bright warm sunshine of
earlier in the day, during my visit heavy clouds started to roll in from the
south giving perfect conditions for some long exposure experiments.
In recent months, I have been trying out Neutral
Density (ND) Filters, the purpose of a ND Filter is to reduce the amount of
light entering the lens. This allows the photographer to select combinations of
aperture, exposure time and sensor sensitivity that would otherwise produce
overexposed results.
I have not had too much success; it is taking time and a lot of patience to develop all the correct combination of camera
settings ~ progress is slow, but is also enjoyable.
Today, I thought I would try something a little
different, to put a 10-Stop ND Filter in front of my permanently in place Polarizing
Filter which I believe is a 2-Stop reduction ~ being the amateur mathematician
that I is, I can confirm this will give a 12-Stop reduction. To capture the
conditions a little better, I decided to use Black and White.
Careful observation of the results below will highlight the intended motion-blur or smoothing out in the water, but unfortunately not so much as I hoped with the clouds. All photos were done at 100ASA with the F-Stop and Exposure noted against each.
In time I hope to gain much improved results, I know spectacular photos can be achieved with ND Filters.
