A friend of mine lent me a ND 1000 filter for my vacation in California. What this filter does is very simple: it reduces the light coming through the lens by a factor of 1000. It means, in daytime even with a bright sun, you can have an exposure of several seconds. Then, the sea and the sky are altered significantly and it is possible to convey unique ambiances. Of course, this trick has been known for a long time. I tried to play with it and you can see some examples below. The pictures were shot from North to South, from Fort Bragg to Point Reyes. The filter has a side effect as a kind of color cast, so it is important to shoot in raw format. I also tried black and white processing to enhance the contrast and the texture.
