Why do we want to reduce the amount of light? That’s a question that provably most of you are thinking about, at least I made myself that question once when starting as this action can seem counterproductive as we are normally looking for as much light as possible. Let’s imagine that we are in front of a lake with a nice reflection, and the only thing that keep out of looking as a mirror are the lake waves, or in front of a waterfall and we want to get a blurry wather effect or in the coast when we want to remove the waves of the sea or even when we want to remove cars and people moving aut of the frame. Ok, so let’s imagine that our expossure values are ISO 100 f/8 (for a good image quality) and exposure value is not enough for achieving the desired effect as it is too fast and waves, people, vehicles are frozen in the image. If you close the aperture but shutter speed is still too fast, then it is time to use a ND filter that reduces enough light that allows us to increase that shutter speed to the values we want. In the picture Nº1 we can see the picture taken with no filter, in a tripod using a fast shutter speed, that’s why we can see the waves in the water but in picture Nº2 we can see the same picture using a 6 stops ND filter, a tripod and a slow shutter speed, removing waves on the water clearing the reflection.
