Filters are usually one of the photographer's weapons for creating dramatic photos. One filter that is widely used is the ND filter. This filter is often used for long exposure photographs such as waterfalls so that they look smooth, for example.

The way an ND filter works is to reduce the light entering the camera like sunglasses, more or less. So what are the advantages? By reducing the incoming light, you can use a longer shutter speed so that your photos are not over exposed or too bright. Apart from that, another advantage is that ND filters can suppress the movement of objects when photographed so that fast moving objects can look calmer.

Apart from that, another benefit is that you can use a larger aperture (small number). So your photos will get blurry even during the day, so you don't have to worry about overexposure.
