Gray filters are indispensable in photography. They are used all the time, especially in landscape photography. You know those great pictures with flowing water that looks so “fluffy” and soft – for something like that you need a gray filter, for example.

A gray filter, or “ND filter” (neutral density filter), absorbs the light so that you can expose for longer. This long exposure and the movement of the water make it look so great.
Taking photos with a gray filter darkens the incident light and makes it easier to take photos in very bright environments.
If you use a gray filter in bright surroundings, you can take photos with a wider aperture or longer exposure times.
You can achieve beautiful effects by taking photos with a longer exposure time.
Usually, images are overexposed if you choose a particularly long exposure time.
You can prevent this with a gray filter and take photos with a long exposure time despite a lot of light.
As a result, movements become blurred and merge into one another.
For example, you can depict bodies of water or clouds, as well as fast-moving objects, particularly creatively.

I took five pictures and numbered them. The difference is clear to see.
The filter is worth the money, it is simply screwed on and my lens protector even fits on it.
