Neutral density filters have become indispensable in photography. Especially in landscape photography they are constantly used. You know those great pictures of flowing water that look so "fluffy" soft - for something like that you need a neutral density filter, for example. A neutral density filter or "ND filter" (neutral density filter) absorbs the light, allowing you to expose longer. It looks so amazing because of that long exposure and the movement of the water. Taking pictures with a neutral density filter obscures the incoming light and allows you to shoot better in very bright environments. In turn, using a ND filter in bright environments allows you to shoot with a larger aperture or slower shutter speeds. You can achieve beautiful effects by taking pictures with a longer exposure time. Images tend to be overexposed when you use a particularly slow shutter speed. With a gray filter you can prevent this and take pictures with a long exposure time despite a lot of light. As a result, movements blur and flow into one another. For example, you can display water or clouds as well as fast-moving objects in a particularly creative way. The K&F Concept Nano-X PRO series ND1000 filter impresses with its excellent quality, it is delivered in a stylish case (magnetic closure). Including cleaning cloth. I shot the five pictures and numbered them. The difference is obvious. The filter is worth the money, it is simply screwed on and even my lens protection still fits on it. This filter makes you want more and gets full marks from me!
