Where is the reference to the gray filter?
Because not every photographer can take their photos in the studio and adjust the light in a targeted manner. As soon as you want to take pictures in bright sunshine, but you need a wide open aperture for reasons of the desired composition, most cameras quickly reach their limits with an exposure time of 1/4000 seconds, despite an ISO setting of 100. In order not to overexpose the image, the aperture would have to be closed even further, which would then destroy the planned image look.
And this is exactly where the gray or ND filter is used in photography. Another purpose can be found in long-term exposures. Here, too, the effects and properties of the neutral density filter can be used to significantly increase the exposure time.

How does an ND filter work?
In principle, a gray filter is comparable to sunglasses only for cameras and reduces the light entering the lens and the sensor. This reduces the amount of incident light and the resulting exposure time is increased by a fixed factor. Gray filters are available in different strengths and shapes, with which a wide variety of exposure times can be realized. The reduction in light incidence ranges from 3 f-stops with bright ND8 filters to 10 f-stops with the darkest ND1000 filters. On the one hand, we offer you round filters that can be screwed on or attached magnetically, or plug-in filter systems including filter holders.
