What is an ND filter?
An ND filter reduces the amount of light that arrives in the sensor.
The higher the number behind the “”ND””, the stronger the darkening.

Why do you need an ND filter?
In order to be able to create a liquid video, the exposure time should
They double the frame frequency (pictures pro-Second).
If you take a video with 24 pictures pro-Second, you would get an optimal exposure time of 1/50s.
To achieve this, the sensor must be darkened, otherwise, the video would be overexposed.

How strong must the filter be?
The height of the required decay varies depending on the brightness:
Nd4 & ND8: dusk to heavily cloudy weather
ND16: cloudy to slightly cloudy weather
ND32: sunny weather
