With the DJI ND Filter Set for Mavic Air, you can achieve cinematic imagery by reducing the light hitting your Mavic Air's camera sensor. The included ND4, ND8, and ND16 filters reduce the light by 2, 3, and 4 stops, respectively. By reducing the light hitting the sensor, you can achieve more cinematic motion blur by increasing the shutter duration to compensate for the light loss.
