Specifically made for the Phantom 3 Pro/Advance, this ND filter reduces the amount of light coming into the sensor. It gives you the freedom to create your own work by allowing more control of the camera's aperture, exposure time and sensor sensitivity settings. The ND8 filter passes through 1/8 of the incoming light. This is equal to a 3-stop filter strength.
Effectively, the ND8 filter helps to avoid overexposed photos.
