This custom ND filter set for the DJI Mavic 3 consists of ND64, ND128, ND256, and ND512 filters.
By implementing these with your drone's gimbal camera, you can get creative with the colour contrast and overall aesthetics of your shots.
They work by reducing the amount of light coming into the sensor - granting you more control over the camera's aperture, exposure time, and sensitivity settings.
