Caruba DJI Inspire + DJI OSMO PL/ND-Filter Set This Caruba DJI Inspire PL / ND Filter Set contains three filters that can ensure that the recordings you make with your DJI Inspire quadcopter become even more beautiful. The set consists of a polarization filter, a two-stop gray filter and a four-stop gray filter. The polarization filter reduces reflections from water or reflective surfaces such as windows and also optimizes contrast and colors. The gray filters do not affect the color, but the amount of light that penetrates the sensor of the camera. Ideal for shooting in bright conditions such as along the waterline or in the snow. Highlights become less harsh. The filters are lightweight but are made of high quality materials.
