{ FILTER SET FOR DJI } DJI Phantom 4 - Phantom 3 Professional, Advanced Quadcopter. Filter Kit Includes: Polarizer + Neutral Density ND8 & ND4 Filters POLARIZING FILTER: Helps to reduce glare and improve color saturation. THE POLARIZER: Reduces the amount of glare bouncing off the ground. It can also be used to slow down the camera's shutter speed by reducing light by 1.6 stops. THE ND FILTERS: ND4 Cuts light by 2 stops. ND8 Cuts light by 3 stops. THE ND: filters reduces light hitting the sensor, which slows down the camera's shutter speed. This creates a more natural-looking motion blur that smoothes out footage and helps reduce the appearance of "jello" effects from the camera's rolling shutter. They can also be used for reducing lens flare while shooting into the sun and for toning down highlights while filming outdoors.
