ButterflyPhoto 3pc Filter Kit for DJI Phantom 3 Pro, Advanced, Quadcopter 4K UHD Video Camera Drone This Must Have Accessories Bundle Includes CPL + ND4 + ND8 + Filters + Case + Lens Cleaning Pen Circular Polarizing Filter (CPL): The polarizer filter helps to reduce glare and improve color saturation. When filming from a quadcopter, a large amount of light is reflected back up towards the camera. 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. Two Neutral Density filters (ND4, ND8): 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 &quot;jello&quot; 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. The following NDs are included: ND4: This ND cuts light by 2 stops. ND8: This ND cuts light by 3 stops Lens Cleaning Pen - Removes Dust And Finger Prints Without Scratching Your Device + ButterflyPhoto Micro Fiber Cleaning Cloth This Kit Includes Some Of The Essential Accessories You Need To Take Full Advantage Of Your New DJI Phantom 3 Pro, Advanced, Quadcopter 4K UHD Video Camera Drone
