Why do you need Drone Filters?
On older drones, such as the Phantom 3 and 4, the aperture is locked at F 2.8, meaning that the only way to successfully obtain proper exposure is to increase your shutter speed. This increase in shutter speed, will often time result in what is known as the “jello effect”, or to simply put it, shaky footage. Depending on the angle you are filming at, your camera may even pick up the edge of your propeller blades, leaving you with an obstructed view and choppy footage.
Newer drones, such as the Phantom 4 PRO and Phantom 4 Advanced, give operators the ability to manually adjust aperture settings, allowing for an enhanced cinematic look. While these exciting new opportunities for filming at a slower shutter speed broaden one’s potential for image capture, they can also present the challenge of maintaining proper light balance. In order to help combat this potential overexposure of light, a Neutral Density filter can now be placed and regularly used on one’s drone camera.
By using a Neutral Density Filter, a certain amount of light will be blocked from reaching your sensor. By limiting the amount of light that comes in contact with the sensor, you will be able to film at slower shutter speeds, and a lower aperture, helping you to successfully achieve a cinematic look.
