This 3-Pack of Graduated Filters from Freewell lets you achieve dramatic and creative effects when shooting with your Autel Robotics X-Star or X-Star Premium quadcopter. The kit includes 3 different graduated lens filters: gray, orange, and blue. Each of the filters features a colored half that adds color to a portion of the image, while the clear half maintains a neutral color balance. The gray filter is intended for light reduction in skylines of landscape shots. The orange filter should be used during normal evenings to color the sky. The blue filter crates a realistic cooling effect that enhances the blues of water and sky. In addition to the filters, a traveling case and cleaner are also included.
