The soft-edge gradient filters in this set can significantly reduce the contrast between the bright sky and the darker landscape, resulting in more balanced and natural-looking images with rich details. The Soft GND0.9 and Soft GND1.2 filters reduce exposure by three and four stops respectively, making them ideal for use in areas with varying lighting conditions. The blue & gold streak effect filters add a subtle blue or gold streak across your frame, creating a dreamy or ethereal feel for your shots with the blue streak, or capturing warm, golden lighting, creating a vintage, nostalgic feel with the gold streak. The filters are precisely CNC machined to be exclusively compatible with the DJI Mini 3/Mini 3 Pro. Made of aircraft-grade aluminum alloy, these lightweight filters won't interfere with drone calibration or balance. Made of imported HD optical glass, each filter is coated with 30 layers of NANO material on both sides, making them resistant to water, oil, scratches, dust, and fingerprints.
