K&F DIJ AIR 3S filter (CPL)HD, single-sided anti-reflection green film, waterproof and scratch-resis

Nano-X — polarising filter, cuts reflections and deepens colour.

A polarising filter takes the glare off water, glass and foliage, and with it brings out the colours that were hiding underneath. The sky darkens, clouds stand out, leaves stop flaring white and you can see through the surface of water. The effect is set by rotating the filter and is strongest at right angles to the sun; it cannot be recreated in post, because it is a property of the light rather than a colour in the file.

The filter is built for the DJI Air 3S drone: thin enough to close the original gimbal guard over it and light enough not to load the stabiliser.
