SHUTTER SPEED
For smooth, natural-looking motion In video filming, it's critical to keep the shutter speed set to frame rate, that is, to keep it equal to twice the frame rate for optimal results. This is because, unlike still photography, an excessively fast shutter speed can create a discordant effect and produce secondary images that will not look good in the final video.
As you can see from the image below, unlike the still image, the video clip is composed of a sequence of still images. With a low shutter speed, each still image will look blurry, but it will look smooth in the video sequence. Conversely, a higher shutter speed will capture the solid, crisp object, but once in a video sequence, all objects will appear separately, creating a discordant and unnatural-looking motion.

By using IRND filters, the shutter speed can be adjusted to the proper value to get the natural and smooth-looking motion requested in video shots, as shown in the image below.

For optimal exposure
Drones are mainly used outdoors during the day, in bright environments. As DJI MAVIC AIR is equipped with a camera module that has a fixed aperture of F2.8, and the ISO setting must be set to the minimum level of ISO100 for image quality, IRND filters are recommended as an ad-on accessory needed to control the shutter speed and achieve optimal exposure.
The image below shows the difference between an overexposed video footage and a video shot with the proper shutter speed setting during a sunny day in a snowy mountainous area.

PRECISE NEUTRALITY

High-quality IRND filters are required to be extremely neutral and accurate to prevent color change or IR contamination from affecting the final image.
The exact neutrality of the filters KENKO IRND is achieved by adopting Accu-ND technology, developed exclusively for DSLR chamber filters. Accu-ND technology provides a constant and adjusted light density over a wide spectrum range, including the infrared area (400nm-1000nm).

JUST-FIT FRAME and SCREW TYPE MOUNT

KIT 4 in 1 in CASE OF PROTECTION AGAINST TIME
KENKO Advanced Drone Filters IRND KIT contains 4 filters of different density to choose from depending on the light conditions at the shooting site. Choosing the correct density value will allow fine adjustments of the camera settings according to the different light conditions, thus avoiding diffraction and optimal exposure of the image.

In addition, for better and convenient use in outdoor environments, the KENKO Advanced Filters IRND kit comes inside an all-weather housing that will hold the filters together and protect them from moisture and dust, rain or snow.

RESISTANT
The multilayer anti-reflective coating of the filters KENKO IRND is mixed with a water-repellent layer. This ensures protection against fingerprints, stains and dust, making the filters easy to clean and maintain in ready-to-use condition.
