Description

Exclusively designed for DJI Mavic Air, the Advanced Drone Filters IRND kit incorporates ACCU-ND technology for accurate color reproduction, easy maintenance and protection from infrared contamination that may affect the color balance of the image when shooting under the daylight. The just-fit frame with screw type mount secures the filter on the camera, and the allweather protective case will allow using these filters in different shooting conditions.

Why IRND filters are so important

SHUTTER SPEED

For natural and smooth looking motion In video shooting, it is fundamental to keep the shutter speed fitting the frame rate setting, that is, to keep it equal to double the frame rate for optimal results. This is because, unlike still photography, an excessively fast shutter speed may create a jarring effect and produce afterimages that will not look good at all in the final video.

As you can see from the image below, unlike still image, video clip is made of a sequence of still images. With low shutter speed, each still image will blur but will look smooth in the video sequence. On the contrary, a higher shutter speed will capture the object solid and sharp, but once in a video sequence all objects will appear separated, creating jarring and unnatural looking motion.

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

APERTURE

For optimal exposure

Drones are mostly used outdoors in day time, high-lit environments. Since DJI Mavic Air is equipped with a camera module that has a fixed aperture of f/2.8, and ISO setting should be set at the minimum level of ISO100 for image quality sake, IRND filters are strongly suggested as a necessary ad-on accessory 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 appropriate shutter speed setting during a sunny day in a snowy mountain area.

ACCURATE NEUTRALITY

High-quality IRND filters are required to be extremely and accurately neutral to prevent color shift or IR pollution from affecting the final image.

Accurate neutrality of Kenko IRND filters is achieved by adopting ACCU-ND Technology that is exclusively developed for DSLR camera filters. ACCU-ND Technology provides constant and fine-adjusted light density within a wide spectrum range, including the infrared area (400nm-1000nm).

4 in 1 kit in ALL-WEATHER PROTECTIVE CASE

Kenko Advanced Drone Filters IRND kit contains 4 filters of different density to choose from depending on the light conditions at the shooting location. Choosing the right density value will allow fine adjustments of the camera setting according to the different light conditions, thus avoiding diffraction and obtaining optimal exposure of the image.

Also, for better and convenient utilization in outdoor environments, Kenko Advanced Filters IRND kit comes within an all-weather case that will keep filters all together and protect them from moisture and dust, rain or snow.

EASY TO MAINTAIN

Anti-reflection multi-layer coating of Kenko IRND filters is blended with a water-repellent layer. This ensures protection from fingerprints, smudges, dust, thus making filters easy to clean and maintain in ready-to-use conditions.

How to choose the right IRND filter

The table below can serve as a basic guide to choose the right IRND filter.

Since DJI Mavic Air is equipped with a camera module that has a fixed aperture of f/2.8, in a very sunny day IRND16 or IRND32 filter is commonly suggested to be attached by default in order to lower the shutter speed up to 1/125s or 1/60s depending on what fps mode you shoot with.

table_1

In case of drones equipped with changeable aperture camera modules, when shooting video it is recommended to use aperture stepped 2-3 stops up from wide-open position. In high-lit environments above the ground and with related to fps mode shutter speed, you would need IRND filters to obtain the optimal aperture. For example, at a shutter speed set at 1/125s you will get f/11. You will then need to attach IRND4 to step down to f/5.6, or IRND8 to step down to f/4. Or, with the aperture set at f/5.6 and the frame rate at 60 fps, you will need IRND4 filter to slow shutter speed from 1/500 to 1/125.
