DJI Air 3 ND Filters Set (ND8/16/32/64)

These filters are particularly useful because they enable a technique called 'shutter angle control'. Simply put, a shutter angle refers to how long the camera's shutter stays open relative to the frame rate during filming. For example, if you are filming at 24 frames per second (fps) and a shutter angle of 180°, this means that your camera's shutter will be open for 1/48 seconds for each frame. This setting is ideal for capturing movement in a way that looks natural to the human eye, and using ND filters makes it easier to maintain this setting, even in bright light, without overexposing the images.

In short, ND filters are essential for filmmakers who want to maintain high-quality footage in different lighting conditions.
