What is the function of the Royal 3ND Mirror?

The main function of the Royal 3ND mirror is to filter light and reduce the amount of light entering the camera lens, thus prolonging the exposure time. This kind of filter is widely used in photography creation, which can give photographers more freedom to control the aperture and shutter, bring more exposure means and creative space for photography creation, and effectively prevent overexposure.

In addition, the ND filter can also be used to capture the gesture of running water and show the passage of time in the picture more accurately. For example, when shooting time-lapse photography during the day, sufficient light often limits the adjustment of shutter speed. At this time, using ND subtractor can completely freeze the picture into frames, making the dynamic effect more natural.
