What is ND filter?
The ND filter only reduces the intensity of the light, so it does
not affect the color of the final image, nor does it affect the
white balance and automatic exposure of the camera. The use of ND
mirrors will not have any effect on the color and contrast of the
subject. In addition, since SLR cameras are used to measure light
through the lens, the ND mirror does not have any effect on the
camera's automatic exposure system.
In short, the ND mirror is a very useful additional lens when it is
necessary to artificially use a slow shutter, or to reduce the
amount of external light. Of course, different lens aperture is
different, we need to choose different caliber according to lens
aperture when use.
Key function:
1. Reduce the amount of light. For example, if you want to use a
large aperture in a very strong light, you can add a medium gray
mirror.
2. Extend the shooting time. For example, in the very bright place,
we want to photograph the foggy water.
3. When shooting the street view in the daytime, add a certain
number of gray mirrors, greatly lengthening the exposure time can
play a virtual pedestrian or even completely remove the role of
pedestrians and vehicles.
