ND16 Neutral density Filter

ND16 Neutral density Filter

The purpose of nd16 Neutral density filter is to weaken all the light, change only the exposure of the film, and will not have any impact on the relative light and dark value of the scene. We can use the medium gray density mirror to change the brightness of the light, so as to adjust the exposure of the film to varying degrees. The effect is equivalent to shrinking the first stop, second stop, third stop or even more stop apertures. Of course, this does not mean that adjusting the aperture of the camera can replace the Neutral density film. For example, in extreme environments, when the light is very strong, the Neutral density film has greater adjustment flexibility to the aperture and exposure time.
