Product Description

ND, short for neutral density, refers to filters that reduce entry of light without color deviation. ND filters is are important tools to reduce light entry, with which photos can be taken with large aperture and shallow depth of field in the bright light. With higher coefficient, long time exposure can be realized.

Main functions:

In the bright light, we cannot adapt large aperture so shallow depth of field cannot be achieved, which is needed in shooting portraits in order to separate the main character from the background, when large aperture should be adapted. In this situation, ND filters are good choice to attain ideal aperture.

ND4 25%(1/4) of light is allowed in or 75% is blocked out

ND8 12.5%(1/8) of light is allowed in or 87.5% is blocked out
