1. ND filter reduces the amount of light coming into the sensor, giving you the freedom to create your own work by allowing more conTBol of the cameras aperture, exposure time and sensor sensitivity settings.The numbers in the back represent the dimming lev.
2. The main purpose of using the ND lens is to prevent overexposure during shooting. Suitable for daylight or when the light is too bright, use large apertures and slow shutter speeds to create special effects.
3. Record the movement of the subject with a slower shutter speed when shooting;
4. When shooting with a large aperture, the depth of field range will be reduced to separate the subject from the background. For example, if you need to shoot the water at a slow shutter speed to make it look like a special effect, then you need to use an ND dimming mirror.
