An alternative to buying several ND filters of different strengths is to buy a single variable ND filter. This consists of two polarising filters that can be rotated with respect to each other. When they are both aligned in the same direction, light passes through with between one to two stops of reduction in strength. Rotating the ring on the filter will cause the transmitted light level to drop until it’s almost totally blocked.

When to use anND filterfor video

A neutral density (ND) filter is an accessory which fits on the front of your camera lens and is used to reduce the amount of light passing through the lens, without affecting the colour balance.

Cutting down the light using a neutral density filter does not affect the depth-of-field, but will allow you to use longer shutter speeds for creative effects.

Ein Makro-Objektiv hat meist eine Festbrennweite zwischen 30 – 200mm und einen Abbildungsmaßstab von 1:2 oder 1:1. Das wird von Fotografen als Makro bezeichnet.

Nd filter what isphotography

Another reason to use an ND filter is when conditions are too bright for a given aperture. For example, if you want to use f2.8 for shallow depth-of-field on a bright sunny day, the camera’s maximum shutter speed might not be fast enough, even at a low ISO setting. An ND filter will allow you to use a slower shutter speed.

Solid and variable ND filters darken the entire image which allows the photographer to blur anything that is moving. I highly recommend purchasing solid ND ...

While a variable ND filter is a useful device for achieving several stops of adjustment, it is inadvisable to use it when fully cross-polarised as the resulting image can show uneven light reduction and a distinct colour shift.

At first sight, this might appear to be the function of the lens aperture, but changing the aperture affects more than just the transmitted light level.

There are two ways to designate ND filter strengths. It can be based on the fraction of light transmitted (first column), or on the optical density (second column). The third column shows the percentage of light transmitted by the filter, while the fourth column converts this to the equivalent number of stops. The final column shows the exposure time needed if 1/60 second is required without an ND filter.
