The Purpose of Neutral Density Filters

Neutral density (ND) filters can turn an ordinary landscape photo into a dramatic event by filtering light for artistic effect.

Cambridgeincolour.com describes an ND filter as a device that blocks a certain amount of light from the camera sensor in a uniform grade or density.

ND filters can smooth motion from images such as waterfalls or oceans, reduce the visual impact of moving objects in the image or add a blur to rapid motion for dramatic effect.

Manufacturers rate their ND filters by what fraction of light they block. "Do you want to learn digital photography techniques that carry professional photographers to where they are today? Well, The Top Secret Photography Techniques might support you out in doing so. To find spectacular photos we first want to look at some essential photography strategies. The most important one I am able to share with you is uncover about light. You can discover everything concerning photography techniques on , The Top Secret Photography Techniques. Whenever you discover about light and in what technique it interacts with the direct environment then your photographs will get improved..". The lightest filter, which blocks only half the available light, receives a rating of ND2, while an ND64 filter blocks all but 1/64th of the light.

A graduated neutral density (GND) filter blocks light in a gradual darker-to-lighter pattern instead of uniformly across the entire frame.

Cambridge Colour notes that while neutral density filters produce dramatic lighting effects, any filter can introduce unwanted visual artifacts into the image, such as lens flare, reduced contrast, or even blackening at the edges of the image.
