Vivitar VFK43C Video Filer Kit 43mm UV CPL ND This 43mm Digital Filter Kit includes an ND4 filter a circular polarizer filter and a UV filter. ND4 Filter This neutral density 0.6 filter enables a two stop increase in exposure. It darkens the entire image allowing you to photograph with a wider aperture or slower shutter speed than normally required. By slowing your exposure time or increasing your aperture you are able to control depth of field and convey movement more easily. Neutral density filters do not affect the overall coloration of the image. UV Filter The UV filter is a general use clear filter that helps to absorb ultraviolet light and reduce the bluish cast of daylight. No additional coloration or contrast is provided allowing you to pair this filter with others. The UV filter is also useful as a general protective filter to leave on lenses at all times. Filters help to reduce dust and moisture from reaching your lens element and provide additional protection in case of drops or situations where scratching could occur. Circular Polarizing Filter The circular polarizing filter helps to reduce reflections and glare by filtering out light that has become polarized due to reflection from a non-metallic surface. This results in a noticeable increase in the saturation of skies and foliage as well as clearer imagery when photographing in hazy conditions. A circular polarizer differs from a linear polarizer in that it supports full use of a camera s autofocus and auto exposure functions.
