100mm System | LEE Filters B&W - Technical

These filters each have a different effect on the tones in a black and white image by absorbing different quantities of colour in the blue and blue-green parts of the spectrum. The black and white filters can also be used for special effects.

The Colour Correction filters in this range can be used either in front or behind the lens to reduce the transmission of light at specific wavelengths. Their primary use is to colour balance films, however the effect of each filter must be determined by tests or specified by the film manufacturer. These filters are also useful for correcting light source for which no standard conversion filter exists, or introducing a deliberate colour bias.

Lee Filters Low Contrast filters work by spreading light from the highlights to the shadowed and darker areas, leaving the bright areas of the image bright. The dark areas become lighter, enabling you to see more detail in the shadow areas. As there is no F-stop compensation, you will not overexpose any portion of the image. This filter also creates a very slight flare or halation around hot spots and individual light sources. This feature is a useful effect. The more light there is for the filter to work with, the greater the effect. This filter is very popular with people who shoot video but who want to achieve more of a film look to their images.
