The Formatt-Hitech 100 x 100mm and 100 x 125mm Neutral Density Filter Master Kit contains six different neutral density filters; both 100 x 125mm hard-edged graduated and 100 x 100mm solid filters.
The solid ND filters included are 0.3, 0.6, and 0.9 densities, offering exposure reduction of 1, 2, and 3 stops respectively. An ND filter creates a darkening of 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. These filters measure 3.9 x 3.9" / 100 x 100mm and are constructed from specially dyed CR-39 resin.
The ND Grad filters included are 0.3, 0.6, and 0.9 densities, offering exposure reduction of 1, 2, and 3 stops respectively. A graduated ND filter has density on half of the filter surface, helping to darken skies and other bright areas of the image. The filter is most dense at the edge and abruptly tapers to clear by the middle of the filter. The filters measure 3.9 x 4.9" / 100 x 125mm and are constructed from specially dyed CR-39 resin.
Kit includes 0.3, 0.6, 0.9 solid ND 100 x 100mm filters and 0.3, 0.6, 0.9 hard-edged graduated ND 100 x 125mm filters.
Solid ND filters darken the image, allowing you to photograph with a longer shutter speed or wider aperture than normally required. These filters allow you to control depth of field and convey movement more easily.
Graduated ND filters provide selective darkening for controlling the exposure of the sky or other bright areas of the image.
Neutral density filters do not affect the overall coloration of the image.
