Hitech 4x4" Neutral Density Kit with 3 filters: 1, 2, 3-stop (0.3, 0.6, 0.9)
The Hitech 4 x 4 inch 0.3, 0.6, 0.9 Neutral Density Filters Kit are clear in the bottom half with a gradual transition to the ND effect in the top half of the filter. They produce a grey neutral tone and are used to reduce light, enabling more control over exposure and depth of field without affecting color or contrast. Neutral Density graduated filters are primarily used for light reduction in skylines or landscape shots.
