Save over 22% compared with purchasing the filters separately. Neutral density (or ND) filters produce a grey neutral tone and are used in photography to reduce light, enabling more control over exposure and depth of field without affecting color contrast. NDs are also available in graduated filters, both in hard and soft edge. These filters are clear in the bottom half of the filter with a gradual transition to the ND effect in the top half. They are primarily used for light reduction in skylines of landscape shots. Graduated NDs are available in Soft Edge or Hard Edge varieties. Soft edge grads have a smooth transition from clear to ND. Hard edge grads have a more defined hard lined transition and are usually used for longer focal lengths. ND Grads are made in different densities according to the level of light reduction from 1/3 to as much as 4 Stops of light. This 100mm filter kit is usable with Hitech 100mm holder systems or any 100mm holder. The filters in this kit are 100mm Wide but 150mm long to enable easy movement up and down in the holder. The kit is also available in 85mm, 150mm and 165mm sizes. Hitech filters are made from the highest quality 1.5mm optical resin.
