Studio : Formatt Hitech Limited Publisher : Formatt Hitech Limited Binding : Electronics Product Description The Grad Kit 7 contains a complete set of the Reverse Grad Neutral Density filter - 0.3 (1 Stop), 0.6 (2 Stops) and 0.9 (3 Stops) to maximize the effectiveness of your sunrise and sunset photography. Save over 23% 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. The reverse grad is a vital tool if you are looking to take sunrise or sunset shots. This is because the ND part of the grad is upside down, with the darker part at the middle of the filter and the lighter part at the top. This ensures the maximum light reduction when the sun is at or near the horizon. 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. 0
