Lee Filters 150x170mm Neutral Density Very Hard-Edge Graduated Resin Filter Set for SW150 System Filter Holder

Available in optically correct resin. Due to the size of the front element of ultra-wide angle lenses, the filters for the SW150 system are larger than those in the standard 100mm range: these graduated filters are 150 x 170mm. The Neutral Density Set contains graduated resin filters that enable the photographer to adjust exposure over part of the photograph without effecting color balance. Exposure can be controlled by 1, 2 and 3 stops.

For example, when photographing a landscape in which the sky is much brighter than the foreground, placing the Neutral Density part of the filter onto the sky in the frame will reduce the sky exposure without effecting the foreground. This enables cloud detail to be kept correctly exposed and avoids the "white out" effect caused by exposing for the foreground. Available in a range of gradations between the coated and clear areas of the filter giving precise exposure control in a range of situations.
