This is the Lee Neutral Density Soft Graduated Set (75x90mm Resin) [S5NDGSS]
The Lee Neutral Density Grad set is available for the Seven5, 100mm and SW150 filter systems and is available in either hard or soft edge. The set contains graduated resin filters that enable the photographer to adjust exposure over part of the photograph without affecting colour balance. Exposure can be controlled by 1, 2 or 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.
