A soft edge grad filter is recommended when the variation in light readings within a scene is less pronounced or the horizon line has any deviation, such as mountains, trees or rock formations. The soft edge grad filter is also used on occasions when the effect of a hard edge grad would be apparent in the resulting image, showing as a ‘line’ across the composition. The transition in tones, from bright to dark, should appear very natural when using a soft grad.
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.
