Graduated Filter Kit, made up of
graduated neutral density filters in densities: ND 0.3, ND 0.6, ND 0.9
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 also available as standard in 0.1, 0.2, 0.3, 0.6, 0.9 and 1.2 with heavier densities available to order (this is a set of 0.3, 0.6, 0.9).
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 should be used for longer lenses. For extremely long focal lengths a razor edge grad providing a very highly defined transition, may be ordered.
