Set of three neutral density graduated filters (0.3, 0.6 and 0.9 - 1, 2 and 3 stops). Available in Soft or Hard cuts. 'Cut' refers to the rate of transition of the filter from clear to ND. 'Soft' is a more gradual change; 'Hard' has a rapid transition - favoured by many landscape photographers. Lee recommend a hard cut for use with smaller digital camera sensors.
