Lee Filters Seven5 ND Grad Set Soft Edge

The Lee Filters 75x90mm Seven5 Soft-Edge Graduated Neutral Density Filter Set contains 0.3, 0.6 and 0.9 graduated neutral density filters. These filters help to darken specific areas of an image, such as bright skies, while allowing for a normal, unaffected exposure in the other regions of the image. They are densest at the edge and taper to clear by the middle, with a soft-edged line of transition between the density and clear areas.The 0.3 density provides a 1 stop exposure reduction; the 0.6 density provides a 2 stop exposure reduction; and the 0.9 provides a 3 stop exposure reduction. These filters are constructed from a high quality optical resin for both imaging performance and durability. They are compatible with the Seven5 Micro Filter System, which is specifically designed for use with smaller interchangeable lens cameras. These Neutral density filters measure 3x3.5" / 75x90mm.
