The LEE Filters 100 x 150mm Medium-Edge Graduated Neutral Density Filter Set is a versatile kit containing 1-stop, 2-stop, and 3-stop graduated neutral density filters that are compatible with a LEE Filters 100mm System filter holder. Each filter within this kit helps 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. Each filter is densest at the edge and tapers to clear by the middle, with a medium-edged line of transition between the dense and clear areas. A neutral density filter with a medium-edged line of transition is able to filter the sky while minimizing its effect on the land, making it particularly useful for images that include elements like rooftops and mountains that protrude into the sky.

These filters are constructed from optical-quality resin for clarity and color fidelity. For storing, transporting, and cleaning each filter in the LEE Filters 100 x 150mm Medium-Edge Graduated Neutral Density Filter Set, a soft, three-pocket microfiber wrap is included.
