The Graduated Neutral Density Filter is used for Cinematography. 50% of the filter is clear and 50% has a Neutral Density of 0.6 (2 stops). The transition from clear to ND is done with a Soft Edge (SE) transition line. Soft Edge grads lines are used with wide angle and normal focal length lenses. Graduated Neutral Density filters are used to balance exposure within a scene. One very common use is to balance the exposure of sky and earth in a landscape, avoiding overexposed blank white skies.
