ND Gradient
Description
ND (Neutral Density) Gradient darkens only a portion of the image using a graduated transition between the darkened portion and the original image. It selectively adjusts brightness without affecting color balance. The most likely use for ND Gradient would be to balance the difference between the sky and ground in a landscape.
