GNDs come in three different types, which offer various different graduation patterns Рthere are: Soft edge graduated neutral density filter Hard edge graduated neutral density filter Reverse graduated neutral density filter The graduation patterns for these three types can be seen in the diagram below. GNDs are useful when one part of your scene is much brighter than another. Typically this is the sky! The dark part of the filter is placed over the sky to hold back the brightness, and even it out with the foreground in the image. Soft edge filters are used when there are objects in the frame that stick up into the sky, such as mountains. Hard edged GNDs are used when there is a clear horizontal definition between...
