Soft Gradual Gray 0.9

Graduated Neutral Density Filters – GND

Graduated ND filters are used to control the dynamic range within a scene at the time of capture. In a landscape scene the sky is normally brighter than the foreground so a GND filter is inserted in front of the lens and moved to a position where the brighter part of the scene is covered by the GND filter and the margin between sky and foreground is faded using the transition area of the GND filter.  The scene is normally metered for highlight area and shadow area and the difference in stops dictate the strength of filter used. With modern digital sensors a S-GND (soft) filter offers the most versatile solution for landscape photographers.
