High definition Multi-layer coating Hard Graduated ND filter

What is a Graduated ND filter?

Graduated ND filter is one of the most important filters for photographic art creation.

Like ND Filter, the GND filter( Graduated Neutral Density)can allow less light to enter the camera. As a graduated ND filter with half part transparent and half part dark, this enables you to reduce the part of the light.  The difference between these 2 filters is that the GND filters only darken part of the image while the ND filter darkens the whole image.

-BEFORE & AFTER GND EFFECTS-

GND filter--Soft GND vs Hard GND vs Reverse GND vs Center GND

• Soft Graduated ND Filter

Usually defined by no obvious transition between the bright and dark area of the scene.  Soft GNDs are therefore used where the transition between light and dark areas is not so clear. An example is a shot in a mountainous area, or trees etc.

• Hard Graduated ND Filter

Usually defined by an obvious boundary between the bright and dark area of the scene. They are therefore used when the separation between the bright and the dark areas of the scene is very defined, such as the horizon line or the boundary between sea level and the sky.

• Reverse Graduated ND filter

Reverse GNDs are basically Hard GND filters with the darkest fading away from the further you move from the line of separation to the upper border of the filter.  They are perfect for managing sunrises and sunsets, where the light is more intense on the horizon line.  If you love shooting sunrise and sunset this filter is a must-have.

• Center Graduated ND filter

It is mainly used for sunrise and sunset photography. When the sun is going to set, the center is too bright and cause overexposure, while the top and bottom are dark. With the center graduated ND filter, you will get transition effect and even light, and detail of center area. Center graduated ND filter fills the gaps of soft graduated ND filter, hard graduated ND filter, and reverse graduated ND filter.
