Graduated Neutral Density Filters

NANO COATING IR GND FILTERS | IDEAL GRADUATION

Cameras cannot expose the detail of extremely low light and dark scenes at the same time.  Graduated Neutral Density Filters are typically distinguished by the type of transition that exists between the transparent and dark areas of the filter.  For this reason, we can identify four families of GNDs.

Medium GND
Medium GND

MEDIUM GND FILTER

Medium GND Filter is a rectangular filter that helps to darken specific areas of an image, such as bright skies while allowing for a normal, unaffected exposure in the other regions of the image. It is particularly useful for images that feature buildings, mountains and other small elements that protrude into the skyline.

    SOFT GND FILTER

    Soft GND Filter is characterized by a soft transition (they change from light to dark more gradually) and is therefore used when the transition between light and dark areas is not so clear. A classic example is a shot in a mountainous area.

    HARD GND FILTER

    Hard GND Filter, which is characterized by a clear boundary (it’s obvious where one begins and the other ends) between the transparent and dark areas. They are therefore used when the separation between the bright and dark areas of your scene is very defined, such as the horizon at sea.

    REVERSE GND FILTER

    Reverse GND Filter, which is nothing more than hard-edge GNDs with the dark area that fades away the more you move from the line of separation to the upper border of the filter. Basically, they were invented to better manage sunrises and sunsets, where the light is more intense on the horizon line (middle).
