Why Reverse GND Filter?
Nisi reverse ND filter is designed with dark area on the center of the filter and gradually clearer to the top while the bottom part is clear preventing over exposure of skyline. This allows scenes with bright horizons such as sunsets to be brought back to within correct exposure levels, and improves the contrast of the ground area that would otherwise be over or under exposed. The graduation is slightly feathered to avoid a hard line.
Soft vs Hard vs Reverse GND Filter
Cameras cannot expose the details of extremely low light and dark scenes at the same time. In order to avoid the loss of any detail (in the lights or the darks), photographers use GND Filters to reduce the exposure of the bright parts, which can balance the bright and dark parts of a scene.
Soft GND 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.
Reverse GND Filter
Reverse GNDs are basically Hard GND filters with the darkest fading away 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.
Hard GND Filter
Usually defined by a 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.
Why Choose NiSi GND Filters?
i) High Definition
NiSi filters are made from fine annealed optical glass H-K9L. Optical grinding and polishing on both sides ensure the high definition of the glass. Other filter brands use resin which can deform in high and low temperatures which will effect the clarity.
ii) Ultra low colour cast
NiSi has developed a gradual nano coating which allows ultra violet to near inferred light to pass through the glass evenly. When this type of light passes through the glass evenly it has no colour cast.
NiSi filters have a double sided anti-reflective coating reducing any reflection that may appear when using the filters. NiSi filters also have a waterproof, oil repellant and hardened coating making the filters easier to clean.
