Kase Revolution R-GND 0.9 77mm
The Kase Revolution R-GND 0.9 77mm is a magnetic soft reverse grey gradient filter, including Adapter ring 77mm, recognisable by 3 orange reverse bars on the edge.
Thanks to the magnetic ring, this Revolution R-GND0.9 soft reverse grey gradient filter 77mm is easy to mount and remove on the Lens. The filter is made of high-quality Wolverine glass, this ensures that the filter is almost indestructible and colour-neutral. The magnetic filter can be mounted on a lens with the included magnetic adapter ring, but can also be used with the optional Revolution inlaid ring of 77mm. The edge of the filter has 3 orange reverse bars, which provide recognition, the bars also represent the number of stops of light, which the filter blocks.
R-GND (Reverse Graduated Neutral Density) Reverse gradient filter
R-GND gradient filters have a gradient, which varies in strength and density across the surface of the filter. Half the filters are clear and the other half is a GND grey gradient filter, which becomes lighter again at the top. When shooting with long Shutter speeds, it is important to be able to control the light, depending on where you want to block light, you can place the grey gradient filter in the right position.
In a landscape scène, the sky is normally brighter than the foreground and at sunrise/sunset, a fairly narrow beam of light around the sun is much brighter, so an R-GND filter is placed in front of the lens and moved to a position where the brighter part of the scène is covered by the R-GND Filter and the margin between sky and sun, along with the margin between the sun and the foreground blurred using the R-GND Filter's transition zones. The scène is normally measured for the highlight area and shadow area and the difference in stops dictates the strength of the filter used. Using an R-GND filter avoids the heavy darkening, normally associated with the use of stronger GND filters in sunrise/sunset cènes, the transition zones are normally soft.
