The Irix Edge Reverse Gradual Filter is a relatively new type of filter that combines the features of a hard and soft filter, particularly finding its application when it comes to sunset and sunrise photography. Probably every one of us has tried at least once to capture that beautiful view of the sun emerging from the horizon, after which we end up encountering a problem; either the frame was visible, the sun and the horizon has turned into a white spot, or we've managed to somehow capture the sun complete with a beautiful facade of pastel color background of black emptiness.
However, the design of this filter allows us to eliminate such problems, being a filter that is half transparent with hard edge (Hard Gradual), and then gradually reducing the density (Soft Gradual). Such a construction ensures that it covers the narrow spectrum of the frame within the horizon line, and so allowing us the possibility to ensure the correct exposure of the photograph.
High contrast scene when the sun is right above of the horizon needs to reduce the amount of light reaches the sensor of the camera to counteract overexposed part of a scene. The effect of using the filter gives you the properly exposed picture with natural and clean colors without using of HDR effect.
Irix Edge Reverse Neutral Density filter does not affect the coloration of the image and reduces the amount of light entering the lens in the central part of an image. All of the Irix Edge filters are characterised by the highest precision and optical quality to be able to meet the image quality generated by Irix lenses. Both surfaces of the glass filter are covered by the multilayer anti-reflex and water/oil-proof coating providing high light transmission and natural colors in any weather conditions.
