How They Work?

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 façade of pastel colour 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.

The filter is available in these densities

  • Irix Edge Reverse Gradual Filter (0.9) 3EV nano IR 100x150mm

Functional Filter Case

Each and every Irix Edge 100mm Filter comes with a functional Filter Case made from rigid foam mounted on silicone frame, and fitted with a magnetic lock, so you can be sure that your filter is secure during transport or storage.

European Brand

The Irix Edge brand has its roots in Europe – this is where they are designed, tested and improved by our research team, using the latest measurement equipment and under rigorous quality control. All the effort put into the product development makes us sure that you can trust them in any, even the most demanding conditions.

Pure technology just for you

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 colours 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 colours in any weather conditions.
