Irix Edge 100mm Soft Gradual Filter

The Irix Edge Soft Gradual Filter allows obtaining a natural tonality of the image when shooting scenes with irregular horizons such as forests and mountainous areas, as well as urban scenes.

Highest quality optical glass which guarantees high light transmission.

Light from behind an irregular horizon

The Irix Edge 100mm Gradual Filter reduces the amount of light in a specific area of the picture, thus allowing us to achieve proper exposure within the entire frame of the picture.

Why to use the filter?

When we want to get that fantastic shot of another stunning landscape and we find out that our camera can’t register the whole range of photographed scene – there are blown out highlights or underexposed shadows.

This type of filter is especially useful when we want to photograph a scene with an irregular horizon line, such as in the mountains, the city, the forest.

The Irix Edge 100mm Soft Gradual Filter is a type of tinted filter which has a long transition between full transparency and maximum density (about one third of the filter’s height), so it’s especially useful in an area with an irregular horizon line – that is, when the sky (naturally the brightest part of the image) should be covered by the more tinted part of the filter, the irregular horizon line by the gradual, and the dark part of the image with the transparent part of the filter.

The filter is available in these densities

  • Irix Edge 100 Soft nano GND4 0.6
  • Irix Edge 100 Soft nano GND8 0.9
  • Irix Edge 100 Soft nano GND16 1.2
  • Irix Edge 100 Soft nano GND32 1.5

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

Irix Edge Soft Graduated is a type of filter which reduces an amount of light reaches the camera sensor in a specific area. This kind of filter is irreplaceable every time when photographing the urban or mountain landscape with an invisible horizon line, allowing spectacular effects without using the HDR effect.

Irix Edge filters are characterised by the highest precision and optical quality to be able to meet the image quality generated by high resolution camera sensors. Both surfaces of the glass filter are covered by the multilayer antireflex and water/oil-proof coating providing high light transmission and natural colours in any weather conditions.
