The Irix Edge Soft Graduated ND4 filter with optical density of 0.6 provides a 2 stop reduction of light hitting the sensor of the camera. It is irreplaceable every time when photographing at a scenary with an invisible line of the horizon such as the forest, urban or mountain landscapes allowing spectacular effects without using the HDR effect.
Irix Edge filters are characterized 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 antireflex and water/oil-proof coating providing high light transmission and natural colours in any weather conditions.
