The Cokin Round Nuances ND1024 filter in mineral glass is made with innovative filter manufacturing technology. A completely new coating process has been developed to ensure uniform colours. A nano-metallic alloy is applied to both sides of the filter which is made of high-strength tempered Schott glass. This type of glass is known for its high light transmission and low reflection. The result is a beautiful neutrality, completely free of infrared pollution.
This grey filter has a 3.0 density and blocks ten stops of light over the entire image. This makes it possible to work with a more open aperture or slower shutter speeds. This is ideal in a high light environment and when you want to use certain settings in a setting where this is not possible with the existing light. You also have more control over depth of field.
