The Nuances Extreme ND8 (solid neutral density) reduces light transmission by 3 stops allowing the use of slower shutter speeds and wider apertures. Nuances Extreme filters are made from a new type of tempered optical glass that is 4 times stronger than the previous series. This means your new filters can travel with you into extreme conditions and withstand those inevitable drops and scratches that can happen to any photographer.A new Nano-Metallic Alloy coating process ensures uniform density.
This process results in stunning neutrality and absolute colour consistency throughout all types and densities in the series. So switching from one density or style to another will still yield the exact same colour results with no adjustments necessary. These filters have an industry standard 2mm thick glass and rounded corners to make them easy to insert into a filter holder.
