HD Square Polariser
The NiSi 150x150mm Square HD Polariser filter helps to reduce reflections and glare by filtering out light that has become polarised. The light from the sun naturally becomes partially polarised due to reflecting off electrons in air molecules, causing the light to scatter into what appears as haze. A polarizing filter arranges, and filters, this directionally polarized light, the result is a noticeable reduction of glare and reflections and an increase in the saturation of skies and foliage.
Manufactured using the highest quality Nito polarisation film, the edges are blackened to prevent light reflecting through the edge.
Although a square CPL will not allow circular rotation when also using a Graduated ND Filter, the effect can be altered as show about. It can be useful in some instances where a lens does have a filter thread but vignettes using a circular polariser
