The NiSi 150x150mm Square HD Polariser Filter reduces reflections so you are able to capture the true colour of scenes and improve the hue of the sky, which can be particularly useful when taking landscape shots.

Reduces Reflections

Polarising filters work by cutting out reflected light off things like water, leaves, tiles, and basically any surface that isn’t metallic. It is perfect when photographing anything that is underwater or for when you are shooting from behind glass to eliminate reflections.

Increase Colour Saturation

When using the polariser filter, you are able to improve the hue and saturation of colours. As the reflections are reduced, the natural colours of your scene become more vibrant and saturated. This is especially useful for example if you are photographing landscapes and want to darken the blues of the sky to capture a more interesting shot.

Variable Polarisation

The square HD polariser filter features the same design as a circular polariser meaning you can adjust the intensity of the polarisation by rotating the filter. This ability to change the intensity means you can brighten the shot to autofocus and then simply rotate to darken the frame to achieve the desired effect.

Ultra-Thin Design

The Polariser Filter has an ultra thin design and is 2mm thick, which helps to reduces the chance of vignetting especially when it is used with the wide angle lenses popular with most landscape photographers.

Low Colour Shift

One of the important considerations when using filters in your photography is that the colours do not get effected by sticking a filter in front of the lens. The Nisi filter features a low colour shift to ensure that optical precision is maintained this reduces any pronounced colour cast which would have to be removed in post processing.

High Quality Build

The Ni Si 150x150mm Square HD Polariser Filter has a sturdy build consisting of polarised optical glass created with precision grinding and polishing. Along the edge of the filter there is blackened glass to stop any reflected light entering from the edge. This build quality ensures that you can always enjoy a high optical performance when using the filter.
